1. What is the priority action for a patient experiencing chest pain from acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Administer aspirin
• C. Obtain IV access
• D. Check cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This medication helps to dilate the blood vessels, reduce the workload on the heart, and improve blood flow to the heart muscle, providing immediate relief for chest pain in acute coronary syndrome. Administering aspirin is also crucial in the early management of acute coronary syndrome to prevent further clot formation. However, in terms of immediate symptom relief, nitroglycerin takes precedence over aspirin. Obtaining IV access is important for administering medications and fluids but is not the priority over providing immediate relief for chest pain. Checking cardiac enzymes is essential for diagnosing acute coronary syndrome but is not the immediate priority when a patient is experiencing chest pain.

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. A patient diagnosed with hypokalemia is at risk for which condition?

• A. Cardiac dysrhythmias
• B. Muscle weakness
• C. Seizures
• D. Bradycardia

Correct answer: A

Rationale: Patients diagnosed with hypokalemia are at risk for cardiac dysrhythmias due to low potassium levels. Hypokalemia can lead to abnormalities in the electrical conduction system of the heart, potentially causing irregular heart rhythms. Muscle weakness (Choice B) is a symptom commonly associated with hypokalemia, but the question asks about conditions the patient is at risk for, not specific symptoms. Seizures (Choice C) are not typically associated with hypokalemia; they are more commonly linked with conditions such as epilepsy. Bradycardia (Choice D) refers to a slow heart rate, which is not a typical risk associated with hypokalemia; instead, tachycardia (fast heart rate) is more commonly observed in patients with low potassium levels.

4. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

5. What lab value should be prioritized for monitoring in a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. Hemoglobin levels
• C. Serum albumin levels
• D. White blood cell count

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring CD4 T-cell count is crucial in patients with HIV as it reflects the status of their immune system. A CD4 count below 200 cells/mm3 is indicative of severe immunocompromise, necessitating close monitoring and potential intervention. Choices B, C, and D are less specific to HIV management and do not directly reflect the immune status in these patients. Hemoglobin levels are more relevant for assessing anemia, serum albumin levels for nutritional status, and white blood cell count for overall immune response, but none are as directly tied to HIV disease progression as the CD4 T-cell count.
