1. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

2. What is the priority action if a patient experiences hypoglycemia after an insulin dose?

• A. Check the patient's blood glucose level
• B. Administer IV dextrose
• C. Document the incident
• D. Continue monitoring the patient

Correct answer: A

Rationale: The priority action when a patient experiences hypoglycemia after an insulin dose is to check the patient's blood glucose level. This is crucial to confirm hypoglycemia before initiating any treatment. While administering IV dextrose may be necessary if the patient's blood glucose level is critically low, confirming hypoglycemia is essential to guide appropriate interventions. Documenting the incident is important for documentation purposes but is not the immediate priority when the patient's safety is at risk. Continuing to monitor the patient is essential, but it should follow the confirmation and initial management of hypoglycemia.

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 dietary recommendations should be provided for a patient with pre-dialysis end-stage kidney disease?

• A. Reduce phosphorus intake to 700 mg/day
• B. Increase sodium intake
• C. Restrict protein intake to 0.55-0.60 g/kg/day
• D. Limit potassium-rich foods

Correct answer: A

Rationale: The correct recommendation for a patient with pre-dialysis end-stage kidney disease is to reduce phosphorus intake to 700 mg/day. Excessive phosphorus can be harmful to individuals with kidney disease as the kidneys may not be able to effectively remove it from the body. Choices B, C, and D are incorrect. Increasing sodium intake is generally not recommended for patients with kidney disease as it can lead to fluid retention and high blood pressure. Restricting protein intake is important in later stages of kidney disease, but for pre-dialysis end-stage kidney disease, protein intake should be individualized based on the patient's condition. Limiting potassium-rich foods is more relevant for patients with advanced kidney disease or those on dialysis, as impaired kidney function can lead to high potassium levels in the blood.

5. What precaution should be advised to a patient following a cataract surgery?

• A. Wear dark glasses while outdoors
• B. Avoid NSAIDs
• C. Use warm compresses
• D. Apply cold packs

Correct answer: A

Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.
