A nurse is assisting with teaching a client about over-the-counter medications used to treat insomnia. The nurse should include that which of the following is an adverse reaction of diphenhydramine?
Dry mouth
Hypertension
Memory loss
Medications
The Correct Answer is A
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.

Correct Answer is B
Explanation
Choice A reason : Going to bed at the same time every night, even when not feeling tired, can help regulate the body's clock and aid in falling asleep at a regular time. However, lying in bed awake can lead to frustration and should be avoided. If sleep does not come within 20 minutes, it's recommended to get up and do something relaxing until feeling sleepy.
Choice B reason : Exercising can increase alertness and endorphin levels which can make it difficult to fall asleep if done too close to bedtime. Stopping exercise at least 2 hours before bedtime allows the body to wind down and prepare for sleep, making this statement correct and indicative of an understanding of good sleep hygiene practices.
Choice C reason : Watching television or engaging in other stimulating activities in the bedroom can associate the space with wakefulness rather than sleep. The light from screens can also suppress melatonin production, making it harder to fall asleep. Therefore, this statement does not reflect an understanding of the teaching on good sleep practices.
Choice D reason : Taking long naps, especially in the late afternoon or evening, can interfere with nighttime sleep. If naps are necessary, they should be limited to 20-30 minutes and taken earlier in the day. This statement suggests a misunderstanding of the impact of napping on sleep quality at night.
Correct Answer is D
Explanation
Choice A reason : Applying lotion between the toes is not recommended for individuals with diabetic neuropathy. Moisture can accumulate in these areas, creating an environment conducive to fungal infections. Instead, lotion should be applied to the tops and bottoms of the feet to keep the skin moisturized and prevent cracking, but the areas between the toes should be kept dry⁵.
Choice B reason : Wearing open-toed shoes is generally not advised for patients with diabetic neuropathy. Open-toed shoes can expose the feet to injuries, which can go unnoticed due to the loss of sensation associated with neuropathy. It's important for individuals with diabetic neuropathy to wear well-fitting, closed-toed shoes that protect the feet from external injuries⁵.
Choice C reason : Washing feet in hot water is unsafe for those with diabetic neuropathy because they may not be able to accurately gauge the temperature due to reduced sensation, leading to burns. The water temperature should be warm, and individuals should always test it with their hands or a thermometer before immersing their feet⁵.
Choice D reason : Walking barefoot is risky for individuals with diabetic neuropathy because they may not feel cuts, scrapes, or other injuries due to decreased sensation in their feet. These injuries can lead to infections and ulcers if not treated promptly. Therefore, it is crucial to avoid walking barefoot and to always wear protective footwear, even indoors⁵.
