1. A nurse misreads a blood glucose level and administers excess insulin. What should the nurse monitor for?

A. Monitor for hyperglycemia
B. Monitor for hypoglycemia
C. Administer glucose IV
D. Monitor for increased thirst

Correct answer: B

Rationale: The correct answer is to monitor for hypoglycemia. Excess insulin can lead to low blood glucose levels, causing hypoglycemia. Symptoms of hypoglycemia include sweating, trembling, dizziness, confusion, and in severe cases, loss of consciousness. Options A, C, and D are incorrect because administering excess insulin would not lead to hyperglycemia or increased thirst, and administering glucose IV would exacerbate the issue by further lowering blood glucose levels.

2. 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.

3. What does continuous bubbling in the water seal chamber of a chest tube indicate?

A. An air leak
B. Drainage in the chest tube
C. A blocked chest tube
D. Normal chest tube function

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This signifies that air is escaping from the patient's pleural space into the chest tube system rather than being evacuated properly. An air leak can lead to lung collapse or pneumothorax and requires immediate attention. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because continuous bubbling does not indicate normal chest tube function, drainage in the chest tube, or a blocked chest tube.

4. What are the expected symptoms in a patient with 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. Loss of sensation in the affected limb

Correct answer: A

Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.

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

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

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.
