Nursing Elites

1. A client with diabetes mellitus is scheduled for surgery. What is the most important preoperative instruction the nurse should provide?

• A. Take your insulin as usual
• B. Do not eat or drink after midnight
• C. Monitor your blood glucose closely
• D. Bring your glucose meter to the hospital

Correct answer: B

Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.

2. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

3. A client is admitted to the hospital with a diagnosis of Pneumonia. Which intervention should the nurse implement to prevent complications associated with Pneumonia?

• A. Encourage mobilization and ambulation
• B. Encourage energy conservation with complete bed rest
• C. Provide humidified oxygen via nasal cannula
• D. Restrict oral (PO) and intravenous fluids

Correct answer: A

Rationale: The correct intervention to prevent complications associated with pneumonia is to encourage mobilization and ambulation. These activities help prevent complications such as atelectasis by promoting lung expansion. Encouraging energy conservation with complete bed rest (Choice B) is not ideal as it can lead to complications like muscle weakness and decreased lung expansion. Providing humidified oxygen via nasal cannula (Choice C) is important in pneumonia treatment but does not directly prevent complications associated with pneumonia itself. Restricting oral (PO) and intravenous fluids (Choice D) is not recommended as adequate hydration is crucial for pneumonia patients to maintain respiratory function and overall health.

4. A client with a history of seizure disorder who is receiving phenytoin (Dilantin) is being discharged. Which instruction should the nurse provide?

• A. Take the medication at bedtime.
• B. Monitor drug levels regularly.
• C. Avoid alcohol while taking this medication.
• D. Take the medication at the same time every day.

Correct answer: B

Rationale: The correct answer is to instruct the client to monitor drug levels regularly. This is crucial for phenytoin (Dilantin) to ensure that the medication levels are within the therapeutic range and to prevent toxicity. Choice A, taking the medication at bedtime, is not specifically required for phenytoin administration. Choice C, avoiding alcohol, is generally a good practice with medications but is not as critical as monitoring drug levels for phenytoin. Choice D, taking the medication at the same time every day, is important for consistency but does not address the specific monitoring needs of phenytoin.

5. The nurse is changing the colostomy bag for a client who is complaining of leakage of diarrheal stool under the disposable ostomy bag. What action should the nurse implement to prevent leakage?

• A. Place a 4x4 wick in the stoma opening
• B. Apply a layer of zinc oxide ointment to the perimeter of the stoma
• C. Cut the bag opening to the measurement of the stoma size
• D. Administer a PRN antidiarrheal agent

Correct answer: C

Rationale: To prevent leakage of stool under the disposable ostomy bag, the nurse should cut the bag opening to the measurement of the stoma size. This action ensures a proper fit, which is crucial in preventing leaks that can lead to skin irritation and compromise stoma care. Placing a 4x4 wick in the stoma opening or applying zinc oxide ointment may not address the issue of leakage effectively. Administering a PRN antidiarrheal agent is not directly related to preventing leakage caused by an ill-fitting ostomy bag.
