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 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.

3. What are the characteristics of a thrombotic stroke?

• A. Gradual onset over minutes to hours
• B. Numbness on one side of the body
• C. Associated with a loss of consciousness
• D. Associated with seizures and convulsions

Correct answer: A

Rationale: The correct answer is A. Thrombotic strokes typically have a gradual onset over minutes to hours as they result from a clot obstructing blood flow. Choice B, numbness on one side of the body, is more commonly associated with an ischemic stroke rather than specifically a thrombotic stroke. Choice C, loss of consciousness, is not a defining characteristic of a thrombotic stroke. Choice D, seizures and convulsions, are more commonly seen in hemorrhagic strokes rather than thrombotic strokes.

4. What is the preferred electrical intervention for a patient with ventricular tachycardia and a pulse?

• A. Synchronized cardioversion
• B. Defibrillation
• C. Medication administration
• D. Pacing

Correct answer: A

Rationale: In a patient with ventricular tachycardia and a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat unstable tachyarrhythmias like ventricular tachycardia with a pulse. Choice B, defibrillation, is used for pulseless ventricular tachycardia or ventricular fibrillation. Choice C, medication administration, may not provide immediate correction for unstable ventricular tachycardia. Choice D, pacing, is not the first-line treatment for ventricular tachycardia with a pulse.

5. 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.
