A client is admitted to the emergency department with fever, chills, and severe left costovertebral pain. Which diagnostic test should be prioritized to evaluate the underlying cause of these symptoms?
Rationale:
Urinalysis with culture should be prioritized to evaluate the underlying cause of fever, chills, and severe left costovertebral pain. This test detects urinary tract infections or pyelonephritis, which commonly present with these symptoms. Identifying bacteria and their antibiotic sensitivity guides appropriate treatment, making it essential for timely and accurate diagnosis in suspected renal infections.
A: Complete blood count (CBC) reveals general signs of infection or inflammation but cannot specifically identify urinary pathogens or localize the infection to the renal system, limiting its diagnostic precision here.
C: Chest X-ray assesses lung pathology, unrelated to costovertebral pain or urinary tract infection, thus providing irrelevant information for the presenting symptoms.
D: CT scan of the abdomen and pelvis offers detailed imaging but is typically reserved for complicated cases or when initial tests fail to clarify diagnosis, not as the initial evaluation step.
A client's insulin dosage is 16 units of regular insulin in the morning. The client should be taught to expect the insulin peak within:
Rationale:
The client should expect the insulin peak within 2 to 4 hours. Regular insulin typically reaches its peak action between 2 and 4 hours after administration, which helps manage blood glucose levels effectively during this period. Understanding this timing allows clients to monitor for hypoglycemia and adjust food intake accordingly, ensuring safe and optimal insulin therapy outcomes.
B: 12 to 16 hours refers to the duration of long-acting insulin, not the peak time of regular insulin. This timeframe mismatches the rapid action phase required for mealtime glucose control.
C: 3 to 10 hours extends beyond the typical peak, overlapping with the insulin’s tail end instead of its peak action, which usually occurs earlier.
D: 2 to 8 hours is too broad, diluting the precise peak window. It lacks specificity, potentially leading to misinterpretation of the insulin’s peak action timing.
A client is scheduled to receive atenolol 25 mg PO and diltiazem 60 mg PO at 0800. The nurse assesses the client's heart rate as 45 beats/minute and irregular. What is the best nursing action at this time?
Rationale:
The best nursing action is to hold the atenolol and administer the diltiazem.
Atenolol, a beta-blocker, and diltiazem, a calcium channel blocker, both lower heart rate. With a heart rate of 45 bpm and irregular rhythm, administering both could cause severe bradycardia or heart block. Holding atenolol reduces risk while still providing necessary medication, ensuring patient safety and preventing further cardiac complications.
A: Document the pulse rate and administer the medications as prescribed The heart rate is dangerously low and irregular, posing risk if both drugs are given; documentation alone neglects immediate safety concerns.
B: Assess for chest pain and administer atenolol if pain free Chest pain assessment doesn’t address bradycardia; giving atenolol with a low heart rate risks worsening cardiac depression regardless of pain presence.
D: Withhold the medications and reassess the heart rate in 30 minutes Waiting may delay critical intervention; withholding both drugs without assessing the necessity of each medication could risk imbalance in cardiac management.
A nurse is caring for a client who is 1 hr postpartum and observes a large amount of lochia rubra and several small clots on the client's perineal pad. The fundus is midline and firm at the umbilicus. Which of the following actions should the nurse take?
Rationale:
Document the findings and continue to monitor the client. This action is appropriate because the fundus is firm and midline at the umbilicus, indicating effective uterine contraction. Lochia rubra with small clots is expected within the first hour postpartum. Monitoring ensures early detection of any changes without unnecessary interventions, supporting safe, evidence-based nursing care.
A: Notify the client's provider. Immediate provider notification is unnecessary since the fundus is firm and midline, and lochia rubra with small clots is normal at one hour postpartum.
B: Encourage the client to empty her bladder. Bladder emptying is not required here because the fundus is already firm and midline, showing no displacement or retention effects.
C: Increase the frequency of fundal massage. Additional fundal massage is not needed as the uterus is firm, and excessive massage could cause discomfort or trauma.
The nurse is caring for a client diagnosed with amyotrophic lateral sclerosis (ALS). The client was given a medical prescription for tizanidine. What information would the nurse provide regarding this medication? Tizanidine is
Rationale:
Tizanidine is a muscle relaxant medication used to reduce muscle spasms. This medication acts on the central nervous system to relieve spasticity commonly experienced by clients with ALS, improving comfort and mobility. It helps decrease muscle stiffness and involuntary contractions, which are frequent symptoms in ALS, thereby enhancing the client’s quality of life and functional abilities.
A: a sleep aid and used to promote sleep along with melatonin. This option inaccurately describes tizanidine, which primarily targets muscle spasticity rather than inducing or improving sleep patterns.
C: an antibiotic medication used to treat bacterial infections. Tizanidine does not possess antibacterial properties and is unrelated to infection management, focusing instead on neurological symptom relief.
D: an opiate and is used to relieve severe pain. Tizanidine is not an opioid; it does not function as a painkiller but as a muscle relaxant to reduce spasticity in neurological conditions.
A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?
Rationale:
Hyperkalemia is the electrolyte imbalance expected in a client with prerenal acute kidney injury (AKI). Prerenal AKI reduces kidney perfusion, impairing potassium excretion and causing potassium to accumulate in the blood. This leads to elevated serum potassium levels, a hallmark finding in prerenal AKI. Monitoring potassium is critical to prevent cardiac complications associated with hyperkalemia.
A: Hypercalcemia Elevated calcium levels are not typically seen in prerenal AKI; kidney hypoperfusion primarily affects potassium handling rather than calcium regulation, making hypercalcemia unrelated to this condition’s typical electrolyte disturbances.
B: Hypernatremia Excess sodium is uncommon in prerenal AKI since the kidneys usually retain sodium to compensate for hypoperfusion, often resulting in normal or low sodium levels instead of hypernatremia.
C: Hypophosphatemia Phosphate levels typically increase or remain normal in AKI due to decreased renal excretion; hypophosphatemia does not align with the impaired kidney function characteristic of prerenal AKI.
A nurse is caring for a client who has a prescription for clopidogrel. Which of the following actions should the nurse plan to take?
Rationale:
Monitor the client for black, tarry stools. Clopidogrel is an antiplatelet medication that increases the risk of bleeding, particularly gastrointestinal bleeding. Black, tarry stools can indicate occult blood loss, so careful monitoring helps detect early signs of bleeding complications and ensures timely intervention, promoting client safety and preventing severe adverse effects.
A: Initiate contact precautions. Contact precautions are used to prevent infection transmission, not related to clopidogrel use. This medication does not increase infectious risk, so these measures are unnecessary for this client.
C: Administer the medication with each meal. Clopidogrel absorption does not depend on food intake, so timing with meals is not critical. This action does not specifically enhance safety or effectiveness.
D: Have suction equipment at the bedside. Suction equipment is generally for airway management, not routinely required for clients on clopidogrel unless there is a high risk of bleeding causing airway obstruction.
A nurse receives an order from the provider for a client requiring the highest oxygen concentration with a one-way valve. What type of mask should the nurse apply to the client?
Rationale:
A non-rebreather mask provides the highest oxygen concentration with a one-way valve. This mask delivers nearly 100% oxygen by preventing exhaled air from mixing with the oxygen supply, ensuring maximum oxygen delivery. The one-way valves stop room air entry and direct exhaled gases out, making it ideal for clients needing high oxygen concentrations in critical situations.
A: Simple face mask delivers moderate oxygen levels without one-way valves, allowing room air to dilute oxygen concentration, making it unsuitable for highest oxygen delivery needs.
B: Venturi mask provides precise oxygen fractions but uses adapters, not one-way valves, and does not deliver the highest oxygen concentrations.
D: Partial rebreather mask has no one-way valves, allowing some exhaled air to be rebreathed, thus not achieving the highest oxygen concentration.
The nurse must administer 1600 mL of total parenteral nutrition (TPN) over 24 hours. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest tenth, do not use trailing zeros, use a leading zero if it applies)
Rationale:
The nurse should set the IV pump to deliver 66.7 mL/hr.
This rate results from dividing the total volume of 1600 mL by 24 hours, yielding approximately 66.6667 mL/hr, which rounds to 66.7 mL/hr. This ensures the TPN is infused evenly over the entire 24-hour period, maintaining consistent nutrient delivery and avoiding complications from rapid or delayed infusion.
A: 66 mL/hr This value underestimates the exact rate, potentially causing incomplete infusion within 24 hours, risking inadequate nutrition and patient harm due to slower-than-required administration.
B: 160 mL/hr This rate is too high, which would infuse the TPN solution much faster than the prescribed 24-hour period, possibly leading to fluid overload or metabolic imbalances.
C: 6.7 mL/hr This rate dramatically under-delivers the volume, extending infusion time far beyond 24 hours and failing to provide necessary nutrients in the correct timeframe.
D: 600 mL/hr Delivering at 600 mL/hr would complete the infusion in less than three hours, which is unsafe and inconsistent with the 24-hour prescription, risking adverse patient outcomes.
A nurse is providing care for a client diagnosed with diabetic ketoacidosis (DK
Rationale:
A, B, C, and E are appropriate interventions for clients at risk of or experiencing complications related to diabetic ketoacidosis (DKA). Exercise, elevation of legs, intermittent pneumatic compression pumps, and layered wraps all help improve circulation and prevent complications such as deep vein thrombosis and edema, which are common concerns in immobile or critically ill patients.
D: Ankle-brachial index test assesses peripheral artery disease but does not provide direct therapeutic benefits for DKA management or prevention of its complications.
A nurse is reviewing orders for a patient in anaphylactic shock. Which medication should the nurse plan to administer first?
Rationale:
Epinephrine (Adrenaline) should be administered first to a patient in anaphylactic shock. Epinephrine rapidly reverses airway obstruction, hypotension, and shock by vasoconstriction, bronchodilation, and stabilizing mast cells. It is the primary life-saving treatment in anaphylaxis, making it essential for immediate intervention before other supportive measures or medications are considered.
A: Glucose Dextrose Oral (GDO) does not address airway compromise or cardiovascular collapse in anaphylaxis and is unrelated to emergency management of shock or allergic reactions.
C: Dexamethasone (Decadron) serves as a secondary anti-inflammatory agent and does not provide the immediate life-saving effects needed in acute anaphylaxis.
D: 0.9% Normal Saline helps maintain blood pressure but does not reverse airway obstruction or allergic mediator release, making it insufficient as the initial treatment.
Which of the following is the most common risk factor for emphysema?
Rationale:
Smoking tobacco is the most common risk factor for emphysema. This choice is correct because tobacco smoke damages the air sacs in the lungs, leading to the development of emphysema. Prolonged exposure to cigarette smoke causes inflammation, reduces lung elasticity, and impairs gas exchange, which are hallmark features of emphysema’s pathophysiology and its primary cause worldwide.
B: Between 20 to 30 years of age does not represent a risk factor; age range alone does not cause emphysema. Emphysema typically develops later in life due to cumulative lung damage, not from a specific age bracket.
C: Asthma involves airway inflammation and constriction but does not primarily cause alveolar destruction characteristic of emphysema. While related to respiratory health, asthma and emphysema differ fundamentally in pathology and risk profiles.
D: Pollution contributes to lung disease but is less frequently identified as the main risk factor for emphysema. Its impact is generally secondary compared to the direct, extensive damage caused by tobacco smoke inhalation.
The nurse reviews morning lab results on his patients. Based on these lab results which patient should the nurse see first?
Rationale:
Potassium 6.4 mmol/K indicates the patient the nurse should see first. Elevated potassium, or hyperkalemia, can cause life-threatening cardiac arrhythmias, necessitating immediate assessment and intervention. Prompt recognition and treatment are critical to prevent cardiac arrest. This lab value represents an urgent electrolyte imbalance requiring prioritization over less immediately dangerous abnormalities like mild hyponatremia, anemia, or hyperglycemia.
A: Sodium 130 mEq/L reflects mild hyponatremia, which typically develops gradually and is less acutely life-threatening, allowing for lower priority compared to severe hyperkalemia.
C: Hgb 8.6 g/dL shows anemia, which is concerning but usually not emergent unless accompanied by symptoms like active bleeding or hemodynamic instability.
D: Fasting Glucose 145 mg/dL indicates hyperglycemia that requires management but is not immediately critical or as dangerous as elevated potassium affecting cardiac function.
A client is planning to perform nasotracheal suction for a client who has COPD and an artificial airway. Which of the following actions should the nurse take?
Rationale:
Preoxygenate the client with 100% oxygen for up to 3 min.
Preoxygenation with 100% oxygen before suctioning prevents hypoxia by increasing oxygen reserves, especially important for clients with COPD and artificial airways who are at risk of oxygen desaturation during suctioning procedures. This action helps maintain adequate oxygenation and reduces complications related to suctioning-induced hypoxemia.
B: Perform suctioning for no longer than 30 seconds. This time limit is important but secondary to preoxygenation, which directly prevents oxygen deprivation before suctioning begins.
C: Apply suction while inserting the catheter. Applying suction during insertion can cause mucosal damage and trauma, increasing patient discomfort and risk of bleeding.
D: Limit oxygen therapy to 50% prior to suctioning. Limiting oxygen to 50% contradicts the need for 100% oxygen preoxygenation to maximize oxygen reserves before suctioning.
The client is diagnosed with a transient ischemic attack (TIA). Which statement by the client indicates teaching about clopidogrel has been effective?
Rationale:
Clopidogrel will prevent clots from forming. Clopidogrel is an antiplatelet medication that reduces platelet aggregation, thereby preventing blood clots, which is essential in managing transient ischemic attacks and reducing stroke risk. This understanding reflects accurate client knowledge of the drug’s primary purpose in preventing clot-related complications.
A: My heart rate will no longer be irregular. This statement addresses cardiac rhythm issues, which clopidogrel does not directly influence, as it primarily focuses on clot prevention, not heart rate regulation.
B: This medication will help lower my blood pressure. Clopidogrel does not have antihypertensive properties; it specifically inhibits platelet aggregation, so it does not contribute to blood pressure control.
C: I will have decreased pain to my legs when I walk. Clopidogrel is not used to relieve claudication or leg pain; its role is in preventing thrombosis, not improving peripheral arterial circulation symptoms directly.
A nurse is assessing a client who has left-sided heart failure. Which of the following findings should the nurse expect?
Rationale:
Left-sided heart failure typically presents with a hacking cough. This occurs due to pulmonary congestion as the left ventricle fails to pump blood effectively, causing fluid buildup in the lungs and irritation of the respiratory tract, which triggers the cough reflex.
A: Abdominal distension relates to right-sided heart failure, where systemic venous congestion causes liver enlargement and ascites, not left-sided heart failure.
B: Jugular venous distention reflects increased central venous pressure seen primarily in right-sided heart failure, not the pulmonary symptoms of left-sided failure.
C: Dependent edema is characteristic of right-sided heart failure due to venous congestion and fluid retention, unlike left-sided failure which mainly affects the lungs.
A nurse is assigned care of a client who has HIV. Which of the following infection control precautions should the nurse plan to use while caring for this client?
Rationale:
Standard precautions should be used while caring for a client who has HIV. These precautions are designed to prevent transmission of bloodborne pathogens and other infectious agents through contact with blood, body fluids, and non-intact skin. HIV is primarily transmitted via blood and sexual contact, not through airborne, droplet, or contact routes, making standard precautions adequate.
A: Droplet precautions apply to infections spread by large respiratory droplets, such as influenza or pertussis, which are not typical transmission routes for HIV. Therefore, this method is unnecessary for HIV care.
B: Airborne precautions are used for diseases transmitted via tiny airborne particles, like tuberculosis or measles. HIV does not spread through airborne particles, so this precaution is irrelevant.
D: Contact precautions are intended for infections spread by direct or indirect contact with the patient or environment, such as MRSA. HIV's transmission routes do not require these additional measures beyond standard precautions.
A client with acute kidney injury (AKI) has a serum potassium level of 6.5 mEq/L. The nurse recognizes that administering IV calcium gluconate to this client will result in which of the following effects?
Rationale:
Administering IV calcium gluconate protects the heart from dysrhythmias while serum potassium is elevated. This medication stabilizes the cardiac cell membrane, reducing excitability and preventing dangerous arrhythmias caused by hyperkalemia without altering potassium levels. It serves as an immediate cardiac protective measure in acute hyperkalemia but does not remove or shift potassium from the body or cells.
A: Potassium will be removed from the body and excreted in the stool. This option misattributes a potassium-lowering effect to calcium gluconate, which does not facilitate potassium elimination via the gastrointestinal tract.
C: Potassium will temporarily shift from the blood into the cells. Calcium gluconate does not cause intracellular potassium shifts; this effect is characteristic of insulin or beta-agonists, not calcium administration.
D: Serum potassium levels will increase further due to this medication being administered. Calcium gluconate does not raise potassium levels; its role is cardiac membrane stabilization without affecting potassium concentration.
A nurse is assessing a client and discovers the infusion pump with the client's total parenteral nutrition (TPN) solution is not infusing. The nurse should monitor the client for which of the following clinical manifestations?
Rationale:
The nurse should monitor the client for shakiness and diaphoresis. This is because interruption of TPN can lead to hypoglycemia due to sudden cessation of glucose infusion, causing symptoms like tremors and sweating as the body reacts to low blood sugar levels. Prompt recognition is essential to prevent complications.
A: Fever and chills typically indicate infection, not a direct result of TPN infusion interruption. These signs relate more to septic complications rather than hypoglycemic reactions from halted glucose delivery.
B: Hypertension and crackles suggest fluid overload or cardiac issues, which are not immediate concerns during TPN pump failure. These symptoms reflect different pathophysiology unrelated to sudden glucose deprivation.
C: Excessive thirst and urination are classic signs of hyperglycemia or diabetes mellitus, not hypoglycemia caused by TPN interruption. These manifestations do not align with abrupt infusion cessation effects.
A staff nurse is teaching a client who has Addison's disease about the disease process. The client asks the nurse what causes Addison's disease. Which of the following responses should the nurse make?
Rationale:
Addison's disease is caused by the lack of production of aldosterone by the adrenal gland. This hormone deficiency leads to electrolyte imbalances, low blood pressure, and fatigue. The adrenal glands fail to produce sufficient aldosterone and cortisol, disrupting the body's ability to maintain salt and water balance, which is central to the disease's pathology and symptoms.
A: It is caused by the lack of production of insulin by the pancreas relates to diabetes mellitus, not Addison's disease, which involves adrenal hormone deficiency.
B: It is caused by the overproduction of growth hormone by the pituitary gland describes acromegaly or gigantism, unrelated to adrenal insufficiency.
C: It is caused by the overproduction of parathormone by the parathyroid gland pertains to hyperparathyroidism, affecting calcium levels, not adrenal hormone production.
A nurse is caring for a child who has enuresis. Which of the following is a complication of enuresis?
Rationale:
Emotional problems are a complication of enuresis. Enuresis often leads to feelings of embarrassment, low self-esteem, and social anxiety in children, affecting their emotional well-being. These psychological effects can interfere with normal development and social interactions, making emotional problems a significant concern in managing enuresis, beyond its physical symptoms or medical complications.
B: Urinary tract infections are not a typical consequence of enuresis, as bedwetting itself does not cause infections unless there is an underlying condition. The primary issue lies in emotional and psychological distress.
C: Urosepsis is a severe systemic infection originating from the urinary tract, which is unrelated to uncomplicated enuresis. Enuresis does not inherently cause such life-threatening infections.
D: Progressive kidney disease involves gradual loss of kidney function, which enuresis does not provoke. The condition primarily affects bladder control, not renal health or function.
A nurse is assessing a client who has fluid overload. Which of the following findings should the nurse expect? (Select all that apply.)
Rationale:
In fluid overload, the nurse should expect increased respiratory rate, increased blood pressure, and increased heart rate.
Increased respiratory rate occurs as the body attempts to compensate for pulmonary congestion. Elevated blood pressure results from expanded intravascular volume increasing cardiac workload. Increased heart rate arises due to sympathetic nervous system activation to maintain adequate tissue perfusion despite volume excess and potential cardiac strain.
A: Increased hematocrit reflects dehydration, not fluid overload, as excess fluid dilutes blood components lowering hematocrit levels.
D: Increased temperature is unrelated to fluid overload and typically indicates infection or inflammation, not volume status changes.
An RN is reviewing diagnostic tests for different types of anemia with a student nurse. Which of the following does the student correctly state is used for the diagnosis of types of anemia? (Select all that apply).
Rationale:
The student correctly identifies the Schilling Test, Hemoglobin electrophoresis, and Ferritin and Total Iron-Binding Capacity as diagnostic tools for types of anemia.
The Schilling Test assesses vitamin B12 absorption, Hemoglobin electrophoresis detects abnormal hemoglobin variants, and Ferritin with Total Iron-Binding Capacity evaluates iron status, all essential for differentiating anemia causes. These tests collectively provide a comprehensive approach to anemia diagnosis by targeting distinct pathophysiological mechanisms.
A: Enzyme-linked Immunosorbent assay (ELISA) primarily detects antibodies or antigens, not anemia types, making it unsuitable for anemia diagnosis.
D: Western Blot identifies specific proteins, often for infections or autoimmune diseases, and is unrelated to anemia evaluation or classification.
A nurse is teaching a client who has left-sided weakness how to use a quad cane. Which of the following client actions indicates an understanding of the teaching?
Rationale:
The client advances the weaker (left) leg forward to the cane.
This action demonstrates proper use of a quad cane by providing maximum support to the weaker side. Advancing the weaker leg toward the cane helps maintain balance and stability during ambulation, preventing falls and promoting safe, effective mobility. It aligns with recommended guidelines for cane usage in clients with unilateral weakness.
A: The client moves the cane 2 feet ahead. Moving the cane excessively far can destabilize the client and reduce support, as proper cane placement should be about 6 to 10 inches ahead to maintain balance efficiently.
B: The client holds the cane with their right hand. Holding the cane on the stronger side is advised; the client’s weaker left side requires the cane for support, so holding it in the right hand diminishes stability.
C: The client takes a step with their left foot first. Initiating a step with the weaker leg before the cane is unsupported and unsafe; the cane should advance first to provide a stable base for the weaker leg.
A nurse is providing teaching for a client who has a new diagnosis of gastroesophageal reflux disease (GERD). The client asks about foods he should avoid eating. Which of the following foods should the nurse tell him to avoid?
Rationale:
Chocolate should be avoided because it relaxes the lower esophageal sphincter, allowing stomach acid to reflux into the esophagus, which worsens GERD symptoms. This relaxation increases acid exposure and discomfort. Other foods listed do not have this effect, making chocolate a significant trigger that exacerbates acid reflux and should be limited in the diet of someone with GERD.
A: Nonfat milk does not aggravate GERD symptoms as it lacks fat content that can relax the lower esophageal sphincter, making it a safer choice for individuals managing reflux.
B: Apples are generally low in acid and fiber-rich, which can actually soothe the digestive tract rather than trigger reflux episodes in GERD patients.
C: Oatmeal is a whole-grain food that absorbs stomach acid and reduces symptoms, promoting digestive health without contributing to acid reflux or esophageal irritation.
A client with multiple sclerosis is seen by the home health nurse and complains of severe fatigue. Which of the following is the most appropriate nursing intervention?
Rationale:
Scheduling periods of rest in between activities is the most appropriate nursing intervention for a client with multiple sclerosis experiencing severe fatigue. This approach helps manage energy levels effectively. Fatigue in multiple sclerosis results from nerve damage and muscle weakness, so balancing activity with rest prevents exacerbation, promotes recovery, and optimizes daily functioning without overtaxing the client’s limited endurance.
A: Encourage deep-breathing exercises focuses on respiratory function but does not directly address fatigue management or energy conservation, which are essential in multiple sclerosis care.
B: Provide a relaxing warm bath may offer comfort but risks increasing fatigue through heat sensitivity common in multiple sclerosis patients, potentially worsening symptoms rather than alleviating them.
D: Administer multivitamins lacks direct evidence in reducing fatigue in multiple sclerosis and does not target the critical need for rest and energy conservation necessary for symptom control.
A nurse is performing an ECG on a client who is experiencing chest pain. Which of the following statements should the nurse make?
Rationale:
The nurse should say, "I will need to apply electrodes to your chest and extremities." This statement accurately informs the client about the placement of electrodes necessary for obtaining a comprehensive ECG tracing, which records electrical activity from multiple sites to assess heart function effectively during chest pain evaluation.
B: You may feel some discomfort during the procedure incorrectly suggests discomfort, but ECG electrode placement is typically painless and noninvasive, involving only adhesive patches on the skin, not causing pain.
C: The procedure will take about an hour inaccurately overestimates ECG duration, which usually lasts only a few minutes, making this statement misleading regarding time expectations.
D: We need to monitor your heart rate continuously after the procedure wrongly implies post-test continuous monitoring, whereas ECG primarily monitors during the test itself, not routinely afterward unless otherwise indicated.
A nurse is caring for a client who has heart failure and respiratory arrest. What should be the nurse's first action?
Rationale:
The nurse’s first action should be to establish an open airway. Ensuring airway patency is the priority in respiratory arrest because without an open airway, oxygen cannot reach the lungs or bloodstream. This action is critical to prevent hypoxia and allows for effective ventilation and oxygenation before other interventions like pulse assessment or IV access.
A: Auscultate for breath sounds delays immediate airway management, which is essential to restore oxygen flow first. Listening does not address the urgent need to open the airway in respiratory arrest.
C: Establishing IV access is important but secondary to securing an airway. Without airway patency, intravenous interventions will not improve oxygenation or breathing immediately.
D: Feeling for a carotid pulse helps assess circulation but does not address the critical need for airway clearance and ventilation in respiratory arrest.
A nurse is teaching a client who has tuberculosis and is to start combination drug therapy. Which of the following medications should the nurse plan to administer?
Rationale:
Rifampin, Isoniazid, and Pyrazinamide are all essential medications used in combination drug therapy to treat tuberculosis effectively. They work synergistically to eliminate Mycobacterium tuberculosis, prevent drug resistance, and shorten treatment duration. Each has a unique mechanism of action targeting different bacterial processes, which enhances therapeutic success and reduces the risk of relapse or treatment failure.
B: Acyclovir treats viral infections, particularly herpes viruses, and has no activity against Mycobacterium tuberculosis, making it irrelevant for tuberculosis management.
C: Montelukast is used to manage asthma and allergic rhinitis by blocking leukotrienes, without any antibacterial properties against tuberculosis pathogens.
A client receives a prescription for allopurinol. Which information provided by the client requires additional instruction by the nurse?
Rationale:
Doubling the dose if a dose is missed requires additional instruction by the nurse. Allopurinol dosing should not be doubled as it can increase the risk of toxicity and adverse effects. Proper adherence involves taking the missed dose as soon as remembered or skipping it if close to the next dose, avoiding overdose and ensuring safe therapeutic levels.
A: Avoid taking on an empty stomach is appropriate as allopurinol can cause gastrointestinal upset; taking with food helps reduce irritation and improves tolerance, so no extra instruction is needed.
B: Consume 2 liters of water daily supports kidney function and prevents uric acid crystallization, which is essential in managing gout and medication safety, making this advice correct and requiring no correction.
C: Reduce caffeine and acidic intake helps minimize uric acid buildup and gout flare-ups; this dietary advice complements allopurinol therapy and does not warrant additional nurse instruction.
A nurse is teaching a client who has a fractured femur about fat emboli syndrome. Which of the following findings should the nurse include as a manifestation of a fat embolism?
Rationale:
Petechiae on the chest is a key manifestation of fat embolism syndrome. This occurs due to embolized fat globules causing capillary damage and small blood vessel occlusion, leading to characteristic pinpoint hemorrhages. Recognizing petechiae helps differentiate fat embolism from other complications after fractures, guiding timely intervention and improving patient outcomes through appropriate monitoring and treatment strategies.
A: Paresthesia distal to the fracture involves nerve irritation or damage but does not specifically indicate fat embolism, which primarily affects the pulmonary and integumentary systems rather than localized sensory nerves.
B: Fever may occur in many conditions, including infections, but it is not a primary or distinctive sign of fat embolism syndrome, which is characterized more by respiratory and skin changes.
C: Swollen calf suggests deep vein thrombosis rather than fat embolism; fat emboli typically cause systemic symptoms like respiratory distress and petechiae, not localized limb swelling.
A nurse is teaching the partner of a client who had an acute myocardial infarction (MI) about the reason blood was drawn from the client. Which of the following statements should the nurse make regarding cardiac enzyme studies?
Rationale:
Cardiac enzyme studies help determine the degree of damage to the heart tissues. These enzymes, released when heart muscle cells are injured during an MI, provide critical information about the extent of myocardial injury, guiding treatment decisions. Elevated enzyme levels confirm tissue damage severity, assisting healthcare providers in assessing the client’s condition and monitoring recovery progress following the infarction.
A: These tests evaluate heart structure and valve mobility through imaging, not enzyme levels, so this choice misrepresents the purpose of cardiac enzyme studies in MI assessment.
B: Cardiac enzymes indicate tissue damage but do not pinpoint the MI’s exact anatomical location within the heart muscle.
C: Pulmonary congestion diagnosis relies on clinical signs and imaging, not enzyme levels, which specifically reflect myocardial cell injury rather than fluid accumulation in the lungs.
The nurse is caring for a client who is in the later stages of left-sided heart failure. Which chief complaint would the nurse expect the client to report?
Rationale:
The nurse would expect the client to report marked limitation with physical activity but comfortable at rest. This symptom reflects the progressive nature of left-sided heart failure, where decreased cardiac output leads to fatigue and dyspnea during exertion, yet patients often remain symptom-free or comfortable while at rest, indicating advancing disease severity without constant distress.
B: Angioedema and urticaria relate to allergic reactions or medication side effects, not typical manifestations of left-sided heart failure, which primarily involves cardiac and respiratory symptoms rather than dermatologic conditions.
C: Increased urine output contradicts the expected oliguria in heart failure due to poor renal perfusion and fluid retention, making this an unlikely symptom in advanced left-sided heart failure.
D: Chest pain during sleep relieved with nitroglycerin characterizes angina pectoris, which differs from heart failure symptoms that focus more on dyspnea and fatigue rather than episodic ischemic pain.
A nurse is caring for a client who has returned from the surgical suite following surgery for a fractured mandible. The client had intermaxillary fixation to repair and stabilize the fracture. Which of the following actions is the priority for the nurse to take?
Rationale:
Prevent aspiration is the priority action for the nurse caring for a client with intermaxillary fixation following mandible surgery. This fixation restricts mouth opening, increasing the risk of airway obstruction and aspiration. Immediate airway protection and monitoring for respiratory distress are crucial to prevent life-threatening complications, making aspiration prevention the foremost concern during postoperative care in this scenario.
A: Relieve the client's pain Pain management is important but secondary to ensuring airway safety, as pain does not pose an immediate threat to breathing or survival in this context.
B: Promote oral hygiene Oral hygiene supports healing and prevents infection but does not address the urgent risk of compromised airway or aspiration after surgery with fixation.
C: Ensure adequate nutrition Nutrition is necessary for recovery but can be managed once airway protection is secured, since feeding difficulties are expected with jaw immobilization.
A patient who has gastroesophageal reflux disease (GERD) is experiencing increasing discomfort. Which patient statement to the nurse indicates that additional teaching about GERD is needed?
Rationale:
The statement "I eat small meals and have a bedtime snack" indicates that additional teaching about GERD is needed. Small meals are appropriate, but eating a bedtime snack can exacerbate reflux symptoms by increasing stomach acid production and delaying gastric emptying, which worsens discomfort during sleep.
A: I quit smoking years ago, but I chew gum. Chewing gum stimulates saliva production, which can neutralize acid and reduce reflux episodes, making this an acceptable practice for managing GERD symptoms.
B: I sleep with the head of the bed elevated on 4-inch blocks. Elevating the head of the bed helps prevent acid from flowing back into the esophagus during sleep, reducing nighttime symptoms and is a recommended management strategy.
C: I take antacids between meals and at bedtime each night. Antacids neutralize stomach acid and provide symptom relief, especially when taken between meals and before bedtime, aligning with typical GERD treatment guidelines.
The nurse is caring for a client diagnosed with disseminated intravascular coagulation (DIC). When completing an assessment for decreased perfusion from clotting, the nurse would observe for which manifestation?
Rationale:
Decreased perfusion from clotting in DIC is evidenced by cyanosis. Cyanosis indicates impaired oxygen delivery due to microvascular thrombi blocking blood flow, causing tissue hypoxia. This manifestation directly reflects reduced perfusion, which is critical in assessing the severity of clotting complications in DIC, highlighting the nurse’s focus on vascular obstruction and resultant oxygen deprivation.
B: Petechiae represent small hemorrhagic spots due to platelet consumption and bleeding, not decreased perfusion from clotting. They indicate bleeding tendencies rather than tissue hypoxia or vascular obstruction associated with thrombi.
C: Epistaxis is bleeding from the nose reflecting coagulopathy and platelet dysfunction in DIC. It signifies hemorrhagic complications rather than signs of impaired blood flow or tissue oxygenation.
D: Hematuria involves blood in urine, showing bleeding within the urinary tract from clotting factor depletion. It does not specifically indicate decreased perfusion or oxygen delivery caused by microvascular thrombosis.
Patient Summary
Presenting Complaint:
Time of Arrival: 0900 hours
Symptoms: Client reports not feeling well for the past 12 hours, with increasing blood glucose levels. Client has a history of type 1 diabetes mellitus and hypertension. Recent treatment for bronchitis and pneumonia. Reports nausea, decreased appetite, frequent urination, and extreme thirst.

Provider's Prescriptions
Fluids: Administer 0.9% sodium chloride at 15 ml/kg/hr for 1 hr, then reduce to 10 ml/kg/hr.
Potassium: Potassium chloride 20 mEq/L IV PRN if potassium is less than 5.0 mEq/L.
Insulin: Regular insulin continuous infusion, titrate per DKA protocol once potassium is greater than 3.3 mEq/L.
Anti-nausea: Ondansetron 4 mg IV bolus every 4 hr PRN for nausea.
Pain Relief: Acetaminophen 650 mg every 4 hr PRN for pain.
Magnesium: Magnesium sulfate 2 g IV over 2 hr for hypomagnesemia.
Monitoring: Strict intake and output, blood glucose level hourly.
The nurse should plan to first administer….. followed by……
Rationale:
The nurse should plan to first administer 0.9% sodium chloride followed by insulin.
Administering 0.9% sodium chloride first is crucial to address dehydration and stabilize hemodynamics in diabetic ketoacidosis (DKA). Insulin administration follows once potassium is above 3.3 mEq/L to prevent hypokalemia. This sequential approach ensures safe correction of metabolic abnormalities and prevents complications related to potassium shifts during insulin therapy.
A: Magnesium supplementation does not address immediate DKA management priorities and is only indicated if hypomagnesemia is confirmed.
B: Acetaminophen targets pain relief but does not correct critical metabolic disturbances like hyperglycemia or dehydration in DKA.
C: Potassium is only given if levels drop below 5.0 mEq/L; current potassium is elevated, making supplementation premature and potentially harmful.
F: Ondansetron manages nausea but does not treat life-threatening dehydration or hyperglycemia, which require urgent fluid and insulin therapy.
A 24-year-old female client comes to the ambulatory care center in moderate distress with a probable diagnosis of acute cystitis. Which symptom should the nurse expect the client to report during the assessment?
Rationale:
Dysuria is the symptom the nurse should expect, as it refers to painful or difficult urination, which is a hallmark complaint in acute cystitis. This urinary tract infection primarily affects the bladder, causing inflammation that leads to burning sensations during urination, increased frequency, and urgency, making dysuria the most relevant and common symptom reported by affected clients in clinical settings.
A: Nasal congestion relates to upper respiratory issues, not urinary tract infections, and does not correspond with cystitis symptoms.
C: Shortness of breath involves respiratory or cardiac conditions, unrelated to bladder inflammation or urinary discomfort in cystitis cases.
D: Joint pain usually indicates musculoskeletal or systemic inflammatory disorders, which are not typical manifestations of acute bladder infections like cystitis.
A nurse is caring for a postoperative client experiencing shallow respirations and refusing to cough or get out of bed to the chair. The nurse should educate the client about the increased risk of which complication?
Rationale:
Shallow respirations and refusal to cough or mobilize increase the risk of atelectasis.
Atelectasis occurs when alveoli collapse due to inadequate lung expansion, often from shallow breathing and immobility after surgery. Coughing and deep breathing help re-expand alveoli and clear secretions, preventing lung collapse and hypoxia. Educating the client on these actions reduces atelectasis risk and promotes pulmonary recovery postoperatively.
A: Skin breakdown Risk arises mainly from immobility and pressure, not directly linked to shallow respirations or refusal to cough.
B: Pneumonia Although pneumonia can result from poor lung hygiene, the immediate risk from shallow breathing is alveolar collapse, not infection.
C: Thrombosis While immobility contributes to thrombosis, shallow breathing and refusal to cough primarily affect lung function rather than clot formation.
A nurse is caring for a client who has an endotracheal tube and is receiving mechanical ventilation. Which of the following actions should the nurse take to reduce the risk of ventilator-associated pneumonia?
Rationale:
Maintaining oral hygiene by brushing the client's teeth with a suction toothbrush every 12 hours helps reduce the risk of ventilator-associated pneumonia. This practice decreases oral bacterial colonization, limiting the aspiration of pathogens into the lower respiratory tract. Effective oral care is a critical preventative measure, as it directly targets one of the primary sources of infection in mechanically ventilated patients.
A: Position the head of the client's bed in the flat position increases aspiration risk, which can promote pneumonia development. Elevating the head is preferred to reduce ventilator-associated pneumonia incidence.
B: Providing humidity by maintaining moisture within the ventilator tubing supports mucociliary function but does not directly prevent bacterial colonization or aspiration, which are central to pneumonia prevention.
C: Turning the client every 4 hours aids in secretion clearance but less effectively prevents pneumonia compared to more frequent repositioning and oral hygiene practices that target bacterial reduction.
A nurse is caring for a client who is receiving a 0.9% sodium chloride via IV infusion. The client has become dyspneic with a blood pressure of 140/100 mm Hg, a fluid intake of 960 mL, and an output of 300 mL in the past 12 hr. Which of the following actions should the nurse take?
Rationale:
Slowing the infusion rate and contacting the provider is the appropriate action. The client shows signs of fluid overload, such as dyspnea and elevated blood pressure, combined with a high intake and low output, indicating the need to reduce fluid administration and seek further medical guidance to prevent complications like pulmonary edema or worsening hypertension.
A: Lower the head of the bed to semi-Fowler's decreases respiratory effort and oxygenation, which contradicts the need to ease dyspnea by promoting better lung expansion and reducing fluid overload effects.
B: Administer prescribed corticosteroids does not address fluid overload or hypertension directly and is unrelated to the acute management of IV fluid complications in this scenario.
D: Change infusion to lactated Ringer's and maintain rate risks exacerbating fluid overload since the client already has signs of excess fluid and needs reduced fluid volume rather than substitution.
A nurse is planning care for a client who is receiving heparin IV to treat a pulmonary embolism. Which of the following medications should the nurse plan to have available?
Rationale:
Protamine sulfate should be available because it is the antidote used to reverse the effects of heparin in case of overdose or bleeding complications.
Protamine sulfate neutralizes heparin by forming a stable complex, quickly reversing anticoagulation. This rapid action is critical during emergencies such as excessive bleeding, ensuring patient safety while managing pulmonary embolism treatment with heparin therapy.
B: Vitamin K reverses warfarin, not heparin. It is ineffective against heparin-induced anticoagulation and therefore irrelevant for managing heparin overdose or bleeding.
C: Flumazenil is a benzodiazepine antagonist used to reverse sedation, unrelated to anticoagulant therapy or pulmonary embolism treatment.
D: Acetylcysteine treats acetaminophen toxicity by replenishing glutathione; it has no role in reversing heparin’s anticoagulant effects.
A nurse is reviewing strategies to address health disparities in a community setting in alignment with Healthy People 2030 objectives. Which of the following actions by the nurse best demonstrates the application of Healthy People 2030 goals to reduce health disparities?
Rationale:
Developing and implementing a culturally competent health education program tailored to underserved populations to improve access to preventive services best demonstrates the application of Healthy People 2030 goals to reduce health disparities. This approach specifically targets underserved groups, enhancing equitable access to preventive care, and aligns with Healthy People 2030’s emphasis on culturally appropriate interventions to eliminate health disparities and promote health equity across diverse populations.
B: Prioritizing high-cost interventions for clients with advanced diseases neglects preventive care, which Healthy People 2030 emphasizes to reduce disparities by addressing health before conditions worsen, limiting its effectiveness in reducing disparities.
C: Focusing solely on individual care without considering social determinants overlooks crucial factors influencing health disparities, contradicting Healthy People 2030’s holistic strategy to address broader community health influences.
D: Providing standard health education materials ignores cultural, linguistic, and socioeconomic differences, reducing relevance and effectiveness in diverse populations, which Healthy People 2030 aims to address through tailored interventions.
A nurse is admitting a client who has meningitis. Which of the following findings should the nurse expect?
Rationale:
Photophobia is a common symptom of meningitis caused by meningeal irritation leading to light sensitivity. This symptom often accompanies other signs like headache and neck stiffness, indicating inflammation of the meninges, which is characteristic of meningitis.
A: Petechiae on the chest typically suggest meningococcal septicemia and not all meningitis cases, so they are not a definitive expected finding for meningitis alone.
B: Bradycardia is not typical in meningitis; tachycardia is more common due to fever and systemic infection response.
C: Intermittent headache is less characteristic since meningitis headaches are usually severe and persistent, reflecting continuous meningeal inflammation.
A nurse is monitoring a client who has a traumatic brain injury. Which of the following findings should the nurse identify as a manifestation of Cushings triad?
Rationale:
An increase in blood pressure from 130/80 mm Hg to 180/100 mm Hg is a manifestation of Cushing’s triad. This triad includes hypertension with a widening pulse pressure, bradycardia, and irregular respirations, indicating increased intracranial pressure. The significant rise in blood pressure reflects the body’s attempt to maintain cerebral perfusion despite brain injury.
B: Decrease in heart rate to 120 bpm contradicts Cushing’s triad, which involves bradycardia, or a slow heart rate, rather than tachycardia. A heart rate of 120 bpm represents an elevated pulse, not a slowing one.
C: Rapid shallow respirations do not align with the irregular or decreased respiratory pattern seen in Cushing’s triad. The triad typically presents with abnormal, sometimes slowed breathing, not increased respiratory rate.
D: Hypotension opposes the hypertension characteristic of Cushing’s triad. This triad is marked by elevated blood pressure as a compensatory mechanism, so low blood pressure does not fit this diagnostic pattern.
A client has a prescription for heparin 5000 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 action ensures the correct medication form is obtained, as low molecular weight heparin differs pharmacologically and administratively from unfractionated heparin, preventing dosing errors and maintaining patient safety by adhering strictly to the prescribed medication and route.
A: Requesting a prescription change assumes the medication and route are interchangeable, which they are not, risking improper treatment and potential harm due to differing drug properties and administration protocols.
B: Calculating an equivalent dose risks inaccurate dosing because low molecular weight heparin's potency and pharmacokinetics differ significantly from unfractionated heparin, making direct substitution unsafe.
C: Diluting the available heparin in saline is inappropriate since low molecular weight heparin comes in pre-filled syringes designed for specific routes; dilution could alter effectiveness and safety.
A nurse is caring for a client diagnosed with a pulmonary embolism that is placed on a continuous heparin infusion. The nurse should notify the health care provider for which of the following findings?
Rationale:
The nurse should notify the health care provider if the client's partial thromboplastin time (PTT) is 70 seconds and the control is 25-40 seconds.
This elevated PTT indicates excessive anticoagulation from the heparin infusion, increasing the risk of bleeding complications. Immediate provider notification is essential to adjust dosages and prevent hemorrhagic events. Monitoring PTT ensures therapeutic effectiveness without dangerous over-anticoagulation.
A: Client develops petechiae on the arms, legs, and abdomen. This suggests possible bleeding or platelet issues but is less urgent than dangerously prolonged PTT levels requiring immediate action.
B: Health care provider orders Coumadin 2.5 mg P.O. to begin today. Initiating Coumadin is a standard protocol alongside heparin; it does not require urgent notification.
C: Client develops slight ecchymosis at the venipuncture site. Minor bruising at the site is common and expected with heparin therapy, not necessitating immediate provider notification.
A nurse is preparing to administer ampicillin 500 mg via intermittent IV bolus over 30 min. Available is 500 mg ampicillin in 50 mL dextrose 5% in water (DSW). The nurse should set the pump to deliver how many mL/hr?
Rationale:
The nurse should set the pump to deliver 100 mL/hr.
This rate is calculated by dividing the total volume (50 mL) by the infusion time (0.5 hours), resulting in 100 mL/hr. Administering the medication over 30 minutes ensures proper dosing speed, preventing complications linked to too rapid or too slow infusion, maintaining therapeutic effectiveness and patient safety during the IV bolus.
A: 50 mL/hr Infusing at 50 mL/hr would deliver the dose over one hour, not the required 30 minutes, prolonging administration and potentially delaying therapeutic effects.
B: 250 mL/hr Delivering 250 mL/hr would infuse the volume too quickly, increasing risk of adverse reactions and exceeding the prescribed 30-minute administration time significantly.
C: 75 mL/hr Setting the pump to 75 mL/hr results in an infusion time of 40 minutes, which is longer than the specified 30-minute duration, reducing dosing accuracy.
The nurse is caring for a patient with obesity who is being considered for bariatric surgery. Which do the criteria guidelines for bariatric surgery include?
Rationale:
A body mass index (BMI) of 40 kg/m² or more is included in the criteria guidelines for bariatric surgery. This threshold identifies patients with severe obesity who are most likely to benefit from surgical intervention due to the associated high risk of comorbid conditions and limited success with non-surgical weight loss methods, making surgery a viable, effective treatment option.
A: BMI of 28 kg/m² or more reflects overweight status but does not meet the established bariatric surgery criteria, which require higher BMI thresholds to justify surgical risks and benefits.
B: BMI of 32 kg/m² or more with co-morbidities is below the typical cutoff; guidelines generally require a BMI of 35 or higher with comorbidities, not 32, for surgical consideration.
C: BMI of 30 kg/m² or more defines obesity but is insufficient alone for surgery; bariatric guidelines recommend higher BMI or additional health complications to qualify.
A nurse is collecting data from a client who has pulmonary tuberculosis. Which of the following findings should the nurse expect?
Rationale:
Fatigue is an expected finding in clients with pulmonary tuberculosis due to the chronic infection causing systemic weakness and decreased energy levels. This symptom reflects the body’s ongoing battle against the bacteria, leading to overall malaise and tiredness that persists despite rest. Fatigue often accompanies other constitutional symptoms of tuberculosis, such as weight loss and night sweats, signaling disease progression.
A: Increased appetite contradicts typical tuberculosis symptoms, which usually include weight loss and decreased appetite, reflecting catabolic state and systemic illness impact rather than enhanced hunger or food intake.
B: Edema does not typically present in pulmonary tuberculosis; it is more associated with fluid retention disorders, cardiovascular or renal issues, not the chronic infectious process characteristic of tuberculosis.
C: High fever in the early morning is uncommon because tuberculosis fevers usually occur in the afternoon or evening and present as low-grade rather than high-grade fevers, differentiating it from other infections.
