1. What is the primary concern in a patient with a low CD4 T-cell count in HIV?

A. Increased risk of infection
B. Increased risk of bleeding
C. Decreased immunity leading to opportunistic infections
D. Increased risk of cardiac complications

Correct answer: A

Rationale: The correct answer is A: Increased risk of infection. In HIV patients with a low CD4 T-cell count, the primary concern is the increased susceptibility to infections due to compromised immunity. This compromised immune system can lead to various infections, making infection control crucial. Choice B, increased risk of bleeding, is not directly associated with a low CD4 count in HIV. Option C, decreased immunity leading to opportunistic infections, conveys a similar concern as the correct answer but lacks specificity. Choice D, increased risk of cardiac complications, is not typically the primary concern in HIV patients with a low CD4 count, as infections and opportunistic diseases pose more immediate threats to health.

2. A patient with GERD is receiving dietary teaching from a nurse. What should the nurse recommend?

A. Avoid mint and pepper
B. Increase fluid intake before meals
C. Eat three large meals per day
D. Avoid drinking water with meals

Correct answer: A

Rationale: The correct recommendation for a patient with GERD is to avoid foods like mint and pepper, as these can help reduce gastric acid secretion and alleviate symptoms. Mint and pepper are known to relax the lower esophageal sphincter, leading to increased reflux. Increasing fluid intake before meals (choice B) may worsen GERD symptoms by distending the stomach. Eating three large meals per day (choice C) can also aggravate GERD because large meals can lead to increased gastric pressure and reflux. Avoiding drinking water with meals (choice D) is generally recommended for GERD; however, the most crucial advice in this case is to avoid mint and pepper for better symptom management.

3. What ECG changes are seen with hyperkalemia?

A. Flattened T waves
B. Elevated ST segments
C. Prominent U waves
D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

4. What precaution should be advised to a patient following a cataract surgery?

A. Wear dark glasses while outdoors
B. Avoid NSAIDs
C. Use warm compresses
D. Apply cold packs

Correct answer: A

Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.

5. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

A. Defibrillation
B. Synchronized cardioversion
C. Pacing
D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.
