Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

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

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client with peripheral artery disease reports leg cramps while walking. What intervention should the nurse recommend?

• A. Encourage the client to rest immediately when cramping occurs.
• B. Recommend that the client increase their intake of potassium-rich foods.
• C. Advise the client to take a short break, then continue walking.
• D. Recommend that the client avoid walking altogether to prevent cramps.

Correct answer: C

Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.

3. An unlicensed assistive personnel (UAP) reports a weak pulse of 44 beats per minute in a client. What action should the charge nurse implement?

• A. Have the UAP recheck the pulse and report back.
• B. Have a licensed practical nurse (LPN) assess the client for apical-radial pulse deficit.
• C. Call the healthcare provider for further instructions.
• D. Immediately call the healthcare provider and prepare for transfer to critical care.

Correct answer: B

Rationale: The correct action is to have a licensed practical nurse (LPN) assess the client for an apical-radial pulse deficit. This assessment can provide further information about the client’s cardiovascular status and help determine if further intervention is necessary. Having the UAP recheck the pulse may delay appropriate assessment and intervention. Calling the healthcare provider for further instructions may not be necessary at this point unless the LPN assessment indicates a need for it. Immediately transferring the client to critical care without further assessment is not warranted based solely on the initial report of a weak pulse.

4. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?

• A. Losartan
• B. Spironolactone
• C. Metoprolol
• D. Furosemide

Correct answer: B

Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.

5. The nurse is providing care for a client with heart failure who is prescribed furosemide. Which laboratory value should the nurse monitor closely?

• A. Calcium level
• B. Sodium level
• C. Magnesium level
• D. Potassium level

Correct answer: D

Rationale: The correct answer is D: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. While calcium, sodium, and magnesium levels are important in various conditions and treatments, they are not the primary electrolyte affected by furosemide.
