A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

Correct Answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.

Correct Answer: C

Rationale: The correct action for the nurse to take is to administer naloxone if the client's respiratory rate falls below 10/min. Naloxone is used to reverse opioid-induced respiratory depression, which is a life-threatening situation. Monitoring the client's blood pressure every 4 hours (Choice A) is not the priority in this scenario as respiratory depression requires immediate attention. Asking the client to rate their pain every 2 hours (Choice B) is important for pain management but addressing respiratory depression takes precedence. Evaluating the client's use of the PCA every 4 hours (Choice D) is a routine nursing intervention but does not directly address the urgent need to reverse respiratory depression in this case.

Correct Answer: B

Rationale: The correct answer is B. A blood pressure of 110/70 mm Hg is a finding that the nurse should report to the provider when caring for a client with heart failure receiving digoxin. Digoxin can cause hypotension, so a low blood pressure reading should be reported promptly to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and would not require immediate reporting. A heart rate of 60/min is considered normal, but any further decrease should be monitored. A serum potassium level of 4 mEq/L is also within the normal range. A blood pressure of 120/80 mm Hg is typically considered normal as well.

Correct Answer: B

Rationale: The correct answer is B. A heart rate of 68/min is lower than expected and should be reported as it may indicate digoxin toxicity. Choices A, C, and D are within normal limits for a client receiving furosemide for heart failure and do not require immediate reporting. Weight loss may be expected due to diuretic therapy, a potassium level of 3.8 mEq/L is within the normal range, and a urine output of 60 mL/hr indicates adequate renal perfusion.

Correct Answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.
