A nurse is assisting with teaching a client about the sleep-wake cycle. The nurse should include that which of the following factors can interfere with the sleep-wake cycle?

The correct answer is D. Wash the client’s body. This is a standard part of postmortem care to ensure the body is clean and presentable for the family and any further procedures.

Choice A reason:

Remove the client’s dentures. This statement is incorrect because dentures should be left in place to maintain the shape of the face and ensure a natural appearance for viewing by the family.

Choice B reason:

Increase the lights in the client’s room. This statement is incorrect because dim lighting is often preferred to create a calm and respectful environment for the family.

Choice C reason:

Place the head of the client’s bed flat. This statement is incorrect because the head should be elevated to prevent discoloration and pooling of blood.

Choice D reason:

Wash the client’s body. This is correct as it is a standard part of postmortem care to ensure the body is clean and presentable for the family and any further procedures.

Choice A reason : Dry mouth, also known as xerostomia, is a common side effect of diphenhydramine, an antihistamine used to treat insomnia among other conditions. It occurs because diphenhydramine has anticholinergic properties, which means it inhibits the action of the neurotransmitter acetylcholine. This inhibition can reduce saliva production, leading to a feeling of dryness in the mouth.

Choice B reason : Hypertension, or high blood pressure, is not a typical side effect of diphenhydramine. While some medications, particularly decongestants, can raise blood pressure, diphenhydramine does not usually have this effect. However, individuals with pre-existing heart conditions should consult a healthcare provider before using it.

Choice C reason : Memory loss is not commonly listed as a side effect of diphenhydramine. However, because it can cause drowsiness and has sedative effects, it may lead to temporary forgetfulness or confusion, especially in older adults or when taken in higher doses.

Choice D reason : 'Medications' is not an adverse reaction but rather a general term for drugs used to diagnose, treat, or prevent illness. In the context of diphenhydramine, it would be more appropriate to discuss specific side effects or adverse reactions related to its use.
