1. What ECG changes should be monitored in a patient with hypokalemia?

• A. Flattened T waves and prominent U waves
• B. Elevated ST segments and wide QRS complexes
• C. Tall T waves and flattened QRS complexes
• D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. What does continuous bubbling in the water seal chamber of a chest tube indicate?

• A. An air leak
• B. A blocked chest tube
• C. Normal chest tube function
• D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak in the system. This occurs when air is entering the system through a leak, preventing the lung from fully re-expanding. Choice B, a blocked chest tube, is incorrect as a blocked tube would result in a lack of drainage rather than continuous bubbling. Choice C, normal chest tube function, is incorrect as continuous bubbling signifies an issue. Choice D, continuous drainage from the chest tube, is incorrect as bubbling in the water seal chamber specifically indicates an air leak, not just the presence of drainage.

3. 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.

4. What is the priority dietary modification for a patient with pre-dialysis end-stage kidney disease?

• A. Limit phosphorus intake to 700 mg/day
• B. Increase potassium intake to 3 g/day
• C. Eat three large meals per day
• D. Restrict protein intake to 1 g/kg/day

Correct answer: A

Rationale: The correct answer is A: Limit phosphorus intake to 700 mg/day. In patients with pre-dialysis end-stage kidney disease, restricting phosphorus intake is crucial to manage their condition. Excessive phosphorus can lead to mineral and bone disorders, which are common in kidney disease. Choice B, increasing potassium intake, is not the priority and can be harmful as kidney disease often leads to hyperkalemia. Choice C, eating three large meals per day, is not recommended as smaller, frequent meals are usually better tolerated. Choice D, restricting protein intake to 1 g/kg/day, is important in later stages of kidney disease but is not the priority at the pre-dialysis stage.

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

• A. Avoid NSAIDs
• B. Avoid bright lights
• C. Wear dark glasses while outdoors
• D. Use warm compresses

Correct answer: A

Rationale: The correct teaching to provide to a patient after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to reduce the risk of bleeding post-surgery. Choices B, C, and D are not directly related to post-cataract surgery care. Avoiding bright lights and wearing dark glasses while outdoors may be beneficial for eye comfort but are not specific postoperative instructions. Using warm compresses is also not a standard teaching after cataract surgery.
