Nursing Elites

1. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

2. The nurse is caring for a client with a spinal cord injury. Which intervention should the nurse implement to prevent autonomic dysreflexia?

• A. Restrict the client's fluid intake.
• B. Keep the client's room warm.
• C. Ensure the client's bladder is emptied regularly.
• D. Limit the client's intake of high-fiber foods.

Correct answer: C

Rationale: To prevent autonomic dysreflexia in clients with spinal cord injuries, it is crucial to ensure the client's bladder is emptied regularly. Bladder distention is a common trigger for autonomic dysreflexia in these clients. Keeping the bladder empty helps prevent the complications associated with autonomic dysreflexia, such as dangerously high blood pressure. Choices A, B, and D are incorrect. Restricting fluid intake can lead to dehydration, keeping the room warm is not directly related to preventing autonomic dysreflexia, and limiting high-fiber foods is not a primary intervention for this condition.

3. Why is a low-protein diet recommended for a client with hepatic encephalopathy?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Increased ammonia levels
• D. Electrolyte imbalance

Correct answer: C

Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.

4. A client with newly diagnosed diabetes mellitus is receiving teaching on foot care. Which instruction should the nurse include?

• A. Walk barefoot whenever possible to toughen your feet.
• B. Soak your feet in hot water daily to improve circulation.
• C. Trim your toenails straight across to prevent ingrown toenails.
• D. Use a heating pad to keep your feet warm.

Correct answer: C

Rationale: Correctly trimming toenails straight across is crucial in preventing ingrown toenails and potential infections in individuals with diabetes. Ingrown toenails can lead to complications, so it is essential for diabetic clients to practice proper nail care to avoid these issues. Choices A, B, and D are incorrect. Walking barefoot can increase the risk of foot injuries, soaking feet in hot water can cause burns or skin damage, and using a heating pad can lead to burns or injuries due to decreased sensation in the feet, which is common in diabetes.

5. A client from a nursing home is admitted with urinary sepsis and has a single-lumen, peripherally-inserted central catheter (PICC). Four medications are prescribed for 9:00 a.m. and the nurse is running behind schedule. Which medication should the nurse administer first?

• A. Piperacillin/tazobactam (Zosyn) in 100 ml D5W, IV over 30 minutes q8 hours.
• B. Vancomycin (Vancocin) 1 gm in 250 ml D5W, IV over 90 minutes q12 hours.
• C. Pantoprazole (Protonix) 40 mg PO daily.
• D. Enoxaparin (Lovenox) 40 mg subq q24 hours.

Correct answer: A

Rationale: In a patient with urinary sepsis, administering Piperacillin/tazobactam first is crucial as it is an antibiotic that directly targets the infection. Addressing the infection promptly is essential to prevent its progression and complications. Vancomycin, Pantoprazole, and Enoxaparin are important medications for the patient's overall treatment plan, but in this scenario, the antibiotic should take precedence due to the urgency of managing the sepsis.
