1. What is a characteristic sign of hypokalemia on an ECG?

• A. Flattened T waves
• B. ST elevation
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

2. What intervention should be done if continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Replace the chest tube system
• C. Clamp the chest tube
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate intervention is to tighten the connections of the chest tube system. This step helps address an air leak in the system, which could compromise its effectiveness. Choice B (Replace the chest tube system) is not the initial step and may be unnecessary if the issue can be resolved by tightening connections. Choice C (Clamp the chest tube) is incorrect as clamping the chest tube could lead to a dangerous increase in pressure within the system. Choice D (Continue monitoring the chest tube) is also not the best immediate action to take when continuous bubbling is present, as prompt intervention is needed to prevent complications.

3. What are the expected signs of increased intracranial pressure (IICP)?

• A. Restlessness, confusion, irritability
• B. Severe headache and confusion
• C. Elevated blood pressure and bradycardia
• D. Bradycardia and altered pupil response

Correct answer: A

Rationale: The correct answer is A: Restlessness, confusion, irritability. These are early signs of increased intracranial pressure (IICP) and require prompt intervention. Restlessness, confusion, and irritability are indicative of the brain's attempt to compensate for the rising pressure. Choice B is incorrect because severe headache alone is not specific to IICP and can be present in various conditions. Choice C is incorrect because elevated blood pressure is not a common sign of IICP; instead, hypertension may be present in the compensatory stage. Choice D is incorrect as bradycardia and altered pupil response are signs of advanced IICP, not early signs. Monitoring and recognizing these early signs are crucial for timely intervention and preventing further complications.

4. What should be monitored in a patient receiving insulin who is at risk for hypoglycemia?

• A. Monitor blood glucose levels
• B. Monitor for respiratory distress
• C. Monitor for hypertension
• D. Monitor for hyperkalemia

Correct answer: A

Rationale: Corrected Question: In a patient receiving insulin who is at risk for hypoglycemia, monitoring blood glucose levels is crucial. This helps in preventing and identifying hypoglycemia promptly. Choice B, monitoring for respiratory distress, is not directly related to hypoglycemia caused by insulin. Choice C, monitoring for hypertension, is not typically associated with hypoglycemia. Choice D, monitoring for hyperkalemia, is not a common concern in patients receiving insulin who are at risk for hypoglycemia.

5. What teaching should be provided to a patient following cataract surgery?

• A. Avoid NSAIDs
• B. Wear dark glasses outdoors
• C. Creamy white drainage is normal
• D. Avoid alcohol

Correct answer: A

Rationale: The correct teaching to provide to a patient following cataract surgery is to avoid NSAIDs. NSAIDs should be avoided post-cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses outdoors, is important to protect the eyes from bright light but is not directly related to medication use. Choice C, stating that creamy white drainage is normal, is incorrect as drainage should be monitored for excessive redness, swelling, or pain. Choice D, avoiding alcohol, is not a direct post-cataract surgery teaching point related to medication use.
