1. What ECG changes are seen with hyperkalemia?

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.

2. What is the first-line treatment for a patient experiencing wheezing and coughing due to an allergic reaction?

Correct answer: A

Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction as it quickly opens the airways, providing rapid relief. Choice B, Methylprednisolone 100 mg IV, is a systemic corticosteroid that may be used in severe cases to reduce inflammation but is not the initial treatment for acute wheezing. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that is more commonly used for prophylaxis rather than acute relief in allergic conditions. Choice D, Aminophylline 500 mg IV, is a bronchodilator that is less commonly used now due to its narrow therapeutic window and potential for toxicity, making it less preferred than Albuterol for initial treatment of wheezing.

3. What dietary teaching should be provided to a patient with pre-dialysis end-stage kidney disease?

Correct answer: A

Rationale: The correct answer is to limit phosphorus intake to 700 mg/day for a patient with pre-dialysis end-stage kidney disease. Excess phosphorus can lead to complications such as bone and heart issues in these patients. Increasing protein intake (Choice B) is generally not recommended as it can lead to increased waste production that the kidneys may struggle to eliminate. Restricting sodium intake (Choice C) is important for managing blood pressure, but the recommendation is usually higher than 1 g/day. Increasing potassium intake (Choice D) is not typically advised in patients with kidney disease, as they often need to limit potassium due to impaired kidney function.

4. What is the first medication to administer for a patient experiencing wheezing due to an allergic reaction?

Correct answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is the first-line medication for wheezing due to its rapid bronchodilatory effects. Choice B, Cromolyn, is used more for preventing allergic reactions rather than acute relief of wheezing. Choice C, Methylprednisolone, is a steroid used for its anti-inflammatory effects and is not the initial choice for acute relief of wheezing. Choice D, Aminophylline, is a bronchodilator but is not the first-line treatment for wheezing due to allergic reactions.

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

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.
