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 signs indicate increased intracranial pressure (IICP)?

• A. Restlessness, irritability, and confusion
• B. Sudden onset of seizures
• C. Bradycardia and altered pupil response
• D. Loss of consciousness

Correct answer: A

Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.

3. What are the dietary recommendations for a patient with pre-dialysis end-stage kidney disease?

• A. Reduce phosphorus intake to 700 mg/day
• B. Limit sodium intake to 1,500 mg/day
• C. Restrict protein intake to 0.55-0.60 g/kg/day
• D. Increase protein intake

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. High phosphorus levels can be harmful to individuals with kidney disease as the kidneys may not be able to filter it effectively. While limiting sodium intake to 1,500 mg/day and restricting protein intake to 0.55-0.60 g/kg/day are important in managing kidney disease, the primary concern for this patient population is to control phosphorus levels. Increasing protein intake is not recommended as it can put additional strain on the kidneys. Therefore, option A is the most appropriate recommendation in this scenario.

4. A nurse is teaching a client who has type 1 DM about hypoglycemia. Which of the following statements by the client indicates an understanding of the teaching?

• A. Exercise reduces the risk for hypoglycemia.
• B. I can skip my insulin when I don't eat.
• C. I can drink 4 oz of soda if my blood sugar is low.
• D. Diabetic pills don't cause hypoglycemia; only insulin does.

Correct answer: C

Rationale: The client can correct any development of hypoglycemia with a quick intake of glucose. The client should have 15 g carbohydrates on hand to treat hypoglycemic episodes, like 4 oz of regular soda.

5. What is the initial nursing action for a patient with a chest tube found to have an air leak?

• A. Check the tube connections
• B. Replace the chest tube
• C. Remove and reinsert the chest tube
• D. Document the incident

Correct answer: A

Rationale: When a patient with a chest tube is found to have an air leak, the priority action for the nurse is to check the tube connections. This step helps identify the source of the air leak, which can be caused by loose or disconnected tube connections. Once the source of the leak is identified and addressed, further interventions may be necessary. Replacing or removing and reinserting the chest tube should not be the initial response unless there are specific indications for these actions. Documenting the incident is important but comes after addressing the immediate concern of the air leak.
