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 answer is A: 'Take a tablet every 5 minutes for pain relief, up to three doses.' Nitroglycerin sublingual tablets are used to relieve chest pain or to prevent chest pain before activities known to cause angina. The tablets should be taken every 5 minutes for pain relief, up to three doses, as prescribed. Choice B is incorrect because nitroglycerin sublingual tablets should be placed under the tongue until they dissolve, not taken with water. Choice C is incorrect because nitroglycerin sublingual tablets should not be chewed but placed under the tongue for absorption. Choice D is incorrect because nitroglycerin tablets should be stored in their original container at room temperature away from light and moisture.

Correct Answer: D

Rationale: Elevating the client's right arm on a pillow is essential post-mastectomy to reduce swelling and promote circulation. Placing the client in the supine position may not be comfortable or ideal after a mastectomy. Encouraging the client to lift objects with the right arm can strain the surgical site and hinder healing. Measuring the client's blood pressure on the right arm should be avoided to prevent disruption to the area and inaccurate readings.

Correct Answer: B

Rationale: The correct answer is B because insulin glargine should be stored in the refrigerator after opening to maintain its potency. Choice A is incorrect as insulin glargine should not be mixed with other insulins. Choice C is incorrect because insulin glargine is typically taken once a day. Choice D is incorrect because insulin glargine is usually taken regardless of blood glucose levels.

Correct Answer: B

Rationale: The correct answer is B. Clients taking digoxin should check their pulse before each dose to ensure it is within the appropriate range. Option A is incorrect because stopping the medication based solely on a heart rate below 80/min is not recommended. Option C is incorrect as having a pulse above 100/min doesn't necessarily indicate a need to stop digoxin. Option D is incorrect because digoxin should not be taken with an antacid as it can interfere with its absorption.

Correct Answer: B

Rationale: The correct answer is B. It is crucial for clients to complete the entire course of antibiotics as prescribed, even if symptoms improve. This helps to ensure that the infection is fully treated and reduces the risk of developing antibiotic resistance. Choice A is incorrect because stopping the medication when symptoms disappear can lead to incomplete treatment. Choice C is incorrect as amoxicillin can be taken with or without food. Choice D is incorrect because taking amoxicillin with milk can decrease its absorption.
