1. What are the common manifestations of a thrombotic stroke?

• A. Gradual loss of function on one side of the body
• B. Sudden loss of consciousness
• C. Severe headache and confusion
• D. Seizures and convulsions

Correct answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. A thrombotic stroke is characterized by a gradual onset of symptoms due to interrupted blood flow in the brain. This interruption results in manifestations such as weakness, numbness, or paralysis on one side of the body. Choices B, C, and D are incorrect because sudden loss of consciousness, severe headache, confusion, seizures, and convulsions are more commonly associated with conditions other than thrombotic strokes.

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 is the priority action when a healthcare professional misreads a glucose reading and administers excess insulin?

• A. Administer IV glucose
• B. Monitor for hyperglycemia
• C. Monitor for hypoglycemia
• D. Document the incident

Correct answer: C

Rationale: The priority action when a healthcare professional misreads a glucose reading and administers excess insulin is to monitor for hypoglycemia. Excess insulin can lead to dangerously low blood sugar levels (hypoglycemia), which can result in serious complications. Monitoring for hypoglycemia allows for timely identification and intervention to prevent harm. Administering IV glucose may be necessary if hypoglycemia occurs. Monitoring for hyperglycemia is not the priority in this situation, as excess insulin would lower blood sugar levels. Documenting the incident is important for reporting and quality improvement purposes but should not take precedence over ensuring patient safety by monitoring for hypoglycemia.

4. 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.

5. 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.
