Nursing Elites

1. A client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?

• A. Blood urea nitrogen (BUN)
• B. Serum potassium
• C. Serum calcium
• D. Creatinine clearance

Correct answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.

2. A 70-year-old man presents with weight loss, jaundice, and a palpable mass in the right upper quadrant. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Gallstones
• B. Hepatitis
• C. Pancreatic cancer
• D. Primary biliary cirrhosis

Correct answer: C

Rationale: The presentation of a 70-year-old man with weight loss, jaundice, a palpable mass in the right upper quadrant, and elevated bilirubin and alkaline phosphatase levels is highly suggestive of pancreatic cancer. This clinical scenario, known as Courvoisier's sign, points towards a pancreatic malignancy due to biliary obstruction. Gallstones could cause similar symptoms but would typically not present with a palpable mass. Hepatitis usually does not present with a palpable mass and would have different laboratory findings. Primary biliary cirrhosis typically presents differently with chronic cholestasis without the presence of a palpable mass or a pancreatic lesion.

3. The healthcare provider is preparing to administer a blood transfusion. Which action is most important to ensure client safety?

• A. Check the client's vital signs before starting the transfusion.
• B. Verify the client's identity and blood compatibility.
• C. Administer the blood with normal saline.
• D. Monitor the client for the first 15 minutes of the transfusion.

Correct answer: B

Rationale: Verifying the client's identity and blood compatibility is the most critical step in ensuring client safety during a blood transfusion. This process helps prevent transfusion reactions by confirming that the correct blood product is being administered to the right patient.

4. The client has been prescribed metformin (Glucophage) for type 2 diabetes. Which instruction should the nurse include in discharge teaching?

• A. Take the medication at bedtime.
• B. Take the medication with meals.
• C. Take the medication on an empty stomach.
• D. Take the medication as needed for high blood sugar.

Correct answer: B

Rationale: The correct instruction for taking metformin (Glucophage) is with meals. This helps reduce gastrointestinal side effects and improves the medication's absorption. Taking it on an empty stomach can lead to more adverse effects, so it is essential to take it with food. Option A ('Take the medication at bedtime') is incorrect because metformin should be taken with meals to enhance its effectiveness and reduce side effects. Option C ('Take the medication on an empty stomach') is incorrect as taking metformin on an empty stomach can increase the likelihood of experiencing gastrointestinal issues. Option D ('Take the medication as needed for high blood sugar') is incorrect because metformin is typically taken regularly as prescribed, not just as needed for high blood sugar.

5. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.
