A nurse is assisting in the care of a client who has a pulmonary embolism and is experiencing dyspnea. Which of the following actions should the nurse take first?

The correct answer is choice A, participate in reminiscence therapy with the client. This is an effective intervention for individuals with Alzheimer's disease. It involves encouraging the client to discuss past experiences and events. It has been shown to improve mood, decrease agitation, and increase communication skills. The reminiscence therapy should be individualized and tailored to the client's interests and abilities.

1. Raising the four side rails on the client's bed is not the correct answer because this could cause harm to the client by restricting their mobility and independence.
2. Alternating the client's daily routine is not the correct answer because individuals with Alzheimer's disease benefit from a consistent routine, which helps them to feel more secure and less anxious.
3. Keeping the lights dimmed is not the correct answer because it can be disorienting and confusing for clients with Alzheimer's disease, who need adequate lighting to distinguish their surroundings.

The correct answer is choice A. Auscultate the client's abdomen for bowel sounds. This is the first action the nurse should take because it provides information about the client's bowel motility and function. Opioid medications can decrease bowel motility and cause constipation. The nurse should assess the client's abdomen before implementing any interventions.

• Choice B is not correct because providing privacy and a set time to defecate is a nonpharmacological intervention that can help prevent constipation, but it is not the first action the nurse should take.
• Choice C is not correct because administering a fiber-based laxative is a pharmacological intervention that can help treat constipation, but it is not the first action the nurse should take. The nurse should also consider the client's fluid intake and preference before giving a laxative.
• Choice D is not correct because encouraging the client to increase oral intake of fluids is a nonpharmacological intervention that can help prevent constipation, but it is not the first action the nurse should take. The nurse should also consider the client's fluid balance and medical condition before giving fluids.
