A nurse is providing an in-service about nonsteroidal anti-inflammatory drugs (NSAIDs) to the unit. Which of the following medications is considered a first-generation NSAID?
Rationale:
Aspirin is considered a first-generation NSAID. First-generation NSAIDs inhibit both COX-1 and COX-2 enzymes, reducing inflammation and pain but increasing gastrointestinal risks. Aspirin’s mechanism exemplifies this, providing anti-inflammatory, analgesic, and antipyretic effects. Unlike second-generation drugs, it does not selectively target COX-2, which distinguishes aspirin as a classic, well-known first-generation NSAID widely used for various inflammatory conditions.
B: Dimenhydrinate is an antihistamine used primarily to prevent nausea and motion sickness, not an NSAID. It lacks anti-inflammatory or COX-inhibiting properties, so it does not fit the criteria for first-generation NSAIDs.
C: Cetirizine is a second-generation antihistamine employed for allergic reactions, without anti-inflammatory effects or COX enzyme inhibition, thus it is unrelated to NSAID classifications.
D: Celecoxib is a second-generation NSAID that selectively inhibits COX-2, minimizing gastrointestinal side effects, which distinguishes it from first-generation NSAIDs like aspirin that inhibit both COX-1 and COX-2.
A nurse is caring for a client who develops an anaphylactic reaction to IV antibiotic administration. After assessing the client's respiratory status and stopping the medication infusion, which of the following actions should the nurse take next?
Rationale:
Administer epinephrine IM is the immediate next action for a client experiencing an anaphylactic reaction.
Epinephrine is the primary, life-saving medication for anaphylaxis due to its potent vasoconstrictor and bronchodilator effects. It quickly counteracts the severe vasodilation, bronchospasm, and laryngeal edema characteristic of anaphylaxis by stimulating alpha and beta-adrenergic receptors. Prompt administration intramuscularly is crucial for stabilizing the client's airway, breathing, and circulation, preventing progression to anaphylactic shock and potential fatality.
B: Elevate the client's legs and feet. Elevating legs might assist with hypotension but critically fails to address the underlying severe immunological reaction or the immediate, life-threatening respiratory compromise characteristic of anaphylaxis, demanding prompt pharmacological intervention.
C: Give diphenhydramine IM. Diphenhydramine is an antihistamine that helps manage skin symptoms like hives and itching but lacks the immediate, life-saving bronchodilatory and vasoconstrictive effects required for severe anaphylaxis.
D: Replace the infusion with 0.9% sodium chloride. While IV fluids might be necessary for hypotension support later, replacing the infusion doesn't address the immediate, life-threatening allergic response or provide the critical pharmacological intervention required.
A nurse is preparing to administer a metered dose inhaler (MDI) medication to a client. Which of the following actions should the nurse take?
Rationale:
Shake the MDI prior to administration.
Shaking the metered dose inhaler (MDI) before use ensures the medication is evenly distributed and properly suspended within the propellant. This crucial step guarantees that each actuated dose contains the intended amount of drug, providing consistent therapeutic effects for the client. Without proper mixing, the client may receive an inadequate or inconsistent dose.
A: Ask the client to inhale the medication quickly for 1 second. A client should inhale slowly and deeply over 3-5 seconds to maximize medication delivery to the lungs. Rapid, short inhalation prevents proper drug deposition, reducing therapeutic benefit.
B: Ask the client to hold their breath for 2 seconds after inhalation. Holding breath for 5-10 seconds after inhalation allows medication particles to settle deeply into the airways. A mere 2-second hold is insufficient for optimal drug absorption and distribution.
D: Wash the MDI canister in warm water after each use. Washing the MDI canister itself is unnecessary and could damage the device or contaminate the medication. Only the mouthpiece or actuator should be cleaned regularly to prevent blockage.
A client diagnosed with strep throat requires antibiotics for treatment. With an allergy to penicillin, the nurse understands which medication should be avoided due to cross-sensitivity with penicillin medications?
Rationale:
Cephalosporins should be avoided due to cross-sensitivity with penicillin medications.
Cephalosporins, structurally similar to penicillins with a beta-lactam ring, pose a risk of cross-hypersensitivity reactions. While newer generations have a lower risk, a client with a documented penicillin allergy, especially a severe one, should generally avoid cephalosporins to prevent potentially life-threatening anaphylaxis or other allergic responses, making careful medication selection crucial for patient safety.
A: Macrolides Macrolides, like azithromycin, have a distinct chemical structure unrelated to penicillin, making them a safe alternative for patients with penicillin allergies, posing no cross-reactivity.
C: Tetracyclines Tetracyclines possess a unique polyketide structure, entirely different from penicillin's beta-lactam ring, thus eliminating any risk of cross-reactivity for allergy sufferers.
D: Sulf
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 ml via intermittent IV bolus over 30 min. The drop factor of the manual IV tubing is 15 gtt/ml. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Rationale:
The nurse should set the manual IV infusion to deliver 50 gtt/min.
To calculate the flow rate in gtt/min, the total volume (100 ml) is divided by the infusion time in minutes (30 min), then multiplied by the drop factor (15 gtt/ml). The calculation is (100 ml / 30 min) 15 gtt/ml, which equals 50 gtt/min. This ensures the medication infuses accurately over the prescribed duration, maintaining therapeutic efficacy.
A nurse is assessing a client who has hypertension and has started taking lisinopril. Which of the following findings should the nurse report to the provider immediately?
Rationale:
Eyelid edema should be reported to the provider immediately. This finding may indicate angioedema, a rare but serious adverse effect of lisinopril that can compromise the airway. Prompt medical intervention is essential to prevent potentially life-threatening complications. Monitoring for swelling around the eyes or face is crucial during ACE inhibitor therapy to ensure patient safety and appropriate treatment adjustments.
A: Nausea is a common, less severe side effect of lisinopril and typically does not require immediate medical attention unless accompanied by other symptoms.
B: Insomnia is unrelated to lisinopril’s major adverse effects and is generally not urgent, often managed with supportive care or lifestyle changes.
C: Dry cough is a frequent side effect of lisinopril but is not an emergency; it usually leads to medication review but does not necessitate immediate reporting.
Aminoglycosides are effective against which strain of bacteria?
Rationale:
Aminoglycosides are effective against Gram-negative bacteria.
Aminoglycosides primarily target Gram-negative bacteria by inhibiting bacterial protein synthesis. These antibiotics bind irreversibly to the 30S ribosomal subunit, disrupting the reading of mRNA and causing premature termination or misreading of amino acids. Their mechanism of action is particularly potent against various aerobic Gram-negative pathogens, making them crucial for treating severe infections.
A: Viral infections Aminoglycosides are antibacterial agents, specifically designed to target bacterial cellular processes. Viruses have different biological structures and replication mechanisms, making them impervious to this class of antibiotics.
B: Gram-positive bacteria While some aminoglycosides may show limited activity against certain Gram-positive organisms, their primary and most significant spectrum of activity is against Gram-negative species. Gram-positive bacteria often possess intrinsic resistance mechanisms.
C: Fungal infections Aminoglycosides exhibit no therapeutic efficacy against fungal pathogens. Fungi are eukaryotes with distinct cellular components and metabolic pathways, rendering them unaffected by the ribosomal inhibition mechanism of these antibacterial drugs.
A nurse is assessing a client who is receiving a peripheral IV infusion and notes infiltration of fluid into the tissues surrounding the insertion site. Which of the following actions should the nurse take?
Rationale:
Elevate the extremity.
Elevating the extremity assists in reducing swelling and promoting fluid reabsorption from the interstitial space back into circulation after IV infiltration. This action leverages gravity to encourage lymphatic and venous drainage, minimizing discomfort and facilitating tissue recovery at the site. It is a primary intervention to manage the localized edema associated with fluid leakage into surrounding tissues.
A: Apply pressure to the IV site. Applying pressure to an infiltrated site would hinder fluid reabsorption and potentially increase localized discomfort, aggravating the existing tissue distension rather than alleviating it.
C: Flush the IV catheter. Flushing an infiltrated catheter would force more fluid into the already compromised interstitial space, worsening the infiltration and increasing tissue swelling and potential damage.
D: Slow the infusion rate. Slowing the infusion rate is insufficient; the primary issue is fluid leakage into tissues, not the rate itself. The catheter must be removed, and the site managed directly.
The nurse is caring for a client who needs to have a peak drug level drawn. The client was given an oral medication 30 minutes ago. What is the best action by the nurse?
Rationale:
Wait for at least another 30 minutes before calling to have the level drawn.
Peak drug levels for oral medications typically occur 1 to 3 hours after administration, as absorption takes time. Drawing the level too early, like at 30 minutes, would not reflect the maximum concentration. Waiting an additional 30 minutes ensures the nurse is closer to the anticipated peak absorption window, allowing for a more accurate assessment of the drug's highest concentration in the bloodstream.
B: Schedule the level to be drawn in 8 hours Scheduling the level 8 hours later would miss the peak concentration entirely, likely reflecting a trough or subtherapeutic level, thus providing inaccurate therapeutic monitoring data.
C: Call the lab to have the medication level drawn immediately Calling for an immediate draw at 30 minutes post-oral administration is premature; the drug has not yet reached its peak absorption, resulting in a falsely low and unrepresentative level.
D: Arrange for the level to be drawn tomorrow since the peak time has passed. The peak
A nurse in a provider's office is assessing a client who has hypothyroidism and has been taking levothyroxine for 2 months. Which of the following statements by the client indicates a therapeutic response to the medication?
Rationale:
I have noticed I'm not as cold as I use to be.
Hypothyroidism often manifests as cold intolerance due to a slowed metabolism and reduced heat production. A therapeutic response to levothyroxine indicates improved thyroid hormone levels, which normalize metabolic processes. The client experiencing less coldness signifies that their body's heat regulation is returning to an optimal state, directly counteracting a primary hypothyroid symptom and confirming medication efficacy.
A: I am taking a laxative for constipation.' Persistent constipation, requiring laxative use, suggests an ongoing manifestation of hypothyroidism. This indicates the medication is not yet fully resolving the gastrointestinal sluggishness associated with inadequate thyroid hormone levels.
C: I am losing weight without dieting.' Unintended weight loss without dietary changes could signal hyperthyroidism or an excessive levothyroxine dose. A therapeutic
A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Rationale:
0.5 tablets should be administered per dose.
To calculate the correct dosage, first convert the available medication from milligrams to micrograms. 0.25 mg is equivalent to 250 mcg. The client requires 125 mcg. Divide the prescribed dose (125 mcg) by the available dose per tablet (250 mcg). This calculation yields 0.5 tablets. Administering this precise
A nurse is reviewing the laboratory results of a client who has liver failure with ascites and is receiving spironolactone. Which of the following findings should the nurse expect?
Rationale:
A nurse should expect a decreased sodium level in a client with liver failure and ascites receiving spironolactone.
Liver failure with ascites commonly leads to dilutional hyponatremia from impaired free
A client has been prescribed diltiazem (Cardizem), and asks the nurse what type of drug this is. Which response by the nurse is most appropriate?
Rationale:
Diltiazem (Cardizem) is a calcium channel blocker.
Diltiazem belongs to the non-dihydropyridine class of calcium channel blockers. It inhibits the influx of extracellular calcium ions across the myocardial and vascular smooth muscle cell membranes. This action leads to a reduction in myocardial contractility, vasodilation, and decreased heart rate, making it effective for treating hypertension, angina, and certain arrhythmias by lowering blood pressure and cardiac workload.
A: A beta blocker. Beta blockers, like metoprolol, selectively or non-selectively block beta-adrenergic receptors, reducing heart rate and contractility. Diltiazem operates through a distinct mechanism, directly affecting calcium channels, not adrenergic receptors.
A nurse is assessing a client who is receiving heparin via continuous IV. The client has an aPTT of 90 seconds. The nurse should monitor the client for which of the following changes in their vital signs?
Rationale:
An increased pulse rate should be monitored in a client receiving heparin with an aPTT of 90 seconds.
An aPTT of 90 seconds indicates a significantly prolonged clotting time, suggesting a high risk of hemorrhage from heparin. Bleeding, especially internal, reduces circulating blood volume, leading to hypovolemia. The body compensates for this decreased volume by increasing the heart rate to maintain adequate cardiac output and tissue perfusion. Therefore, an increased pulse rate is a critical early compensatory sign of potential bleeding.
B: Increased blood pressure. Increased blood pressure is unlikely; significant bleeding typically causes a compensatory drop in blood pressure as blood volume decreases. The body struggles to maintain perfusion.
C: Decreased temperature. Decreased temperature is not a primary or direct indicator of internal bleeding or heparin overdose. Hemorrhage does not typically manifest with hypothermia as an initial vital sign change.
D: Decreased respiratory rate. A decreased respiratory rate is an atypical response to bleeding; the body usually increases respirations to compensate for metabolic acidosis and maintain oxygenation during hypovolemia.
A nurse is reviewing the list of current medications for a client who has a new prescription for nitroglycerin. The nurse should identify that which of the following client medications is contraindicated for use with nitroglycerin?
Rationale:
Sildenafil is contraindicated for use with nitroglycerin.
Sildenafil, a phosphodiesterase-5 inhibitor, causes significant vasodilation. When combined with nitroglycerin, another powerful vasodilator, their synergistic effects can lead to a profound and dangerous drop in blood pressure, resulting in severe hypotension, syncope, or even shock. This interaction is life-threatening, necessitating strict avoidance of concurrent use to prevent cardiovascular collapse.
B: Gemfibrozil Gemfibrozil is a fibrate used for hyperlipidemia. There are no direct or clinically significant drug interactions identified between gemfibrozil and nitroglycerin that would contraindicate their concurrent administration, ensuring patient safety.
C: Lansoprazole Lansoprazole is a proton pump inhibitor primarily used for acid-related conditions. It does not possess any cardiovascular effects or interact with nitroglycerin's vasodilatory mechanism to produce adverse or contraindicated outcomes.
D: Diazepam Diazepam is a benzodiazepine used for anxiety or seizures. While it can cause central nervous system depression, it does not have direct vasodilatory properties or dangerous hemodynamic interactions with nitroglycerin, unlike PDE5 inhibitors.
A nurse is reviewing the health history for a client who has angina pectoris and a prescription for propranolol hydrochloride PO 40 mg twice daily. Which of the following findings in the history should the nurse report to the provider?
Rationale:
The nurse should report that the client has a history of bronchial asthma to the provider.
Propranolol is a non-selective beta-blocker, meaning it blocks both beta-1 and beta
A nurse is caring for a client who is dehydrated and receiving IV fluid replacement. The nurse should identify that which of the following findings indicates the treatment has been effective?
Rationale:
Moist oral mucous membranes indicates the treatment has been effective.
Dehydration causes dry mucous membranes due to fluid deficit. Effective IV fluid replacement rehydrates the body, restoring normal fluid balance. Moist oral mucous membranes are a primary clinical indicator that the body's hydration status has improved significantly, reflecting adequate cellular and interstitial fluid volume. This finding directly demonstrates successful repletion of lost body fluids, confirming treatment efficacy.
A: Decreased blood pressure Dehydration often causes hypotension. Effective rehydration would increase blood pressure towards normal, not decrease it further, indicating worsening hypovolemia or another issue.
B: Excessive thirst Excessive thirst is a cardinal symptom of dehydration, signaling the body's need for fluids. Effective treatment should alleviate this sensation, not exacerbate it, as fluid balance normalizes.
D: Increased heart rate Dehydration typically causes tachycardia as the heart compensates for reduced blood volume. Effective rehydration should decrease the heart rate, returning it to a normal range, not
A nurse is assessing a client who has heart failure and is taking furosemide. Which of the following findings should indicate to the nurse that the client is experiencing fluid volume deficit?
Rationale:
An elevated hematocrit level should indicate to the nurse that the client is experiencing fluid volume deficit.
Furosemide, a potent diuretic, removes excess fluid. An elevated hematocrit level signifies hemoconcentration, where the proportion of red blood cells to plasma increases due to reduced plasma volume. This finding directly reflects a loss of total body water, indicating the client has experienced an excessive therapeutic response to the diuretic, leading to fluid volume deficit.
A: Distended neck veins Distended neck veins are a classic sign of fluid volume excess, indicating increased central venous pressure and systemic fluid overload, not a reduction in circulating volume.
C: Shortness of breath Shortness of breath, especially with heart failure, typically signals fluid accumulation in the lungs (pulmonary congestion), which is a manifestation of fluid volume excess, not a deficit.
D: Weight gain Weight gain directly indicates fluid retention and an increase in total body fluid volume. This finding contradicts fluid volume deficit, which would typically manifest as weight loss.
A nurse is providing teaching for a client who is on diuretic therapy and has a new prescription for potassium chloride (KCL) 20 mEq extended release PO daily. Which of the following instructions should the nurse provide about the new prescription?
Rationale:
Take the extended release tablets whole.
Extended-release medications are formulated to release the drug gradually over an extended period, ensuring stable therapeutic levels and reducing dosing frequency. Crushing, chewing,
A nurse is reinforcing teaching to a client who has a new prescription for imipramine (Tofranil) for treatment of depression. Which of the following should the nurse reinforce in the teaching? (Select all that apply)
Rationale:
Chew sugarless gum to prevent dry mouth and change positions slowly to minimize dizziness are essential teaching points for a client prescribed imipramine.
Imipramine, a tricyclic antidepressant, commonly causes anticholinergic side effects like dry mouth, which sugarless gum can alleviate. Orthostatic hypotension, leading to dizziness upon standing, is another frequent adverse effect, necessitating slow position changes to prevent falls and injury. Reinforcing these strategies helps manage common discomforts and ensures client safety during treatment initiation.
B: Expect therapeutic effects in 24 to 48 hours Therapeutic effects of imipramine typically take several weeks, not days, to manifest fully. Clients should be informed that a significant delay in mood improvement is normal.
C: Decrease dietary fiber intake to control diarrhea Imipramine often causes constipation due to its anticholinergic properties, not diarrhea. Increasing dietary fiber and fluid intake would be more appropriate to manage this common side effect.
D: Discontinue the medication after a week of improved mood Abruptly discontinuing imipramine can lead to withdrawal symptoms and relapse. Clients must continue taking the medication as prescribed, even with improved mood, and consult their provider before any changes.
A client has been diagnosed with allergic rhinitis. Which symptoms would the nurse expect to observe?
Rationale:
The nurse would expect to observe sneezing, watery eyes, nasal congestion, and urticaria in a client diagnosed with allergic rhinitis.
Allergic rhinitis typically manifests with sneezing, a hallmark symptom due to histamine release irritating nasal passages. Watery eyes (lacrimation) occur from conjunctival irritation. Nasal congestion results from inflamed, swollen nasal membranes. Urticaria, or hives, is a systemic allergic reaction sometimes accompanying rhinitis, indicating a broader hypersensitivity response. These symptoms collectively represent the body's reaction to allergens.
A: Wheezing Wheezing primarily indicates lower airway obstruction, typically associated with asthma or other respiratory conditions affecting bronchioles, not a direct symptom of allergic rhinitis which affects the upper respiratory tract.
A nurse is assessing a client who has muscarinic agonist poisoning. Following administration of atropine, which of the following findings should indicate to the nurse that the treatment has been effective?
Rationale:
Heart rate 90/min indicates that the treatment has been effective.
Muscarinic agonist poisoning typically induces bradycardia by overstimulating cardiac muscarinic receptors. Atropine, a competitive
A nurse is teaching a client who has a new prescription for lithium to treat bipolar disorder. The nurse should instruct the client to ensure an adequate intake of which of the following dietary elements?
Rationale:
The nurse should instruct the client to ensure an adequate intake of sodium.
Lithium is a salt that competes with sodium for reabsorption in the kidneys. Maintaining a consistent and adequate sodium intake is crucial because fluctuating sodium levels directly impact lithium excretion and concentration. Low sodium can lead to increased lithium reabsorption and toxicity, while high sodium can decrease lithium levels, reducing therapeutic efficacy. Therefore, consistent sodium intake stabilizes lithium levels.
A: Potassium Potassium intake does not significantly interact with lithium absorption or excretion pathways. While important for general health, potassium levels do not directly influence lithium's therapeutic range or toxicity risk.
B: Vitamin C Vitamin C, an essential antioxidant, holds no direct pharmacological interaction with lithium metabolism or renal clearance. Its dietary presence does not alter the drug's therapeutic effectiveness or potential for adverse effects.
D: Vitamin K Vitamin K is vital for blood clotting, but it has no known physiological or pharmacokinetic relationship with lithium. Its dietary consumption does not impact lithium's absorption, distribution, metabolism, or excretion.
A nurse is preparing to educate a patient who has newly been prescribed sucralfate (Carafate) for the management of peptic ulcer disease (PUD). What is the mechanism of action for this medication?
Rationale:
Creates a protective barrier that adheres to an ulcer, which can stick to the ulcer for up to 6 hours is the mechanism of action for sucralfate (Carafate).
Sucralfate is a cytoprotective agent that forms a viscous, gel-like substance in the acidic environment of the stomach. This substance selectively binds to the positively charged proteins at the base of an ulcer crater, creating a physical barrier. This protective layer shields the ulcer from further damage by acid, pepsin, and bile, promoting healing and preventing irritation for an extended duration.
A: Neutralizes the acidity of the gastric acid. Antacids directly neutralize stomach acid by increasing gastric pH, providing temporary relief but not forming a durable protective barrier like sucralfate.
B: Acts as an endogenous prostaglandin in the GI tract. Misoprostol, a synthetic prostaglandin E1 analog, acts similarly to endogenous prostaglandins, reducing acid secretion and enhancing mucosal protection, a different mechanism entirely.
C: Antagonizes H2 receptors on parietal cells. H2 receptor antagonists like ranitidine or famotidine block histamine's action on parietal cells, thereby decreasing gastric acid production, which differs from sucralfate's localized protective action.
A nurse is caring for a client with a new prescription for alendronate (Fosamax). Which of the following symptoms indicate a possible complication of this medication?
Rationale:
Dysphagia indicates a possible complication of alendronate (Fosamax).
Alendronate, a bisphosphonate, can cause esophageal irritation and ulceration if not taken correctly or if the client lies down too soon after administration. Dysphagia, difficulty swallowing, is a significant symptom indicating potential esophageal damage, such as esophagitis or stricture formation, necessitating immediate medical evaluation. This adverse effect can be severe, impacting client safety and medication adherence due to discomfort.
A: Inflammation on the calf Inflammation on the calf is not a recognized direct adverse effect of alendronate; it might suggest deep vein thrombosis or another localized issue unrelated to this medication's primary side effect profile.
B: Drowsiness Drowsiness is not a typical or expected side effect of alendronate. Clients generally do not experience central nervous system depression from this bisphosphonate, which primarily affects bone metabolism.
D: Nausea Nausea can occur with alendronate, but it is generally considered a common, less severe gastrointestinal upset compared
A nurse is providing teaching to a client Who has a skin infection and a new prescription for gentamicin topical cream. Which of the following instructions should the nurse provide?
Rationale:
Wash the affected area with soap and water before applying cream.
Washing the affected area with soap and water before applying topical gentamicin cream ensures the skin is clean, free from dirt, and any previous medication residue. This preparation facilitates optimal absorption of the antibiotic, allowing it to penetrate effectively and target the infection directly. A clean application site minimizes the risk of further contamination and maximizes the therapeutic efficacy of the medication for localized skin infections.
A: Increase intake of fluids while using this medication
Fluid intake bears no direct correlation with the localized action of topical gentamicin cream. Systemic hydration is not a specific requirement for the proper function or excretion of this externally applied antibiotic.
C: The medication might cause temporary blurred Vision
Blurred vision is not an anticipated adverse effect of topical gentamicin. This medication's localized application for skin infections does not typically lead to systemic absorption sufficient to induce ocular disturbances or visual impairment.
D: Apply the cream to large areas around the infection
Topical gentamicin should be applied precisely to the infected region, as directed, not broadly to extensive surrounding skin. Over-application increases unnecessary exposure, potential irritation, and absorption risk without enhancing treatment efficacy.
A nurse in a clinic sees a client who has an acute asthma exacerbation. Which of the following medications should reduce the symptoms?
Rationale:
Albuterol via jet nebulizer should reduce the symptoms.
Albuterol is a short-acting beta-2 adrenergic agonist (SABA) that provides rapid bronchodilation by relaxing smooth muscles in the airways. Administering it via a jet nebulizer ensures efficient delivery into the lungs, quickly alleviating bronchospasm and improving airflow during an acute asthma exacerbation. This medication is the primary rescue therapy for immediate symptom relief.
A: Budesonide via dry powder inhaler is a corticosteroid used for long-term asthma control and inflammation reduction, not for immediate relief of acute bronchospasm during an exacerbation.
B: Cromolyn via metered dose inhaler is a mast cell stabilizer, primarily used for prophylaxis to prevent asthma attacks, offering no direct bronchodilatory effect for acute symptoms.
D: Montelukast orally is a leukotriene receptor antagonist, prescribed for long-term asthma management and prevention, lacking the rapid onset of action required for acute symptom reduction.
A nurse is teaching a client about cyclobenzaprinWhich of the following client statements should indicate to the nurse that the teaching is effective?
Rationale:
"I will taper off the medication before discontinuing it" indicates effective teaching.
Cyclobenzaprine, a central nervous system depressant, should be gradually tapered to prevent withdrawal symptoms such as nausea, headache, and malaise, and to minimize the risk of rebound muscle spasms. Abrupt cessation can precipitate adverse effects due to its mechanism of action. Effective teaching emphasizes a controlled reduction plan, ensuring client safety and therapeutic continuity, managing dependency potential and symptom recurrence effectively.
A: I will have increased saliva production. Cyclobenzaprine commonly causes anticholinergic effects, which include decreased saliva production (dry mouth), not an increase. This statement reflects a misunderstanding of common side effects.
B: I will continue taking the medication until the rash disappears. A rash could indicate an allergic reaction or severe adverse effect requiring immediate medical evaluation and potential discontinuation, not continued use. This demonstrates a critical safety misunderstanding.
D: I will report any urinary incontinence. Cyclobenzaprine's anticholinergic properties typically cause urinary retention, not incontinence. Reporting incontinence would be less expected than reporting difficulty voiding, indicating a misinterpretation of potential bladder effects.
A nurse is caring for a client who has thrombophlebitis and is receiving a continuous heparin infusion. Which of the following medications should the nurse have available to reverse heparin's effects?
Rationale:
Protamine sulfate should be available to reverse heparin's effects.
Protamine sulfate is the specific antidote for heparin overdose or when rapid reversal of its anticoagulant effects is necessary. It works by forming a stable ion pair with heparin, neutralizing its activity and restoring normal coagulation. Nurses must have it readily accessible to manage potential bleeding complications arising from continuous heparin infusions, ensuring client safety and prompt intervention.
A: Vitamin K: Vitamin K is an antidote for warfarin, not heparin. Warfarin interferes with vitamin K-dependent clotting factors, whereas heparin acts on antithrombin, necessitating a different reversal agent.
B: Deferoxamine: Deferoxamine is a chelating agent used to treat iron toxicity. It possesses no pharmacological action to counteract or reverse the anticoagulant effects induced by heparin.
C: Acetylcysteine: Acetylcysteine serves as an antidote for acetaminophen overdose and also functions as a mucolytic agent. It does not interact with or reverse the anticoagulant properties of heparin.
A nurse is discussing adverse reactions to pain medications in older adult clients with a newly licensed nurse. Which of the following findings should the nurse include as risk factors for an adverse drug reaction? (Select all that apply)
Rationale:
Multiple health problems, polypharmacy, and decreased renal function are risk factors for adverse drug reactions in older adult clients.
Older adults often experience physiological changes increasing drug sensitivity. Multiple health problems create complex health states, necessitating various medications that can interact adversely. Polypharmacy, the use of multiple drugs, significantly elevates interaction risks and side effects. Furthermore, age-related decreased renal function impairs drug excretion, leading to higher plasma concentrations and prolonged drug half-lives, thereby intensifying the likelihood of experiencing adverse drug reactions.
A: Decreased percentage of body fat. Older adults typically have an increased percentage of body fat, not decreased. This alters drug distribution, especially for lipid-soluble drugs, potentially prolonging their effects and increasing adverse reactions, making "decreased" an incorrect statement.
C: Increased rate of absorption. Aging generally leads to a decreased rate of drug absorption due to reduced gastrointestinal motility and blood flow. An increased rate would typically lead to quicker onset but not necessarily increased risk of adverse reactions in the context of prolonged exposure.
A nurse in a provider's office is assessing a client who has hypothyroidism and has been taking levothyroxine for 2 months. Which of the following statements by the client indicates a therapeutic response to the medication?
Rationale:
I have noticed I'm not as cold as I use to be.
This statement indicates a therapeutic response because cold intolerance is a hallmark symptom of hypothyroidism. Levothyroxine therapy aims to restore thyroid hormone levels
When using the antitussive Benzonatate, also known as Tessalon Pearls, it is very important to teach the patient to
Rationale:
Swallow whole and do not bite or chew the medication.
Benzonatate pearls contain liquid medication that, if released prematurely by chewing or biting, can numb the mouth and throat. This localized anesthetic effect can lead to choking or aspiration due to impaired swallowing reflexes. Therefore, ingesting the capsule intact ensures the medication's intended systemic absorption and prevents adverse oral or pharyngeal numbing, safeguarding the patient from potential respiratory complications.
A: Eat a high-fatty meal prior to taking medication. Benzonatate absorption is not significantly influenced by dietary fat intake. Administering it with a high-fat meal offers no therapeutic advantage and is not a recommended instruction for safe or effective drug delivery.
B: Medication can be taken often and whenever he feels a cough is starting. Benzonatate has a specific dosing regimen, typically three times daily, and exceeding this frequency increases the risk of adverse effects. Overuse does not enhance antitussive action but elevates toxicity potential.
D: Take medication with orange juice. Orange juice, being acidic, does not interfere with Benzonatate's stability or absorption. However, there is no specific instruction or therapeutic benefit associated with consuming this medication alongside orange juice.
A nurse is providing teaching to a client who has a new diagnosis of Parkinson's disease. On which of the following medications should the nurse prepare to instruct the client?
Rationale:
Levodopa/carbidopa is the medication on which the nurse should prepare to instruct the client.
Levodopa/carbidopa is a primary treatment for Parkinson's disease, addressing motor symptoms like bradykinesia and rigidity. Levodopa converts to dopamine in the brain, replenishing deficient levels, while carbidopa prevents its peripheral breakdown, ensuring more reaches the brain and reducing side effects. This combination significantly improves quality of life for clients with a new Parkinson's diagnosis by managing debilitating symptoms.
A: Carbamazepine is an anticonvulsant and mood stabilizer primarily used for epilepsy and trigeminal neuralgia. Its pharmacological action does not target the dopamine deficiency or motor symptoms characteristic of Parkinson's disease, making it an inappropriate therapy.
B: Piperacillin/tazobactam is a broad-spectrum antibiotic combination prescribed for severe bacterial infections. This medication
A nurse is administering naloxone to a client who has developed an adverse reaction to morphine. The nurse should identify which of the following findings as a therapeutic effect of naloxone?
Rationale:
Naloxone produces an increased respiratory rate as a therapeutic effect by reversing opioid-induced respiratory depression. It acts as an opioid antagonist, rapidly restoring normal breathing in clients affected by morphine overdose, thereby preventing hypoxia and other serious complications associated with opioid toxicity.
A: Decreased nausea does not directly result from naloxone administration; it primarily targets opioid receptors to reverse respiratory depression rather than gastrointestinal symptoms.
C: Decreased blood pressure is not a therapeutic effect of naloxone; it mainly counteracts opioid effects without significantly altering blood pressure levels.
D: Increased pain relief contradicts naloxone’s purpose since it reverses opioid effects, potentially reducing analgesia rather than enhancing it.
A nurse is teaching a group of students about the components of informed consent. Which of the following should the nurse include?
Rationale:
The alternative treatments to the procedure should be explained.
Informed consent mandates a comprehensive understanding of the proposed treatment. This includes a detailed discussion of all viable alternative treatments or procedures, along with their potential risks and benefits. Clients must possess complete information regarding all available options, enabling them to make an autonomous, well-reasoned decision about their healthcare. This ensures the client's decision is truly informed and voluntary, reflecting full disclosure.
A: The client cannot change their mind after signing consent. Clients retain the absolute right to withdraw consent at any point, even after signing the form and before the procedure begins. Consent is an ongoing process, not a one-time, irreversible event.
C: The time of the procedure should be indicated on the form. While the procedure's name and date are typically recorded, the exact time is not a mandatory component of the informed consent
A nurse is assessing a patient with activity intolerance for possible orthostatic hypotension. Which finding will help confirm orthostatic hypotension?
Rationale:
BP sitting 130/60; standing 110/60 will help confirm orthostatic hypotension.
This reading confirms orthostatic hypotension because the systolic blood pressure drops by 20 mmHg (from 130 to 110 mmHg) upon standing, meeting the diagnostic criterion. This significant reduction in systemic pressure indicates the body's inability to adequately compensate for gravitational pooling of blood, often leading to symptoms like dizziness or lightheadedness in individuals with activity intolerance.
A: BP sitting 140/60; standing 130/50 This option shows a systolic drop of only 10 mmHg and a diastolic drop of 10 mmHg, which is not sufficient for a clear systolic diagnosis of orthostatic hypotension by common criteria.
C: BP sitting 126/64; standing 120/58 This reading displays a minimal systolic drop of 6 mmHg and a diastolic drop of 6 mmHg, neither of which meets the established criteria for orthostatic hypotension.
D: BP sitting 130/64; standing 140/70 This patient's blood pressure actually increases upon standing, indicating a compensatory response rather than the characteristic drop associated with orthostatic hypotension.
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Rationale:
The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking Calcium.
Calcium supplements are known to significantly impair the absorption of levothyroxine in the gastrointestinal tract. This interaction can reduce the thyroid hormone's effectiveness, necessitating a separation period to ensure adequate drug uptake. Waiting at least 4 hours between levothyroxine and calcium administration minimizes this binding interference, optimizing the client's thyroid hormone replacement therapy.
A: Ginkgo biloba Ginkgo biloba primarily affects platelet aggregation and cerebral blood flow, posing no direct or significant interference with levothyroxine absorption requiring a 4-hour separation.
C: Vitamin C Vitamin C can actually enhance levothyroxine absorption by lowering gastric pH and and improving solubility, thus it does not require a delayed administration.
D: Zinc While
Which of the following medications is an inhaled agent used for long-term prophylaxis of asthma?
Rationale:
Beclomethasone (QVAR) is an inhaled agent used for long-term prophylaxis of asthma.
Beclomethasone (QVAR) is an inhaled corticosteroid, a cornerstone medication for asthma prophylaxis. It reduces airway inflammation over time, preventing exacerbations and controlling symptoms. Administered via inhalation, it delivers the anti-inflammatory effect directly to the lungs, minimizing systemic side effects. This makes it highly effective for long-term management and maintenance therapy in persistent asthma, improving lung function and quality of life.
B: Metoprolol. Metoprolol is a beta-blocker primarily used for hypertension and cardiac conditions; it can actually worsen asthma by causing bronchoconstriction, making it unsuitable for asthmatic patients.
C: Phenytoin. Phenytoin is an anticonvulsant medication prescribed for epilepsy and seizure disorders; it has no therapeutic role in the management or prevention of asthma symptoms.
D: Furosemide. Furosemide is a potent loop diuretic used to treat edema and hypertension; it does not possess any bronchodilatory or anti-inflammatory properties relevant to asthma treatment.
A nurse is assessing a client who is receiving penicillin IV. For which of the following findings should the nurse report to the provider as a manifestation of anaphylaxis?
Rationale:
Wheezing is a manifestation of anaphylaxis that the nurse should report to the provider.
Wheezing signifies bronchospasm and laryngeal edema, characteristic respiratory symptoms of anaphylaxis. This acute, severe allergic reaction to
A nurse is reviewing a provider's prescriptions for medications. Which of the following prescriptions should the nurse clarify with the provider?
Rationale:
Lisinopril 5.0 mg PO once daily should be clarified with the provider.
The prescription for Lisinopril 5.0 mg PO once daily requires clarification due to the trailing zero after the decimal point. Using "5.0 mg" instead of simply "5 mg" creates a significant risk of misinterpretation; the decimal point could be overlooked, leading to an accidental ten-fold overdose (50 mg). Nurses
A nurse is providing teaching to a school-age child who has a new diagnosis of type 1 diabetes mellitus. Which of the following statements by the child indicates an understanding of the teaching?
Rationale:
My morning blood glucose should be between 90 and 130.
This statement demonstrates understanding of target blood glucose levels for school-age children with type 1 diabetes. Maintaining blood glucose within the specified range (90-130 mg/dL pre-meal, often used for morning readings) is crucial for preventing both hyperglycemia and hypoglycemia, ensuring optimal health and glycemic control. Understanding these targets empowers the child to actively participate in managing their condition effectively, promoting long-term well-being.
A: I should eat a snack half an hour before playing soccer. This timing is too late; a child should consume a snack 30-60 minutes before exercise to prevent hypoglycemia, or even during prolonged activity, not just 30 minutes prior.
B: I should not take my regular insulin when I am sick. Illness often increases blood glucose, necessitating continued or even increased insulin doses, never withholding it, to prevent diabetic ketoacidosis.
D: I can store unopened bottles of insulin in the freezer. Freezing insulin destroys its protein structure, rendering it ineffective, so it must be refrigerated, never frozen, before opening.
A patient complains of worsening nasal congestion despite the use of oxymetazoline (Afrin) nasal spray every 2 to 4 hours for the past 5 days. The nurse's response is based on the knowledge that
Rationale:
Sustained use of nasal decongestants over several days may result in rebound congestion.
Oxymetazoline, an alpha-adrenergic agonist, constricts nasal blood vessels, reducing congestion. However, prolonged
A client has been prescribed an antibiotic and overhears the prescriber talking about acquired resistance. The client asks the nurse what this means. What is the nurse's best statement regarding acquired resistance?
Rationale:
Refers to an infection that is resistant to conventional antibiotics.
Acquired resistance describes when microorganisms, initially susceptible to an antibiotic, develop the ability to withstand its effects over time. This happens through genetic mutations or horizontal gene transfer, allowing bacteria to survive and multiply even in the presence of the drug. Consequently, standard antibiotic treatments become ineffective against these resistant strains, making infections harder to treat and posing a significant public health challenge.
B: Superinfection that has significant antifungal resistance Superinfection relates to a new infection occurring during or after treatment for a primary one, often involving different pathogens, and does not specifically define the mechanism of acquired antibiotic resistance.
C: Refers to a term used for antibiotic coverage Antibiotic coverage describes the range of pathogens an antibiotic is effective against, not the process by which bacteria become resistant to previously effective treatments.
D: There is no such phenomenon of acquired resistance Acquired resistance is a well-documented and significant global health issue, where pathogens evolve mechanisms to evade antimicrobial agents, rendering treatments ineffective.
The nurse is reviewing the food choices of a patient who is taking a monoamine oxidase inhibitor (MAOI). Which food choice would indicate the need for additional teaching?
Rationale:
Pepperoni pizza would indicate the need for additional teaching.
Pepperoni is a fermented and aged meat product, making it exceptionally high in tyramine. Consuming tyramine-rich foods while taking a monoamine oxidase inhibitor (MAOI) can precipitate a life-threatening hypertensive crisis due to the inhibited breakdown of tyramine. The nurse must immediately intervene to educate the patient on avoiding such dangerous dietary selections to ensure patient safety and prevent adverse drug reactions.
A: Egg salad sandwich Eggs, mayonnaise, and standard bread components are low in tyramine. This meal poses no significant risk for a patient on MAOI therapy, making it a safe dietary choice.
C: Pancakes and maple syrup Pancakes and maple syrup are generally devoid of tyramine. This breakfast option is considered safe for individuals prescribed monoamine oxidase inhibitors, requiring no specific dietary precautions.
D: Fried eggs over
A nurse is caring for a client who started haloperidol five days ago and is experiencing neuroleptic malignant syndrome. Which of the following prescriptions should the nurse anticipate administering?
Rationale:
The nurse should anticipate administering Bromocriptine.
Bromocriptine is a dopamine agonist, crucial for treating neuroleptic malignant syndrome (NMS) by restoring dopamine activity in the central nervous system. NMS is characterized by severe muscle rigidity, fever, and autonomic dysfunction, often caused by dopamine receptor blockade from antipsychotics like haloperidol. Increasing dopamine levels helps alleviate these severe symptoms, making it a primary pharmacological intervention for NMS.
A: Benztropine Benztropine is an anticholinergic medication primarily used to treat extrapyramidal symptoms like dystonia or akathisia, not the severe hyperthermia and muscle rigidity characteristic of neuroleptic malignant syndrome.
B: Naloxone Naloxone is an opioid antagonist used to reverse opioid overdose effects. It holds no therapeutic value in managing the complex pathophysiology of neuroleptic malignant syndrome, which is related to dopamine blockade.
D: Diphenhydramine Diphenhydramine, an antihistamine with anticholinergic properties, might be used for mild extrapyramidal symptoms. However, it is ineffective for the life-threatening muscle rigidity, hyperthermia, and autonomic instability seen in neuroleptic malignant syndrome.
A nurse in a provider's office is assessing an older adult client whose son reports that the client has been sick with a respiratory illness for the past 6 days. Which of the following assessment findings is a manifestation of pneumonia in the older adult client?
Rationale:
Confusion is a manifestation of pneumonia in the older adult client.
Older adults often present with atypical signs of pneumonia due to blunted immune responses and pre-existing cognitive decline. Instead of classic fever or cough, acute confusion or delirium frequently becomes the primary indicator of infection, including respiratory illnesses like pneumonia. This sudden change in mental status signifies systemic stress and compromised oxygenation, making it a critical assessment finding for nurses evaluating elderly clients with suspected pneumonia.
A: Narrowed pulse pressure
Narrowed pulse pressure typically indicates conditions like aortic stenosis or hypovolemic shock, not a direct manifestation of pneumonia. It doesn't reflect the respiratory infection itself.
B: Bradycardia
Bradycardia, a slow heart rate, is generally not a typical
A nurse is preparing to administer total parenteral nutrition to a client. Which of the following actions should the nurse take?
Rationale:
Keep the solution refrigerated until 1 hr before infusion is the correct action a nurse should take when preparing to administer total parenteral nutrition.
TPN solutions are sensitive and require refrigeration to maintain their stability and prevent bacterial growth. Bringing the solution to room temperature for approximately one hour before infusion helps prevent venous irritation and discomfort for the client. This preparation ensures the nutritional components remain effective and safe for intravenous administration, optimizing client tolerance and therapeutic outcomes throughout the infusion period.
A: Obtain the client's weight three times a week. Daily weight monitoring is crucial for assessing fluid balance and nutritional status in clients receiving TPN, making three times a week insufficient for accurate assessment.
B: Check the client's WBC count daily. While infection is a risk, daily WBC checks are not standard TPN protocol unless infection is suspected. Routine monitoring focuses more on glucose and electrolytes.
D: Change the solution every 36 hr. TPN solutions are typically changed every 24 hours to minimize the risk of bacterial contamination and maintain solution integrity, not every 36 hours.
A nurse is providing discharge teaching to a client who has asthma and a new prescription for fluticasone/salmeterol. For which of the following adverse effects should the nurse instruct the client to report to the provider?
Rationale:
A nurse should instruct the client to report a white coating in the mouth to the provider.
Fluticasone, an inhaled corticosteroid component of this medication, suppresses local immune responses in the oral cavity. This creates an environment conducive to the overgrowth of Candida albicans, leading to oral candidiasis, commonly known as thrush. This fungal infection manifests as a white coating and requires medical attention, often antifungal treatment, making it an important adverse effect to report promptly to the provider.
A: Increased appetite This is not a typical or reported adverse effect of fluticasone/salmeterol, which primarily acts locally in the airways with minimal systemic absorption affecting appetite regulation.
B: Dry oral mucous membranes While some medications can cause xerostomia, dry mouth is not a prominent or concerning adverse effect specifically associated with inhaled fluticasone/salmeterol requiring provider notification.
D: Sedation This medication combination is designed to open airways and reduce inflammation, not to induce central nervous system depression or drowsiness, making sedation an unexpected and unrelated symptom.
A nurse is caring for a client who is in shock and is receiving an infusion of albumin. Which of the following findings should the nurse expect?
Rationale:
An increase in BP is the finding the nurse should expect.
Albumin, a colloid, expands plasma volume by increasing oncotic pressure, drawing interstitial fluid into the vascular space. This augmented circulating volume enhances venous return and cardiac output. Consequently, improved perfusion to vital organs directly elevates systemic vascular resistance and blood pressure, counteracting the hypovolemic state characteristic of shock and indicating therapeutic effectiveness.
A: PaCO2 30 mm Hg This value suggests respiratory alkalosis, often due to hyperventilation in early shock. However, albumin directly addresses circulating volume and blood pressure, not primarily altering respiratory gas exchange parameters as its main expected effect.
B: Oxygen saturation 96 An oxygen saturation of 96% is within the normal range. While improved circulation from albumin can enhance tissue oxygenation, this specific value doesn't represent a unique change or primary expected outcome directly reflecting albumin's immediate
A nurse is providing discharge teaching about warfarin to a client who has deep-vein thrombosis. The nurse should instruct the client to obtain which of the following laboratory tests monthly?
Rationale:
The client should obtain an INR laboratory test monthly.
Warfarin is an anticoagulant that inhibits vitamin K-dependent clotting factors. The International Normalized Ratio (INR) is the standard laboratory test used to monitor the therapeutic effect of warfarin, ensuring the client's blood is adequately thinned to prevent further clot formation while minimizing bleeding risk. Regular monthly monitoring of INR is crucial for safe and effective anticoagulation management and dose adjustment.
A: Platelet count Platelet count assesses the number of platelets, which are crucial for primary hemostasis. Warfarin primarily affects clotting factors, not platelet production or function, making platelet count monitoring irrelevant for its therapeutic efficacy.
B: aPTT The activated partial thromboplastin time (aPTT) monitors the intrinsic and common pathways of coagulation, primarily used for unfractionated heparin therapy. Warfarin's effects are better assessed by the extrinsic pathway, reflected in the INR.
D: Fibrinogen Fibrinogen is a clotting protein essential for clot formation. While important in coagulation, warfarin's direct impact on its levels isn't the primary measure for therapeutic monitoring, as INR provides a more comprehensive assessment of anticoagulation.
