1. What medication should be given first to a patient experiencing wheezing and coughing due to an allergic reaction?

• A. Albuterol 3 ml via nebulizer
• B. Cromolyn via nebulizer
• C. Aminophylline IV
• D. Methylprednisolone 100 mg IV

Correct answer: A

Rationale: The correct answer is Albuterol 3 ml via nebulizer. Albuterol is a bronchodilator that helps relieve wheezing and coughing by opening up the airways, making it the first-line treatment for allergic reactions presenting with these symptoms. Cromolyn and aminophylline are not typically used as first-line treatments for acute allergic reactions with wheezing and coughing. Methylprednisolone, a corticosteroid, may be beneficial for inflammation in the setting of an allergic reaction but is not the initial medication of choice to address wheezing and coughing.

2. What is the priority action if a patient experiences hypoglycemia after an insulin dose?

• A. Check the patient's blood glucose level
• B. Administer IV dextrose
• C. Document the incident
• D. Continue monitoring the patient

Correct answer: A

Rationale: The priority action when a patient experiences hypoglycemia after an insulin dose is to check the patient's blood glucose level. This is crucial to confirm hypoglycemia before initiating any treatment. While administering IV dextrose may be necessary if the patient's blood glucose level is critically low, confirming hypoglycemia is essential to guide appropriate interventions. Documenting the incident is important for documentation purposes but is not the immediate priority when the patient's safety is at risk. Continuing to monitor the patient is essential, but it should follow the confirmation and initial management of hypoglycemia.

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. A patient with a chest tube has continuous bubbling in the water seal chamber. What does this indicate?

• A. An air leak
• B. A blocked chest tube
• C. Drainage from the site
• D. Blood clot in the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This situation requires immediate attention to prevent complications such as lung collapse. A blocked chest tube would typically result in absent or fluctuating bubbling. Drainage from the site would be observed in the collection chamber, not the water seal chamber. A blood clot in the chest tube would lead to cessation of drainage.

5. 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.
