1. What should a healthcare provider monitor for in a patient with HIV and a CD4 T-cell count below 180 cells/mm3?

A. Monitor for signs of infection
B. Monitor for anemia
C. Monitor for dehydration
D. Monitor for bleeding

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm3 indicates severe immunocompromise in a patient with HIV. Monitoring for signs of infection is crucial because the patient is at high risk of developing opportunistic infections. Anemia (choice B), dehydration (choice C), and bleeding (choice D) are not directly associated with a low CD4 T-cell count in patients with HIV.

2. 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.

3. What are the expected findings in a patient with hypokalemia?

A. Cardiac dysrhythmias
B. Seizures and confusion
C. Bradycardia
D. Muscle weakness

Correct answer: A

Rationale: The correct answer is A: Cardiac dysrhythmias. Hypokalemia is commonly associated with cardiac dysrhythmias due to the role potassium plays in maintaining proper electrical conduction in the heart. Choices B, C, and D are incorrect. While hypokalemia can lead to muscle weakness, the most critical and life-threatening manifestation is cardiac dysrhythmias. Seizures and confusion are more commonly associated with other electrolyte imbalances, such as hyponatremia. Bradycardia is not a typical finding in hypokalemia, as it tends to cause tachycardia or other arrhythmias.

4. What ECG changes are seen in hypokalemia?

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

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

5. What are the expected ECG changes in hypokalemia?

A. Flattened T waves
B. ST elevation
C. Wide QRS complex
D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
