Nursing Elites

1. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

2. A client with a history of asthma reports using an albuterol inhaler more frequently than prescribed. Which action should the nurse take first?

• A. Notify the healthcare provider immediately
• B. Schedule a pulmonary function test
• C. Assess the client's respiratory status
• D. Instruct the client to decrease inhaler use

Correct answer: C

Rationale: Increased use of a rescue inhaler like albuterol may indicate worsening asthma symptoms. The nurse should first assess the client's respiratory status to determine the severity of the issue and the next steps in care. Option A is not the first action because assessing the client's condition should precede notifying the healthcare provider. Option B, scheduling a pulmonary function test, is not the priority as immediate assessment of the client's respiratory status is crucial. Instructing the client to decrease inhaler use should come after assessing the client's condition to ensure the appropriate intervention.

3. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

4. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess for allergies to topical cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.

5. A client with pheochromocytoma is admitted to the hospital. Which intervention has the highest priority?

• A. Monitor blood pressure frequently
• B. Start intravenous fluids at a fast rate
• C. Administer pain medication to reduce discomfort
• D. Give antihypertensive medications as prescribed

Correct answer: B

Rationale: The correct answer is B: Start intravenous fluids at a fast rate. In a client with pheochromocytoma, the highest priority intervention is to ensure adequate intravascular volume before initiating any other treatment. This helps prevent a sudden drop in blood pressure that can occur due to the release of catecholamines during tumor manipulation. While monitoring blood pressure frequently is essential, ensuring adequate intravascular volume takes precedence. Administering pain medication and antihypertensive medications are important but are not the highest priority in the initial management of pheochromocytoma.
