1. 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.

2. What are the signs and symptoms of a hemorrhagic stroke?

• A. Sudden severe headache, decreased level of consciousness, and seizures
• B. Loss of consciousness and weakness
• C. Temporary vision loss
• D. Severe chest pain and shortness of breath

Correct answer: A

Rationale: The correct answer is A. A hemorrhagic stroke often presents with a sudden severe headache, decreased level of consciousness, and seizures due to bleeding in the brain. Choice B, loss of consciousness and weakness, is more indicative of an ischemic stroke where a clot blocks blood flow to the brain. Choice C, temporary vision loss, is more commonly seen in conditions like transient ischemic attacks (TIAs) or retinal migraines. Choice D, severe chest pain and shortness of breath, are symptoms more associated with cardiac issues like a heart attack.

3. What are the early signs of hypokalemia on an ECG?

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

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

4. What should be done if a patient experiences abdominal cramping during enema administration?

• A. Lower the height of the enema solution container
• B. Stop the procedure and remove the tubing
• C. Continue the enema at a slower rate
• D. Increase the flow of the enema solution

Correct answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the appropriate action is to lower the height of the enema solution container. This adjustment helps alleviate the cramping by reducing the pressure of the solution entering the colon. Stopping the procedure and removing the tubing (Choice B) is not necessary unless there are other complications. Continuing the enema at a slower rate (Choice C) may not address the immediate discomfort caused by cramping. Increasing the flow of the enema solution (Choice D) can exacerbate the cramping and should be avoided.

5. A client has a right-sided pneumothorax, and a chest tube is inserted. Which finding indicates that the chest drainage system is functioning correctly?

• A. Gentle bubbling in the suction chamber
• B. Crepitus around the insertion site
• C. Constant bubbling in the water seal chamber
• D. Absence of breath sounds on the right side

Correct answer: A

Rationale: In a chest drainage system, gentle bubbling in the suction chamber indicates proper functioning, showing that the system is connected and working effectively to remove air or fluid from the pleural space. Crepitus around the insertion site (Choice B) suggests subcutaneous emphysema, not chest tube functionality. Constant bubbling in the water seal chamber (Choice C) indicates an air leak. Absence of breath sounds on the right side (Choice D) is indicative of the pneumothorax, not the chest tube function.
