Nursing Elites

1. A nurse is caring for a client who is receiving furosemide. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Serum sodium.
• B. Serum glucose.
• C. Serum potassium.
• D. Serum calcium.

Correct answer: C

Rationale: The correct answer is C: Serum potassium. Furosemide is a potassium-wasting diuretic, meaning it can lead to potassium loss in the body. Monitoring serum potassium levels is crucial to evaluate the effectiveness of furosemide and prevent hypokalemia. Options A, B, and D are incorrect because furosemide does not directly affect sodium, glucose, or calcium levels in the same way it impacts potassium levels.

2. A nurse is caring for a client who has a chest tube. Which of the following actions should the nurse take?

• A. Clamp the chest tube for 15 minutes every 2 hours.
• B. Empty the drainage collection chamber when it is half full.
• C. Keep the drainage system below the level of the client's chest.
• D. Strip the chest tube every 2 hours to maintain patency.

Correct answer: C

Rationale: The correct action the nurse should take when caring for a client with a chest tube is to keep the drainage system below the level of the client's chest. This positioning helps prevent fluid from flowing back into the pleural space, ensuring proper drainage and effective functioning of the chest tube. Clamping the chest tube intermittently or stripping it frequently can lead to complications and should be avoided. Emptying the drainage collection chamber at specific intervals may vary based on institutional protocols, but it should be done when it is no more than two-thirds full to prevent backflow and maintain accurate monitoring of drainage output.

3. What is the priority intervention for a patient with suspected pulmonary embolism?

• A. Administer oxygen
• B. Administer anticoagulants
• C. Administer bronchodilators
• D. Reposition the patient

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a patient with suspected pulmonary embolism. Maintaining adequate oxygenation is crucial in these patients to prevent hypoxemia and support oxygen delivery to tissues. Administering anticoagulants may be necessary but is not the initial priority. Administering bronchodilators is not indicated for pulmonary embolism. Repositioning the patient does not address the immediate need for oxygenation.

4. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

5. A client has a new prescription for spironolactone. Which of the following instructions should the nurse include?

• A. Take this medication with a potassium supplement.
• B. Avoid foods that contain potassium.
• C. Limit your fluid intake while taking this medication.
• D. Take this medication on an empty stomach.

Correct answer: B

Rationale: The correct answer is B because spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium. Instructing the client to avoid foods high in potassium helps prevent hyperkalemia, a potential side effect of spironolactone. Choice A is incorrect because taking spironolactone with a potassium supplement can increase the risk of hyperkalemia. Choice C is not directly related to spironolactone use. Choice D is also incorrect as spironolactone does not need to be taken on an empty stomach.
