Correct Answer: B

Rationale: The correct answer is B. Rifampin can cause a harmless reddish-orange discoloration of body fluids, including urine. Choice A is not related to rifampin; vision changes are not a common side effect of the medication. Choice C is more relevant to medications that cause photosensitivity reactions, not specifically rifampin. Choice D is incorrect because nausea is a common side effect of rifampin, but it does not warrant immediate discontinuation of the medication.

Correct Answer: B

Rationale: The correct action for the nurse to take when preparing to administer an intermittent tube feeding to a client with a gastrostomy tube is to flush the tube with 30 mL of water before feeding. This step helps ensure the patency of the tube by clearing any blockages or residuals. Choice A is incorrect because flushing after feeding would not prevent clogging before the feeding. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height for the feeding bag is usually recommended to be at or below the level of the stomach to prevent complications like aspiration.

Correct Answer: D

Rationale: The correct answer is D. After cataract surgery, wearing an eye shield at night for 2 weeks is essential to protect the eye during the initial healing period. Choice A is incorrect because significant eye pain should not be expected for the first 2 days after surgery. Choice B is incorrect as bending at the waist can increase intraocular pressure, which should be avoided postoperatively. Choice C is incorrect as there is no need to avoid sleeping on the side of the body that was operated on after cataract surgery.

Correct Answer: A

Rationale: The correct intervention the nurse should include in the care plan for a client with Alzheimer's disease is to provide reality orientation throughout the day. Reality orientation involves helping clients with Alzheimer's disease stay connected to the present, reducing confusion and disorientation. This intervention can help the client maintain a sense of time, place, and person. Choices B, C, and D are incorrect because limiting choices may lead to frustration, group therapy may not always be suitable for clients with Alzheimer's disease, and sensory stimulation activities may not address the core issue of disorientation in Alzheimer's disease.

Correct Answer: A

Rationale: The correct action for the nurse to take when a client with a history of angina reports chest pain is to administer sublingual nitroglycerin every 5 minutes. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart and relieving chest pain associated with angina. Aspirin is often given during a suspected heart attack, not for immediate relief of angina. Deep breathing exercises may be beneficial for anxiety or respiratory conditions but are not the first-line intervention for angina. Oxygen therapy is not the initial treatment for angina unless the client is hypoxic.
