Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?
Rationale:
Providing meals at the same time insulin lispro is given ensures optimal blood glucose control and prevents hypoglycemia. Insulin lispro is a rapid-acting insulin that works quickly to lower blood sugar after eating, so coordinating meal timing with its administration is crucial to match insulin action and glucose availability.
A: Checking blood glucose every six hours lacks the immediacy required for rapid-acting insulin management, potentially missing critical fluctuations and delaying necessary interventions for hypoglycemia or hyperglycemia.
B: Assessing for hypoglycemia between meals is important but insufficient alone; the timing of meals relative to insulin lispro administration is more critical to prevent hypoglycemic episodes from occurring.
D: Keeping an oral glucose source available is a safety measure but does not actively prevent hypoglycemia; coordinating meal timing with insulin administration directly addresses glucose-insulin balance.
The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately? Reference Range: Sodium [Adult 136 to 145 mEq/L (136 to 145 mmol/L)] Digoxin level [0.8 to 2.0 ng/mL (0.6 to 13 nmol/L)] Potassium (K+) [Adult: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)]
Rationale:
A potassium level of 3.2 mEq/L (3.2 mmol/L) should be reported to the healthcare provider immediately.
Hypokalemia increases the risk of digoxin toxicity by enhancing digoxin’s effects on cardiac cells. This low potassium level falls below the normal range (3.5 to 5.0 mEq/L) and requires prompt intervention to prevent serious cardiac complications in a patient taking digoxin.
A: Sodium level of 135 mEq/L (135 mmol/L) is just below normal but does not directly influence digoxin toxicity or urgent clinical decisions.
B: Creatinine level of 0.8 mg/dL (70.77 µmol/L) is within normal limits and does not indicate impaired renal function affecting digoxin clearance.
D: Digoxin level of 1.1 ng/mL (1.4 nmol/L) is within the therapeutic range and does not necessitate immediate reporting or intervention.
A patient with open-angle glaucoma asks the nurse about the duration of use for the prescribed eye drops. What is the nurse’s accurate response?
Rationale:
Eye drops for open-angle glaucoma are used for long-term control of normal eye pressure.
This answer is accurate because open-angle glaucoma involves chronically elevated intraocular pressure that requires continuous management. Eye drops help maintain eye pressure within a safe range to prevent optic nerve damage. Treatment is lifelong, as glaucoma cannot be cured, only controlled by consistently lowering and stabilizing intraocular pressure.
A: For long-term control of pain and swelling. This option misrepresents glaucoma treatment, which targets pressure reduction, not pain or inflammation control.
B: Until a smaller angle can be restored. Open-angle glaucoma involves a normal angle; the angle itself is not altered or restored by drops.
C: Until the excess pressure is reduced. Pressure management is ongoing; drops do not stop once pressure is initially lowered but continue indefinitely for control.
A client with end stage emphysema is experiencing poor gas exchange. Which respiratory structure is associated with the pathophysiological processes in emphysema?
Rationale:
Emphysema primarily affects the alveoli.
The alveoli are tiny air sacs where gas exchange occurs; in emphysema, their walls are damaged and destroyed, reducing surface area and impairing oxygen and carbon dioxide diffusion. This deterioration leads to poor gas exchange, hallmark symptoms of end-stage emphysema, directly linking alveolar damage to the disease’s respiratory complications.
A: Bronchioles regulate airflow but are not the primary site of gas exchange impairment in emphysema, which mainly involves alveolar destruction.
B: Trachea serves as the main airway conduit and does not participate directly in gas exchange or the alveolar damage characteristic of emphysema.
C: Bronchi conduct air into the lungs but lack the delicate structures where gas exchange and emphysema-related damage occur, making them less relevant here.
A client who received a renal transplant three months ago is readmitted to the acute care unit with signs of graft rejection. While taking the client’s history, the nurse determines that the client has been self-administering St. John’s Wort, an herbal preparation, on the advice of a friend. Which information is most significant about this finding?
Rationale:
St. John’s Wort can decrease plasma concentrations of cyclosporine.
This is significant because cyclosporine is critical for preventing graft rejection by suppressing the immune response. St. John’s Wort induces liver enzymes that metabolize cyclosporine faster, lowering its blood levels and reducing its effectiveness, which increases the risk of transplant rejection and explains the client’s current symptoms.
A: Ingestion of St. John’s Wort can reduce the client’s intake of sodium. This statement is unrelated to the herb’s pharmacological impact on immunosuppressant drug levels or transplant outcomes.
B: Adding the herb can decrease the need for corticosteroids. The herb does not reduce corticosteroid requirements or alter their immunosuppressive effects in transplant patients.
C: The client probably used this herb to treat depression. While true, this does not address the critical interaction causing graft rejection in this context.
A client with nasal congestion receives a prescription for phenylephrine 10 mg by mouth every 4 hours. Which client condition should the nurse report to the healthcare provider before administering the medication? Which condition should the nurse report to the healthcare provider before administering the medication?
Rationale:
Phenylephrine should not be administered without consultation if the client has hypertension. Phenylephrine is a vasoconstrictor that can elevate blood pressure, posing significant risks for clients with hypertension. Reporting this condition allows the healthcare provider to evaluate potential adverse cardiovascular effects and adjust treatment to ensure client safety and prevent exacerbation of hypertensive complications.
A: Diarrhea does not directly interact with phenylephrine’s vasoconstrictive effects and generally does not require withholding the medication or reporting before administration.
B: Bronchitis involves respiratory inflammation but does not contraindicate phenylephrine use or necessitate prior reporting to the healthcare provider.
D: Edema may be a symptom of underlying issues but is not a direct contraindication for phenylephrine and does not mandate reporting before drug administration.
The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client? Which instructions should the nurse provide the client?
Rationale:
Avoid crowds and people who are sick.
Adalimumab is a TNF inhibitor that suppresses the immune system, increasing infection risk, especially when combined with methotrexate. Clients should avoid exposure to contagious illnesses and crowded places to minimize infection chances. This precaution helps protect immunocompromised individuals from potentially severe infections, ensuring safer management of rheumatoid arthritis treatment with these immunosuppressive agents.
B: Undergo annual eye examinations. Annual eye exams are not specifically necessary due to adalimumab or methotrexate use, as these drugs do not commonly cause ocular side effects requiring routine screening.
C: Obtain routine vaccinations as scheduled. Live vaccines are contraindicated with immunosuppressants like adalimumab, so routine vaccinations must be carefully timed or avoided, not simply followed as usual.
D: Have a chest x-ray prior to your first dose. Chest x-rays are recommended primarily to screen for latent tuberculosis before starting TNF inhibitors, but the priority instruction focuses on infection avoidance after treatment begins.
A male client is admitted for observation because he is reporting progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. He has a history of heartburn and indigestion that he self-treats with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider? Reference Ranges: Hemoglobin [14 to 18 g/dL (8.7 to 11.2 mmol/L)] Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Gastric pH [1.5 to 3.5]
Rationale:
Positive guaiac of stool should be reported immediately to the healthcare provider. This finding indicates the presence of occult blood in the stool, suggesting gastrointestinal bleeding, which aligns with the client’s history of ibuprofen use and heartburn, and explains his progressive fatigue and dizziness due to potential anemia from chronic blood loss requiring urgent evaluation and intervention.
A: Hematocrit 42% (0.42 volume fraction) falls within normal limits, showing no immediate concern for blood volume or red cell concentration abnormalities needing urgent reporting.
B: Hemoglobin 13 g/dL (8.07 mmol/L) is slightly below normal but not critically low to explain acute symptoms or demand immediate attention in this clinical context.
D: Gastric pH 2.0 is within the normal acidic range, indicating normal stomach acidity and unrelated to the urgent symptoms or signs of bleeding requiring prompt action.
The nurse is teaching a client who has been diagnosed with human immunodeficiency virus (HIV) about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Rationale:
Antiretroviral medication prevents the transmission of the virus.
This statement requires additional instruction because antiretroviral therapy (ART) reduces viral load, lowering transmission risk but does not completely prevent transmission. Clients must understand ART is part of a comprehensive prevention strategy including safe practices. Misunderstanding this can lead to risky behaviors, so reinforcing correct knowledge about transmission prevention is essential for effective HIV management.
A: HIV infection is not cured by the antiretroviral regimen. This acknowledges ART’s role in control without eradication, reflecting accurate understanding of HIV treatment limitations.
B: The viral load can be decreased to an undetectable level. This correctly describes ART’s goal to suppress viral replication, improving health and reducing transmission risk.
D: The medications can decrease acquired immunodeficiency syndrome (AIDS) related complications. This highlights ART’s effectiveness in preventing disease progression and associated health problems, supporting long-term client wellbeing.
A client taking atorvastatin develops an increased serum creatine phosphokinase (CK) level. The nurse should assess the client for the onset of which problem?
Rationale:
Muscle tenderness is the problem the nurse should assess for when a client taking atorvastatin develops an increased serum creatine phosphokinase (CK) level. Elevated CK indicates muscle damage or inflammation, commonly linked to statin-induced myopathy, which manifests as muscle pain, weakness, or tenderness. Early detection prevents severe complications like rhabdomyolysis, ensuring timely intervention and client safety.
A: Peripheral edema Peripheral edema involves fluid accumulation in tissues, unrelated to elevated CK or muscle injury caused by atorvastatin. It typically results from cardiac, renal, or hepatic issues, not statin-induced muscular damage.
C: Nausea and vomiting These gastrointestinal symptoms do not correlate directly with increased CK levels or muscle injury from atorvastatin. They usually arise from other causes like medication side effects unrelated to muscle breakdown.
D: Excessive bruising Excessive bruising reflects coagulation or platelet problems, not muscle damage indicated by high CK. Atorvastatin primarily affects muscle tissue, so bruising is not a typical manifestation in this context.
A female client with osteoporosis has been taking a weekly dose of oral risedronate for several weeks. The client calls the clinic nurse to report increasing 'heartburn.' How should the nurse respond? How should the nurse respond?
Rationale:
Ask the client to describe how she takes the medication.
This response is appropriate because improper administration of oral risedronate commonly causes esophageal irritation and heartburn. Understanding the client’s method helps identify if she is taking it correctly—such as with a full glass of water, remaining upright, and not lying down immediately—which are crucial factors to prevent adverse gastrointestinal effects.
B: Suggest use of an antacid two hours after the medication. Antacids may interfere with risedronate absorption, reducing its effectiveness. Advising antacid use without assessing administration technique overlooks the primary cause of heartburn related to improper intake.
C: Remind the client to take the medication with plenty of water. While important, this advice alone doesn’t address whether the client remains upright or avoids lying down, both critical to preventing esophageal irritation and heartburn associated with risedronate.
D: Advise the client to go to the nearest emergency department. Immediate emergency care is unnecessary unless severe symptoms or complications are present. Initial assessment of medication administration is more appropriate to determine the cause of heartburn.
To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?
Rationale:
Clients using the discus should not use it more than twice daily. This combination inhaler contains a long-acting beta2-agonist and corticosteroid, designed for maintenance, not rescue, with dosing limited to twice daily to prevent side effects and ensure optimal control of asthma symptoms over time.
A: Clients using the discus may experience decreased blood pressure. This medication primarily affects airway muscles and inflammation, not systemic blood pressure, so decreased blood pressure is not a typical side effect.
C: When using the discus, have the client breathe out rapidly into the mouthpiece. Proper use requires a slow, deep inhalation after exhaling fully, not rapid exhalation into the device, to ensure medication reaches the lungs effectively.
D: Offer the discus to the client for use during an acute asthma attack. This inhaler is for long-term control, not immediate relief; short-acting bronchodilators are appropriate for acute asthma exacerbations, not combination maintenance inhalers.
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective? Which finding best indicates that the medication is effective?
Rationale:
Hemoglobin level increased to 12 g/dL (7.45 mmol/L).
An elevated hemoglobin level directly reflects the effectiveness of epoetin alfa, as this medication stimulates red blood cell production, improving oxygen-carrying capacity. Monitoring hemoglobin quantitatively confirms therapeutic success, especially in anemia related to CKD, where erythropoiesis is impaired. Clinical improvement correlates with laboratory values, making hemoglobin a crucial objective indicator of response to treatment.
A: Reports of increased energy levels and decreased fatigue. Subjective improvements may occur, but they do not objectively confirm epoetin alfa’s effectiveness without laboratory verification of hemoglobin levels.
B: Food diary shows increased consumption of iron-rich foods. Dietary changes alone do not demonstrate epoetin alfa’s direct impact on red blood cell production or anemia resolution.
C: Takes concurrent iron therapy without adverse effects. Tolerating iron therapy is important but does not measure epoetin alfa’s efficacy in increasing hemoglobin concentration.
A client receives a prescription for allopurinol. Which information provided by the client requires additional instruction by the nurse?
Rationale:
A: Avoid taking on an empty stomach. This advice helps prevent gastrointestinal discomfort, a common side effect when taking allopurinol. Taking it with food minimizes stomach irritation and enhances tolerance, promoting adherence to the medication regimen and ensuring effective management of uric acid levels in clients with gout or hyperuricemia conditions.
B: Reduce caffeine and acidic intake. While caffeine and acidic foods may influence uric acid levels, this instruction is not as critical as hydration and dosing guidelines for allopurinol efficacy and safety. The primary focus is on medication adherence and side effect management rather than dietary restrictions alone.
C: Consume 2 liters of water daily. Adequate hydration facilitates renal excretion of uric acid and reduces the risk of kidney stone formation during allopurinol therapy. This instruction supports drug effectiveness and prevents complications, making it an essential part of patient education.
D: Double the dose if a dose is missed. Doubling the dose after a missed one can lead to toxicity and adverse reactions. Allopurinol requires consistent dosing without abrupt increases, so this action necessitates immediate correction and additional nursing instruction.
The nurse is reviewing the client’s laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease? Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect?
Rationale:
Atorvastatin effectively lowers low-density lipoprotein (LDL) cholesterol levels in the blood.
LDL cholesterol is often referred to as "bad cholesterol" because high levels contribute to plaque buildup in arteries, increasing coronary artery disease risk. Atorvastatin works by inhibiting HMG-CoA reductase, reducing LDL production and promoting its clearance, thereby demonstrating its therapeutic effect through decreased LDL serum values in clients.
B: High-density lipoprotein (HDL) represents "good cholesterol," which atorvastatin may modestly affect, but HDL levels are not the primary indicator of the drug's success in reducing coronary artery disease risk.
C: Prothrombin time (PT) measures blood clotting efficiency and is unrelated to cholesterol management or atorvastatin's mechanism of action in lipid reduction.
D: Creatine phosphokinase (CK) indicates muscle damage, which may be monitored for side effects of atorvastatin, but CK levels do not measure the drug’s effectiveness in lowering cholesterol.
A client has a new prescription for diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Which information in the client's history is of greatest concern to the nurse in monitoring the client's response to this medication?
Rationale:
Chronic alcoholism is of greatest concern when monitoring a client taking diclofenac. Alcohol use increases the risk of gastrointestinal bleeding and liver toxicity, which NSAIDs like diclofenac can exacerbate. The nurse must be vigilant for signs of adverse effects because combined hepatic strain and mucosal irritation significantly heighten the potential for serious complications during treatment.
A: Migraine headaches do not directly increase the risk of adverse effects from diclofenac, as this medication is often used to treat pain, including migraines.
C: Osteoarthritis is a common indication for NSAIDs like diclofenac, not a concern, since it reflects the condition being treated rather than an increased risk factor.
D: Type 2 diabetes mellitus does not specifically elevate risks associated with diclofenac use; monitoring focuses more on cardiovascular and renal status than this diagnosis alone.
A client with a history of angina reports the onset of chest pain. The nurse determines that the heart rate is 104 beats/minute and the blood pressure is 138/86 mm Hg. A transdermal nitroglycerin patch was applied 30 minutes ago to the right upper chest. Which action should the nurse take?
Rationale:
The nurse should leave the patch in place and administer a PRN dose of sublingual nitroglycerin.
The transdermal patch provides continuous nitrate delivery but acts slowly, so sublingual nitroglycerin is necessary for rapid relief of acute chest pain. The heart rate and blood pressure suggest the client is stable enough for this intervention. Immediate additional patches are not advised due to risk of overdose.
A: Obtain another transdermal patch and position it on the client's left upper chest. Applying a second patch can cause excessive nitrate levels, risking hypotension and worsening symptoms.
C: Withhold further doses of nitroglycerin until contacting the healthcare provider. Delaying sublingual nitroglycerin can prolong ischemic pain and increase heart damage risk without immediate assessment.
D: Reassure the client that the patch will begin to take effect within a few minutes. Transdermal patches have a delayed onset of action, often taking hours, so reassurance alone neglects urgent symptom management.
A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
Rationale:
The nurse should advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately. This ensures the correct medication form is available for safe administration, as low molecular weight heparin syringes are not interchangeable with standard heparin vials for IV use and dosage accuracy is critical for patient safety.
A: Diluting heparin in 250 mL normal saline is inappropriate because pre-filled syringes of low molecular weight heparin are not suitable for IV dilution or administration.
B: Calculating and administering an equivalent dose of low molecular weight heparin is unsafe due to different pharmacokinetics and administration routes compared to standard heparin.
D: Requesting a prescription to change the route and use available heparin bypasses protocol; low molecular weight heparin is not approved for intravenous use in this context.
A male client with a history of heart failure (HF) complains of heartburn when he lies down after dinner. The home health nurse should encourage the client to talk to the healthcare provider about using which over-the-counter medication to relieve this problem?
Rationale:
Low sodium antacid is the best over-the-counter medication for relieving heartburn in a client with heart failure. This option minimizes sodium intake, preventing fluid retention and worsening heart failure symptoms while effectively neutralizing stomach acid to alleviate heartburn discomfort. It balances symptom relief with safety considerations specific to heart failure management, making it the safest choice for this patient.
B: Diphenhydramine is an antihistamine primarily used for allergies and sleep, not heartburn. It does not address acid reflux and may cause sedation or other side effects unrelated to gastrointestinal relief.
C: Low dose aspirin is an antiplatelet agent for cardiovascular protection, not for treating heartburn. Aspirin can irritate the stomach lining, potentially worsening heartburn or causing gastrointestinal bleeding.
D: Acetaminophen is an analgesic and antipyretic used for pain and fever, not acid reflux. It does not neutralize stomach acid or provide relief from heartburn symptoms.
Before administering the initial dose of sumatriptan succinate to a client with a migraine headache, it is most important to determine if the client's history includes which problem? Which problem in the client's history is most important to determine?
Rationale:
Determining if the client has a history of coronary artery disease is most important before administering sumatriptan succinate. Sumatriptan causes vasoconstriction, which can exacerbate coronary artery disease, potentially leading to serious cardiac events. Assessing cardiac history minimizes risk, ensuring safe use. This precaution is critical due to the drug's pharmacological action on blood vessels, particularly coronary arteries.
A: Irritable bowel syndrome involves gastrointestinal symptoms unrelated to sumatriptan’s cardiovascular effects, making it less relevant for assessing risks before administration of this medication.
C: Type 2 diabetes mellitus primarily affects metabolism and blood sugar regulation, not directly impacting the vasoconstrictive action of sumatriptan or increasing immediate cardiac risk.
D: Seasonal allergic rhinitis is an allergic condition affecting nasal passages, unrelated to vascular or cardiac complications associated with sumatriptan use.
The nurse is assessing the client to update the plan of care. Choose the most likely options for the information missing from the statement by selecting from the lists of options provided. The nurse determines that the client is experiencing ___ and the blood pressure changes are the result of ___.
Your Selected Order (Tap items to remove)
Available Options (Tap to select in order)
ASyncope
BHypovolemic shock
CHeart failure
DAdverse drug reaction
EVasodilation
FAntibiotic
GIV infiltration
Rationale:
The nurse determines that the client is experiencing syncope and the blood pressure changes are the result of vasodilation. Syncope involves a temporary loss of consciousness due to reduced cerebral perfusion, often linked to vasodilation, which causes blood vessels to widen, lowering blood pressure and reducing blood flow to the brain, explaining the client’s symptoms and vital sign changes accurately.
B: Hypovolemic shock involves severe fluid loss causing decreased blood volume, which does not align with the transient loss of consciousness or the primary mechanism of vasodilation stated in the scenario.
C: Heart failure is characterized by the heart’s inability to pump effectively, often causing fluid retention and congestion, not sudden syncope due to vasodilation.
D: Adverse drug reaction could cause various symptoms but does not specifically explain syncope combined with vasodilation-induced blood pressure changes.
F: Antibiotic refers to a type of medication, not a cause of syncope or blood pressure changes, thus unrelated to the clinical presentation.
G: IV infiltration denotes fluid leakage into tissues at the IV site, which would cause localized swelling rather than systemic blood pressure changes or syncope.
The nurse is assessing the eyes of a client who just received mydriatic eye drops. Which physiological function of the eye will not respond during the therapeutic period after administration of the eye drops? Which physiological function of the eye will not respond during the therapeutic period after administration of the eye drops?
Rationale:
Pupillary constriction will not respond during the therapeutic period after administration of mydriatic eye drops. Mydriatic drops cause pupil dilation by blocking the parasympathetic pathways responsible for constriction. This effect prevents the pupil from narrowing, which is essential for controlling light entry, thereby temporarily inhibiting the eye’s ability to respond through constriction mechanisms.
A: Accommodation. Accommodation involves lens shape adjustment for focus, which can still occur despite dilation; mydriatics primarily affect pupil size rather than lens flexibility.
B: Refraction. Refraction refers to light bending through the cornea and lens, a passive optical process unaffected by pupil dilation caused by mydriatic drops.
C: Eye convergence. Convergence involves coordinated eye movement for focusing on close objects and remains functional, as mydriatic drops do not impair extraocular muscle control.
The nurse administers risedronate to a client with osteoporosis at 0700. The client asks for a glass of milk to drink with the medication. Which action should the nurse take?
Rationale:
The nurse should instruct the client that it is necessary to take nothing but water with the medication. Risedronate requires administration with plain water to ensure proper absorption and to prevent interactions that can reduce its effectiveness. Milk contains calcium which can bind to the medication, decreasing its bioavailability and therapeutic benefit in treating osteoporosis.
B: Withholding the medication until breakfast delays necessary treatment and risks reduced adherence, as risedronate must be taken on an empty stomach for optimal absorption, not with food.
C: Consulting a pharmacist about dosing one hour after eating neglects that risedronate is best absorbed before meals, and delaying may reduce its efficacy.
D: Assigning UAP to bring low-fat milk ignores the contraindication of calcium interfering with risedronate absorption, potentially compromising the medication’s effectiveness.
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective? Reference Range: Hemoglobin (Hgb) [14 to 18 g/dL (8.7 to 11.2 mmol/L)]
Rationale:
Hemoglobin level increased to 12 g/dL (7.45 mmol/L).
This indicates epoetin alfa’s effectiveness by showing a measurable improvement in anemia, as hemoglobin levels rising toward the normal range signify enhanced red blood cell production. Monitoring hemoglobin is the primary clinical indicator for response to therapy in CKD-related anemia, directly reflecting epoetin alfa’s intended therapeutic action.
A: Food diary shows increased consumption of iron-rich foods. Dietary changes alone do not confirm epoetin alfa’s effectiveness; the medication’s success is measured by hematologic parameters, not nutritional intake.
B: Reports of increased energy levels and decreased fatigue. Subjective symptoms may improve for various reasons, but only objective hemoglobin elevation accurately confirms epoetin alfa’s therapeutic impact.
C: Takes concurrent iron therapy without adverse effects. While iron therapy supports erythropoiesis, tolerating it does not reflect epoetin alfa’s effectiveness or directly measure anemia improvement.
A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD), reports about having difficulty sleeping at night. Which assessment is most important for the nurse to obtain?
Rationale:
The most important assessment is to determine what time the dose is taken. Timing of dextroamphetamine-amphetamine extended-release can significantly impact sleep quality, as taking the medication too late in the day may cause insomnia. Adjusting the administration time can alleviate sleep difficulties without compromising ADHD symptom control, making this assessment critical for managing side effects effectively.
A: Ask about the client's bedtime routine provides helpful sleep hygiene information but does not directly address stimulant-induced insomnia. It overlooks the medication’s pharmacological impact on sleep latency.
B: Inquire about perceived anxiety explores psychological contributors but does not focus on medication timing or stimulant effects, which are more directly linked to sleep disturbances in this context.
D: Determine daily caffeine intake considers stimulant intake but neglects the primary influence of amphetamine dosing time on sleep disruption, making it a less prioritized assessment.
A female client who is starting a new prescription for doxycycline hyclate tells the nurse that she takes birth control pills. Which action should the nurse take?
Rationale:
The nurse should advise the client that the birth control pills will be less effective while taking doxycycline hyclate.
Doxycycline hyclate can reduce the effectiveness of oral contraceptives by interfering with the gut flora responsible for estrogen metabolism, potentially leading to decreased contraceptive efficacy. Informing the client ensures she understands the risk and can use additional contraception methods to prevent unintended pregnancy during antibiotic therapy.
A: Instruct the client to take the two medications at least two hours apart. Timing separation does not prevent the interaction affecting birth control efficacy, as the issue is systemic, not related to absorption timing.
C: Encourage the client to stop taking birth control pills until she has finished taking all the doxycycline hyclate. Discontinuing birth control pills abruptly can lead to unintended pregnancy and is not a recommended or safe action.
D: Notify the healthcare provider of the contraindication to tetracyclines. There is no absolute contraindication between tetracyclines and birth control pills; the concern is decreased contraceptive effectiveness, not a direct contraindication.
A client’s ankle is edematous after an ankle sprain. Which physiological mechanism is responsible for the swelling?
Rationale:
Ankle swelling after a sprain results from histamine-mediated vascular permeability leading to fluid transudation. Histamine increases capillary permeability, allowing plasma proteins and fluid to leak into interstitial spaces, causing edema. This mechanism is a primary inflammatory response to injury, facilitating immune cell access and tissue repair, explaining the characteristic swelling seen in acute ankle sprains.
B: Bradykinin triggers pain and vasodilation but does not primarily cause substance P accumulation, which is more related to neural signaling rather than direct fluid leakage causing edema.
C: Thromboxane A mainly promotes platelet aggregation and vasoconstriction, which limits bleeding rather than increasing vascular permeability or causing swelling in the injured ankle.
D: Neutrophil migration involves immune cell movement to injury sites but does not directly induce the fluid leakage responsible for edema; it is a secondary response following increased permeability.
A client receives a prescription for dextrose 5% in water 500 mL IV to be infused over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Rationale:
The nurse should regulate the infusion at 31 gtt/min.
This calculation uses the formula: (Volume in mL × Drop factor) ÷ Time in minutes. Here, (500 mL × 15 gtt/mL) ÷ 240 minutes equals 31.25, rounded to 31 gtt/min, ensuring precise administration over the prescribed 4-hour period.
29: 29 gtt/min underestimates the infusion rate, leading to slower delivery than prescribed, causing delayed medication effect and potentially compromising patient care.
32: 32 gtt/min results in a faster infusion than ordered, increasing risk of fluid overload or adverse reactions due to exceeding the intended delivery rate.
30: 30 gtt/min slightly slows the infusion, not matching the exact required rate, which can affect therapeutic outcomes by prolonging the administration time beyond 4 hours.
A client with psychosis who is receiving an antipsychotic medication is continually rubbing the back of the neck. Which nursing intervention is best for the nurse to implement? Which nursing intervention is best for the nurse to implement?
Rationale:
The best nursing intervention is to give a PRN prescription for benztropine.
Benztropine is an anticholinergic medication used to treat extrapyramidal symptoms such as muscle stiffness or spasms caused by antipsychotic medications. Rubbing the neck suggests dystonia or muscle discomfort related to medication side effects, making benztropine the appropriate treatment to relieve these symptoms effectively and promptly.
A: Provide the client a heating pad to place on the neck. This may offer temporary comfort but does not address the underlying medication-induced muscle rigidity or dystonia requiring pharmacologic treatment.
B: Obtain a prescription for physical therapy services. Physical therapy is not an immediate solution for medication-induced extrapyramidal symptoms and would delay necessary pharmacologic intervention.
D: Obtain an extra pillow for the client to use at night. An extra pillow may improve comfort during rest but does not alleviate acute muscle symptoms caused by antipsychotic side effects.
A female client with multiple sclerosis reports having less fatigue and improved memory since she began using the herbal supplement, ginkgo biloba. What is the most important information for the nurse to include in the teaching plan for this client?
Rationale:
Ginkgo biloba interacts with aspirin and non-steroidal anti-inflammatory drugs, increasing the risk of bleeding. This interaction is critical for the nurse to address to ensure the client's safety while using the supplement. Understanding medication interactions helps prevent adverse effects, especially in clients with multiple sclerosis who might be on various treatments, making this information essential in the teaching plan.
A: Nausea and diarrhea can occur when using this supplement. This highlights possible side effects but does not address the most critical safety concern related to drug interactions.
B: Ginkgo biloba use should be limited and not taken during pregnancy. While caution during pregnancy is important, it is less relevant for this client unless she is pregnant, focusing less on immediate risks.
D: Anxiety and headaches increase with the use of ginkgo biloba. These symptoms may occur but are less significant compared to the potentially dangerous interactions with blood-thinning medications.
The nurse is preparing the client for discharge and discussing home medications. What home medications may affect the amount of insulin needed by the client? Select all that apply.
Rationale:
St. John’s Wort, corticosteroids, fluconazole, and oral contraceptives may affect the amount of insulin needed by the client. These medications can alter blood glucose levels through various mechanisms, such as inducing or inhibiting enzymes involved in insulin metabolism or impacting insulin sensitivity, thereby necessitating adjustments in insulin dosage to maintain optimal glycemic control and prevent hypo- or hyperglycemia.
D: Ibuprofen does not significantly influence insulin requirements as it primarily acts as a nonsteroidal anti-inflammatory drug without substantial effects on blood glucose regulation or insulin metabolism pathways. Its impact on insulin sensitivity or secretion is minimal and clinically insignificant.
A: St. John’s Wort induces hepatic enzymes, affecting metabolism of insulin and other drugs, leading to altered insulin requirements. It can lower blood glucose by increasing insulin metabolism, requiring careful monitoring during insulin therapy.
B: Corticosteroids increase blood glucose levels by promoting gluconeogenesis and insulin resistance, which raises insulin needs. Their hyperglycemic effect is well-documented and critical in adjusting insulin doses during corticosteroid therapy.
C: Fluconazole inhibits cytochrome P450 enzymes, which can alter insulin metabolism and blood glucose control. This interaction may increase or decrease insulin requirements, depending on individual responses and concurrent medications.
E: Oral contraceptives can cause insulin resistance and elevate glucose levels, increasing insulin needs. Hormonal fluctuations induced by contraceptives necessitate careful monitoring of blood sugar and insulin adjustment during therapy.
A male client who has been taking a high dose of a nonsteroidal anti-inflammatory drug (NSAID) comes to the clinic reporting gastric pain and blood in his stool. The healthcare provider discontinues the NSAIDs and prescribes esomeprazole. Which information should the nurse include in this client's teaching plan?
Rationale:
Notify the healthcare provider of the passage of black stools.
This is essential because black stools may indicate gastrointestinal bleeding, a serious complication of NSAID use. Early detection allows prompt medical intervention. Esomeprazole reduces stomach acid, promoting healing, but ongoing bleeding requires immediate attention. Teaching the client this ensures safety and supports timely communication with healthcare providers to prevent worsening conditions.
A: Call the clinic if diarrhea or headache occur when taking esomeprazole. This focuses on side effects but overlooks critical bleeding signs important in NSAID-induced gastric injury.
B: Once pain subsides, NSAID therapy can be resumed. Resuming NSAIDs prematurely risks further gastric damage and bleeding, ignoring the need for cautious assessment.
C: Resume a diet that consists of milk, cream, and bland foods. This diet is outdated and does not specifically address healing or preventing NSAID-related gastric complications.
A client has a new prescription for diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Which information in the client’s history is of greatest concern to the nurse in monitoring the client’s response to this medication? Which information in the client’s history is of greatest concern to the nurse in monitoring the client’s response to this medication?
Rationale:
Chronic alcoholism is of greatest concern when monitoring a client on diclofenac. This NSAID can exacerbate liver damage and increase the risk of gastrointestinal bleeding, both of which are heightened in clients with alcohol use. The nurse must closely observe liver function tests and signs of bleeding to prevent serious complications.
A: Osteoarthritis primarily involves joint inflammation and pain, which diclofenac is designed to treat, so it does not increase risk factors related to medication side effects.
B: Migraine headaches are unrelated to diclofenac’s primary risks and do not affect the liver or gastrointestinal system, making them a less critical concern.
D: Type 2 diabetes mellitus affects glucose metabolism but does not directly increase the liver toxicity or bleeding risks associated with diclofenac usage.
A client who is newly diagnosed with diabetes insipidus (DI) is receiving a synthetic vasopressin intravenously. Which side effect of vasopressin reported by the client should the nurse report to the healthcare provider?
Rationale:
Worsening headache is a side effect of vasopressin that should be reported to the healthcare provider. Vasopressin can cause vasoconstriction leading to increased blood pressure or cerebral ischemia, potentially resulting in severe headaches, which may indicate serious complications requiring immediate medical attention.
A: Low urine specific gravity reflects concentrated urine, which vasopressin promotes; thus, it is an expected effect, not a concern needing reporting.
B: Polydipsia, or excessive thirst, is a symptom of DI itself, not typically caused by vasopressin administration, so it does not signal an adverse drug effect.
C: Polyuria, or excessive urination, is characteristic of untreated DI; vasopressin usually decreases urine output, making polyuria an unlikely side effect warranting concern here.
After receiving five doses of filgrastim, the nurse notes that the clients white blood cell count has increased from 2,500/mm3 to 5,000/mm3. Which action would the nurse take?
Rationale:
The nurse would inform the client that the medication has been successful.
This response is appropriate because an increase in white blood cell count from 2,500/mm3 to 5,000/mm3 after filgrastim indicates effective stimulation of neutrophil production, reducing infection risk. Communicating this progress reassures the client about treatment efficacy and supports continued adherence to therapy and monitoring for further improvements.
A: Review the client’s culture and sensitivity reports addresses infection management but does not relate directly to the improved white blood cell count indicating successful treatment.
C: Implement neutropenic precautions applies when white blood cell counts are low, not when counts have risen to a safer level after treatment.
D: Assess the clients’ vital signs is routine but does not directly address the significant increase in white blood cell count following filgrastim administration.
A client with eczema receives a prescription for betamethasone cream. Which client statement indicates to the nurse that further teaching is needed?
Rationale:
Applying the cream to the area for 2 weeks indicates that further teaching is needed. Betamethasone cream should not be used for prolonged periods to prevent side effects such as skin thinning and systemic absorption. Typically, treatment duration is limited, and patients must understand proper use to avoid complications associated with extended application beyond recommended guidelines.
A: Use the cream only on intact skin correctly ensures the medication is applied to healthy skin areas, preventing irritation or worsening of eczema on broken or infected skin.
B: Apply the cream to the area for 2 weeks inaccurately suggests a longer treatment duration than recommended, risking side effects from overuse of potent corticosteroids.
C: Cover the site with an occlusive dressing improperly promotes increased absorption and risk of adverse effects, so this statement reveals misunderstanding needing correction.
D: Limit exposure to direct sunlight correctly addresses photosensitivity risks associated with corticosteroids, helping to avoid skin damage and enhancing treatment safety.
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 pg/dL (6 to 47 μmol/dL)]
Rationale:
Serum potassium level of 3.8 mEq/L (3.8 mmol/L). Sodium polystyrene sulfonate is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestine, lowering serum potassium levels. A potassium level within the normal range (3.5 to 5 mEq/L) indicates effective removal of excess potassium, reflecting the medication’s intended action in managing acute kidney injury complications.
A: Serum ammonia level of 30 μg/dL (17.62 μmol/dL) reflects normal ammonia concentration but does not relate to potassium regulation or sodium polystyrene sulfonate’s mechanism of action in AKI management.
B: Hemoglobin level of 13.5 g/dL (135 g/L) is slightly below the reference range and unrelated to potassium balance or the therapeutic impact of sodium polystyrene sulfonate.
D: Serum glucose level of 120 mg/dL (6.7 mmol/L) exceeds the normal glucose range and is unaffected by sodium polystyrene sulfonate, which specifically targets potassium levels, not glucose metabolism.
A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?
Rationale:
A decrease in phosphate indicates that calcium acetate is having the desired effect. Calcium acetate binds dietary phosphate in the gastrointestinal tract, reducing phosphate absorption and lowering serum phosphate levels in patients with chronic kidney disease, thereby preventing hyperphosphatemia and associated complications like bone mineral disorders and vascular calcification.
A: Calcium. Calcium levels typically remain stable or may increase; calcium acetate primarily targets phosphate, not serum calcium reduction.
B: Potassium. Potassium is not directly affected by calcium acetate; its regulation involves different mechanisms and medications in chronic kidney disease management.
D: pH. pH changes relate to acid-base balance, which calcium acetate does not directly influence in treating phosphate retention in CKD patients.
A female client who is starting a new prescription for doxycycline hyclate tells the nurse that she takes birth control pills. Which action should the nurse take?
Rationale:
Doxycycline hyclate can reduce the effectiveness of birth control pills, so the nurse should advise the client about this interaction. This informs the client to use additional contraceptive measures to prevent unintended pregnancy while on doxycycline. Awareness of this interaction promotes safe medication use and helps the client make informed decisions about contraception during antibiotic therapy.
A: Notify the healthcare provider of the contraindication to tetracyclines. This action is unnecessary because doxycycline is not contraindicated with birth control pills; the concern is reduced contraceptive efficacy, not a contraindication.
C: Instruct the client to take the two medications at least two hours apart. Timing separation does not prevent the interaction, as the antibiotic affects hormone metabolism, not absorption, so spacing doses is ineffective.
D: Encourage the client to stop taking birth control pills until she has finished taking all the doxycycline hyclate. Stopping birth control pills abruptly can cause hormonal imbalance and unintended pregnancy risk; discontinuation is unsafe advice.
A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?
Rationale:
A: Monitor for any signs of sexual dysfunction. This statement is appropriate because cimetidine can cause sexual dysfunction as a side effect, so monitoring for these signs is necessary. B: Decrease cigarette use to a pack per day. This requires correction since reducing smoking to a pack still harms ulcer healing; complete cessation is advised. C: Notify the healthcare provider of lethargy. Reporting lethargy is important because it may indicate central nervous system side effects from cimetidine. D: Take the medication an hour after antacids. This is correct since antacids can interfere with cimetidine absorption, so timing the doses an hour apart improves effectiveness.
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Glucose [Reference Range: 74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin (Hgb) [Reference Range: 12-16 g/dL (120-160 g/L)] Potassium (K+) [Reference Range: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Ammonia [Reference Range: Adult: 10 to 80 Mcg/dL (6 to 47 Mcmol/dL)]
Rationale:
Sodium polystyrene sulfonate effectively lowers elevated potassium levels, so a serum potassium level of 3.8 mEq/L indicates the medication has worked. This medication exchanges sodium ions for potassium ions in the intestines, reducing hyperkalemia, which is critical in acute kidney injury management to prevent cardiac complications. Normal potassium reflects successful treatment.
A: Serum ammonia level of 30 Mcg/dL (17.62 Mcmol/dL). Ammonia levels do not reflect sodium polystyrene sulfonate’s effect, as it targets potassium, not ammonia, making this measurement irrelevant to assessing drug efficacy.
C: Serum glucose level of 120 mg/dL (6.7 mmol/L). Glucose concentrations remain unaffected by sodium polystyrene sulfonate, so elevated or normal glucose values provide no indication of the medication's impact.
D: Hemoglobin level of 13.5 g/dL (135 g/L). Hemoglobin levels are unrelated to sodium polystyrene sulfonate treatment, which specifically modulates potassium, not red blood cell indices or oxygen-carrying capacity.
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.) How many mL/hour should the nurse set the infusion pump?
Rationale:
The nurse should set the infusion pump to 37.5 mL/hour.
This calculation is based on the concentration of magnesium sulfate: 4 grams in 500 mL equals 8 mg/mL. To deliver 300 mg/hour, divide 300 mg by 8 mg/mL, resulting in 37.5 mL/hour. This ensures the prescribed dosage is infused accurately over time.
A: 30 mL/hour Delivering 30 mL/hour infuses only 240 mg/hour, which underdoses the patient below the prescribed 300 mg/hour requirement.
B: 40 mL/hour Infusing at 40 mL/hour administers 320 mg/hour, exceeding the prescribed dosage and risking magnesium overdose complications.
C: 50 mL/hour Setting 50 mL/hour results in 400 mg/hour, significantly surpassing the prescribed rate, posing potential toxicity and adverse effects.
A client with chronic lower back pain has been taking ibuprofen PO twice a day for several months. Which assessment is most important for the nurse to complete?
Rationale:
Determine presence of abdominal pain.
Prolonged ibuprofen use increases the risk of gastrointestinal irritation, ulcers, and bleeding, making abdominal pain assessment crucial to identify potential complications early. Monitoring for these symptoms helps prevent serious adverse effects, ensuring patient safety during chronic NSAID therapy. Early detection allows timely intervention, reducing morbidity associated with NSAID-induced GI damage.
B: Palpate volume of pedal pulses assesses peripheral circulation, unrelated to NSAID side effects or chronic lower back pain management.
C: Assessing back pain with a numeric scale gauges pain intensity but doesn’t identify NSAID-related complications requiring urgent attention.
D: Evaluating ongoing sleep patterns monitors pain impact on rest but lacks immediate relevance to potential ibuprofen-induced gastrointestinal issues.
The nurse is teaching a client who has been diagnosed with HIV about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Rationale:
Antiretroviral medication prevents the transmission of the virus. This statement requires additional instruction because while antiretroviral therapy (ART) significantly reduces viral load and transmission risk, it does not completely prevent HIV transmission. Clients need to understand that safe practices remain essential alongside medication to minimize risk. ART controls but does not guarantee absolute prevention of virus spread.
A: The viral load can be decreased to an undetectable level. This accurately reflects ART’s goal to reduce viral load to undetectable levels, lowering disease progression and transmission risk, making it a correct understanding requiring no further instruction.
B: HIV infection is not cured by the antiretroviral regimen. This highlights that ART suppresses HIV but does not eradicate the virus, emphasizing the chronic nature of infection and the need for lifelong treatment, an accurate statement needing no clarification.
C: The medications can decrease acquired AIDS-related complications. This acknowledges that ART helps improve immune function and reduce opportunistic infections, effectively decreasing AIDS-related complications, which is a true statement aligned with treatment goals.
A client is scheduled for a spiral computed topography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client’s history requires follow-up by the nurse?
Rationale:
The client taking metformin hydrochloride for type 2 diabetes requires follow-up due to potential adverse interactions with contrast dye, which can increase the risk of lactic acidosis and acute kidney injury. Monitoring kidney function and possibly withholding metformin before and after the scan is essential to prevent serious complications related to contrast administration in diabetic patients.
A: CT scan performed 6 months earlier does not necessitate immediate nurse follow-up, as prior imaging alone does not contraindicate or complicate the upcoming contrast-enhanced CT scan.
C: Metal hip prosthesis placed two years ago does not interfere with a spiral CT scan or contrast administration, as metal implants are not contraindications for this imaging procedure.
D: A five-year sobriety report is unrelated to contrast use or pulmonary embolism evaluation, having no direct impact on the safety or interpretation of the CT scan results.
The nurse is preparing a client with Chronic Obstructive Pulmonary Disease (COPD) and a chronic productive cough for discharged home. Which prescribed medication should the nurse review with the client to manage this symptom?
Rationale:
Guaifenesin should be reviewed with the client to manage the chronic productive cough. Guaifenesin is an expectorant that helps thin and loosen mucus in the airways, making it easier to cough up and clear secretions. This action directly addresses the symptom of a productive cough in COPD, promoting better airway clearance and respiratory comfort.
A: Salmeterol Long-acting beta-agonist that primarily serves as a bronchodilator for airway relaxation, not specifically targeting mucus production or cough management associated with COPD.
B: Tiotropium Anticholinergic bronchodilator focused on reducing bronchospasm; it does not facilitate mucus clearance or directly alleviate productive cough symptoms.
C: Prednisone A corticosteroid aimed at reducing inflammation, useful in exacerbations but not specifically indicated for managing chronic productive cough or mucus mobilization in COPD patients.
A client who has dysphagia after a cerebral vascular accident (CVA) receives a new prescription for lansoprazole capsules via nasogastric tube (NGT). Which action should the nurse implement prior to administering the medication?
Rationale:
The nurse should mix the capsule granules with water prior to administration. Lansoprazole capsules contain enteric-coated granules that must not be crushed; mixing them with water allows safe delivery via NGT while preserving the medication’s effectiveness and protecting the gastric mucosa. This method ensures proper dissolution and absorption without damaging the drug’s formulation.
B: Request the pharmacist to provide tablets offers no advantage, as tablets may require crushing, risking loss of enteric coating and reducing efficacy when administered via NGT.
C: Open the capsule to crush the granules damages the enteric coating, exposing the drug to gastric acid, which can degrade the medication and diminish its therapeutic effect.
D: Sprinkle the granules in applesauce risks altering the pH environment and may compromise the enteric coating’s integrity, potentially leading to reduced drug efficacy and patient safety concerns.
A patient is currently on an oral contraceptive and has been prescribed erythromycin. What advice should the nurse provide to the patient?
Rationale:
Utilize an additional form of contraception.
Erythromycin can potentially interfere with the effectiveness of oral contraceptives by altering gut flora or liver enzyme activity, reducing hormone absorption or metabolism. Advising the patient to use an additional contraceptive method helps prevent unintended pregnancy during this interaction period, ensuring reliable contraception until the antibiotic course is completed and hormonal levels stabilize.
B: Immediately discontinue the oral contraceptive. This action risks unintended pregnancy and disrupts hormonal balance unnecessarily, as temporary interaction management through additional contraception suffices without stopping the contraceptive.
C: Ensure a 12-hour gap between taking the medications. Timing separation does not prevent erythromycin’s systemic interaction with oral contraceptives, so this advice inadequately addresses the risk of reduced contraceptive efficacy.
D: Avoid prolonged exposure to direct sunlight. This caution relates to photosensitivity with some medications but is unrelated to erythromycin’s effect on oral contraceptive reliability or hormone interaction.
The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Rationale:
Atorvastatin’s desired effect is indicated by a decreased low density lipoprotein (LDL) level. LDL is known as "bad cholesterol" and contributes to plaque buildup in arteries, increasing coronary artery disease risk. Lowering LDL reduces this risk, demonstrating the medication’s effectiveness in managing cholesterol and preventing cardiovascular complications in at-risk clients.
A: High density lipoprotein (HDL) represents "good cholesterol" that helps remove LDL from the bloodstream, but atorvastatin primarily targets lowering LDL, not significantly raising HDL levels as its main therapeutic goal.
C: Creatine phosphokinase (CK) measures muscle damage, not cholesterol levels. Elevated CK might indicate side effects like muscle injury, but it does not reflect atorvastatin’s effectiveness in lowering cardiovascular risk through lipid management.
D: Prothrombin time (PT) assesses blood clotting and coagulation status. It is unrelated to cholesterol or lipid levels, so changes in PT do not indicate atorvastatin’s impact on coronary artery disease risk.
When administering zolpidem to an older client, which computer documentation indicates that the desired outcome has been achieved?
Rationale:
Direct Answer: Sleeps soundly through the night.
Correct Option Explanation: Zolpidem is a sedative-hypnotic medication primarily prescribed to treat insomnia by improving sleep quality. Achieving sound, uninterrupted sleep indicates the medication’s effectiveness in addressing sleep disturbances common in older clients, aligning with the intended therapeutic outcome of promoting restful, sustained sleep without frequent awakenings or insomnia symptoms.
B: Exhibits fewer emotional outbursts relates to mood stabilization, which zolpidem does not target, as it primarily influences sleep patterns rather than emotional regulation or behavioral changes.
C: Improved ability to concentrate concerns cognitive function enhancement, unrelated to zolpidem’s sedative properties focused on inducing and maintaining sleep rather than directly improving mental focus.
D: Decreased episodes of incontinence pertain to urinary control issues, a condition zolpidem does not address, since its pharmacological action centers on sleep induction, not bladder function improvements.
