Nursing Elites

1. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

2. A client with a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client’s urine output is 25 ml/hour. What is the most likely cause?

• A. This is a normal finding after surgery.
• B. Oliguria signals tubular necrosis related to hypoperfusion.
• C. Oliguria signals dehydration and fluid loss.
• D. Urine output of 25 ml/hour is an expected finding after splenectomy.

Correct answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

3. A client is diagnosed with chronic renal failure, and the nurse is teaching dietary modifications. What should be limited in this client's diet?

• A. Carbohydrates
• B. Fats
• C. Proteins
• D. Vitamins

Correct answer: C

Rationale: In chronic renal failure, proteins should be limited in the diet. When the kidneys are not functioning well, the buildup of protein byproducts can put additional stress on them. Limiting protein intake can help reduce the burden on the kidneys. Carbohydrates and fats do not need to be restricted in the same way as proteins. Vitamins are essential nutrients that should not be limited in the diet unless specified by a healthcare provider for a specific reason.

4. A client with acute kidney injury has an elevated creatinine level. What is the nurse's priority intervention?

• A. Administer diuretics as prescribed.
• B. Prepare the client for dialysis.
• C. Restrict the client’s fluid intake.
• D. Notify the healthcare provider immediately.

Correct answer: B

Rationale: The correct answer is B: Prepare the client for dialysis. Clients with acute kidney injury and elevated creatinine may require dialysis to support kidney function and remove waste products from the blood. Preparing for dialysis ensures timely intervention in preventing further complications. Administering diuretics (Choice A) may worsen the client's condition by further compromising kidney function. Restricting fluid intake (Choice C) may be necessary in some cases, but it is not the priority over preparing for dialysis. Notifying the healthcare provider (Choice D) is important, but the immediate priority is to prepare for dialysis to address the acute kidney injury and elevated creatinine level.

5. An older adult client with gastroenteritis has been taking the antidiarrheal diphenoxylate for the past 24 hours. What finding requires the nurse to take further action?

• A. Monitor the client’s fluid intake.
• B. Obtain a stool sample for testing.
• C. Administer a laxative to clear the infection.
• D. Assess skin turgor and provide fluids.

Correct answer: D

Rationale: The correct answer is D. Assessing skin turgor is crucial as tented skin turgor indicates dehydration, which can be worsened by antidiarrheal medications like diphenoxylate. Providing fluids is essential to address dehydration in this client. Monitoring fluid intake (choice A) is important, but assessing skin turgor takes precedence in this situation. Obtaining a stool sample for testing (choice B) could be necessary for diagnostic purposes but is not the immediate priority. Administering a laxative (choice C) is contraindicated in this case as it can worsen the client's condition by further exacerbating fluid loss.
