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 expected ECG finding in a patient with hypokalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Widened QRS complexes
• D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

3. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

4. What are the expected findings in a patient experiencing hypokalemia?

• A. Flattened T waves on an ECG
• B. Elevated ST segments
• C. Prominent U waves
• D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

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.
