1. What is the primary purpose of administering anticoagulants to a patient with atrial fibrillation?

Correct answer: B

Rationale: The primary purpose of administering anticoagulants to a patient with atrial fibrillation is to prevent clot formation. Patients with atrial fibrillation are at an increased risk of forming blood clots in the heart, which can lead to stroke if they travel to the brain. Anticoagulants help to reduce this risk by inhibiting the clotting process. Therefore, choices A, C, and D are incorrect because anticoagulants do not primarily aim to reduce blood pressure, prevent arrhythmias, or reduce inflammation in patients with atrial fibrillation.

2. Which symptoms should the nurse expect a client to exhibit who is diagnosed with a pheochromocytoma?

Correct answer: B

Rationale: Correct. Pheochromocytoma is a catecholamine-secreting non-cancerous tumor of the adrenal medulla. The classic triad of symptoms includes headache, diaphoresis (excessive sweating), and palpitations, which result from the overproduction of catecholamines like epinephrine and norepinephrine. Numbness, tingling, and cramps in the extremities (Option A) are not characteristic of pheochromocytoma. Cyanosis, fever, and classic signs of shock (Option C) are not typical symptoms of this condition. Nausea, vomiting, and muscular weakness (Option D) are not commonly associated with pheochromocytoma.

3. The nurse is preparing to administer the first dose of intravenous ceftriaxone (Rocephin) to a patient. When reviewing the patient’s chart, the nurse notes that the patient previously experienced a rash when taking amoxicillin. What is the nurse’s next action?

Correct answer: A

Rationale: When a patient has a history of a rash with amoxicillin, a beta-lactam antibiotic like ceftriaxone should be administered cautiously due to a possible cross-reactivity. The nurse should still administer the drug but closely monitor the patient for any signs of hypersensitivity reactions. Asking for a different generation of cephalosporin or suggesting an oral form does not address the potential cross-reactivity issue. Contacting the provider to report drug hypersensitivity would delay care when the patient needs immediate treatment.

4. A client is recovering after a nephrostomy tube was placed 6 hours ago. The nurse notes drainage in the tube has decreased from 40 mL/hr to 12 mL over the last hour. Which action should the nurse take?

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to assess the client’s abdomen and vital signs. The nephrostomy tube should have a consistent amount of drainage, and a decrease may indicate obstruction. Before notifying the provider, the nurse must assess the client for pain, distention, and changes in vital signs. This assessment is crucial to gather essential information to report accurately. Documenting the finding without further assessment may delay necessary intervention. Evaluating the tube as working in the hand-off report or clamping the tube prematurely are not appropriate actions and could lead to complications if there is an obstruction.

5. During an assessment on a patient brought to the emergency department for treatment for dehydration, the nurse notes a respiratory rate of 26 breaths/minute, a heart rate of 110 beats/minute, a blood pressure of 86/50 mm Hg, and a temperature of 39.5° C. The patient becomes dizzy when transferred from the wheelchair to a bed. The nurse observes cool, clammy skin. Which diagnosis does the nurse suspect?

Correct answer: A

Rationale: The nurse should suspect Fluid Volume Deficit (FVD) in this patient. Signs of FVD include elevated temperature, tachycardia, tachypnea, hypotension, orthostatic hypotension, and cool, clammy skin, which align with the patient's assessment findings. Choices B, C, and D are incorrect. Fluid Volume Excess (FVE) typically presents with bounding pulses, elevated blood pressure, dyspnea, and crackles. Mild extracellular fluid (ECF) deficit usually manifests as thirst. Renal failure commonly results in Fluid Volume Excess (FVE) rather than Fluid Volume Deficit (FVD).
