Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

2. A scrub nurse preparing for the first surgery of the day asks if a 3-minute surgical hand scrub is adequate. What should the circulating nurse advise?

• A. Proceed with surgery preparation
• B. Extend scrub time to 5 minutes
• C. Use an alcohol-based hand sanitizer
• D. Scrub time depends on the type of surgery

Correct answer: B

Rationale: The circulating nurse should advise the scrub nurse to extend the hand scrub to 5 minutes for thorough preparation, especially for the first surgery of the day. Choice A is incorrect as it does not address the need for a longer scrub time. Choice C is incorrect as alcohol-based hand sanitizer is not a substitute for a thorough surgical hand scrub. Choice D is incorrect as while scrub time may vary based on the surgery, for the first surgery of the day, a longer scrub time is recommended as a standard practice.

3. A client with tuberculosis is prescribed rifampin. What side effect should the nurse inform the client about?

• A. Report orange-colored urine as a sign of kidney dysfunction.
• B. Expect red-orange discoloration of urine as a harmless side effect.
• C. Monitor for signs of liver toxicity.
• D. Call the healthcare provider if vision changes occur.

Correct answer: B

Rationale: The correct answer is B. Rifampin can cause red-orange discoloration of bodily fluids, including urine, saliva, and tears. This is a harmless side effect, but clients should be informed beforehand to prevent alarm. Choice A is incorrect as orange-colored urine is not a sign of kidney dysfunction related to rifampin. Choice C is incorrect because rifampin is more commonly associated with liver toxicity rather than kidney dysfunction. Choice D is incorrect as vision changes are not a typical side effect of rifampin.

4. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

5. A client with cirrhosis is prescribed spironolactone to manage ascites. Which serum laboratory value is most important for the nurse to monitor?

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

Correct answer: D

Rationale: The correct answer is D: Potassium. Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Monitoring potassium levels is crucial to prevent complications like cardiac arrhythmias. Choices A, B, and C are incorrect because sodium, calcium, and magnesium levels are not directly affected by spironolactone use for managing ascites in cirrhosis.
