Which of the following is the most concerning electrolyte imbalance for a patient on furosemide?
- A. Hypokalemia
- B. Hyperkalemia
- C. Hyponatremia
- D. Hypercalcemia
Correct Answer: A
Rationale: The correct answer is Hypokalemia. Furosemide, a loop diuretic, can lead to potassium depletion in the body, causing hypokalemia. This is a significant concern as low potassium levels can result in cardiac arrhythmias and other serious complications. Hyperkalemia (Choice B) is unlikely to occur as a result of furosemide use. Hyponatremia (Choice C) is more commonly associated with thiazide diuretics. Hypercalcemia (Choice D) is not typically linked to furosemide use.

A nurse is caring for a client who is receiving continuous enteral feeding through a nasogastric tube. Which of the following actions should the nurse take to prevent aspiration?
- A. Flush the tube with 30 mL of water every 4 hours.
- B. Position the client on the left side during feedings.
- C. Elevate the head of the bed to 45 degrees during feedings.
- D. Check gastric residual every 2 hours.
Correct Answer: C
Rationale: To prevent aspiration in clients receiving continuous enteral feedings, the nurse should elevate the head of the bed to 45 degrees. This position helps reduce the risk of regurgitation and aspiration. Flushing the tube with water every 4 hours (Choice A) is important for maintaining tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (Choice B) is not specifically related to preventing aspiration in this context. Checking gastric residual every 2 hours (Choice D) is important to assess feeding tolerance but does not directly prevent aspiration.
A nurse is providing discharge teaching to a client who has a new diagnosis of diabetes mellitus. Which of the following client statements indicates a need for further teaching?
- A. I will check my blood glucose level once a week.
- B. I will eat a snack if my blood glucose level is above 200 mg/dL.
- C. I will take my insulin as prescribed, even when I am feeling well.
- D. I will avoid physical activity if my blood glucose level is below 100 mg/dL.
Correct Answer: B
Rationale: The correct answer is B. Clients should eat a snack when their blood glucose level is low, typically below 70-100 mg/dL, not when it is high. Eating a snack when the blood glucose level is above 200 mg/dL can exacerbate hyperglycemia. Choice A is correct as checking blood glucose levels regularly is important in managing diabetes. Choice C is also correct as adherence to prescribed insulin therapy is crucial. Choice D is incorrect as physical activity can help lower blood glucose levels, especially when they are above the target range.
What is the correct method to teach a patient about self-administration of insulin?
- A. Inject into the upper arm
- B. Rotate injection sites
- C. Use a 45-degree angle for injection
- D. Use a 90-degree angle for injection
Correct Answer: D
Rationale: The correct method to teach a patient about self-administration of insulin is to use a 90-degree angle for injection. This angle ensures proper subcutaneous administration of insulin, which is essential for effective absorption. Injecting into the upper arm (Choice A) is not recommended for insulin administration. While rotating injection sites (Choice B) is important to prevent lipodystrophy, the angle of injection is crucial for proper insulin delivery. Using a 45-degree angle (Choice C) is more suitable for intramuscular injections, not for subcutaneous insulin injections.
A client with hypertension is receiving discharge teaching from a nurse on managing blood pressure at home. Which of the following instructions should the nurse include?
- A. Take medication at bedtime.
- B. Check blood pressure once a week.
- C. Use a blood pressure cuff that fits snugly around the arm.
- D. Stop taking medication once blood pressure is within the normal range.
Correct Answer: C
Rationale: The correct answer is C: 'Use a blood pressure cuff that fits snugly around the arm.' Using a properly fitting cuff is essential for accurate blood pressure measurements. Choice A is incorrect because the timing of medication administration should be individualized and not specified in the question. Choice B is incorrect as checking blood pressure once a week may not provide sufficient monitoring for a client with hypertension. Choice D is incorrect because stopping medication abruptly once blood pressure is normal can lead to rebound hypertension and complications.
A nurse is assessing a client who has pneumonia. Which of the following findings should the nurse report to the provider?
- A. Crackles in the lung bases
- B. Oxygen saturation of 95%
- C. Heart rate of 88/min
- D. Frequent productive cough
Correct Answer: A
Rationale: The correct answer is A: Crackles in the lung bases. In a client with pneumonia, crackles in the lung bases can indicate fluid accumulation, suggesting worsening respiratory status. This finding should be reported to the provider for further evaluation and management. Choice B, an oxygen saturation of 95%, is within the normal range and does not require immediate reporting. Choice C, a heart rate of 88/min, is also within normal limits and does not indicate an urgent need for intervention. Choice D, a frequent productive cough, is a common symptom in pneumonia and may not require immediate reporting unless it is severe or worsening. Therefore, crackles in the lung bases are the most concerning finding that warrants prompt attention.
