1. What ECG changes are seen with hyperkalemia?

• 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 ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

2. 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.

3. What intervention is needed when continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Replace 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 action can help resolve an air leak, which is often the cause of continuous bubbling in the water seal chamber. Clamping the chest tube (choice B) is not recommended as it can lead to a dangerous increase in pressure within the chest. Replacing the chest tube (choice C) is not the initial intervention unless there are other indications to do so. Simply monitoring the chest tube (choice D) without taking corrective action will not address the underlying issue of the air leak causing continuous bubbling.

4. What lab value should be prioritized for a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. Serum albumin levels
• C. White blood cell count
• D. Hemoglobin levels

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm3 should be prioritized for a patient with HIV. This value is crucial as it indicates severe immunocompromise in HIV-infected individuals. Monitoring CD4 T-cell count helps assess the status of the immune system and guides treatment decisions. Serum albumin levels (choice B) may reflect the patient's nutritional status and overall health but are not as specific to HIV disease progression. White blood cell count (choice C) and hemoglobin levels (choice D) can be affected by various factors and are not as directly linked to HIV management as the CD4 T-cell count in this context.

5. What should the nurse do if a patient experiences abdominal cramping during enema administration?

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

Correct answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the nurse should lower the height of the solution container. This adjustment can help alleviate the cramping by reducing the speed and pressure of the solution entering the colon. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in extreme cases but is not the initial step. Continuing the enema at a slower rate (Choice D) may not effectively address the cramping, making it less optimal than lowering the height of the solution container.
