A nurse is assisting with teaching a class about physiological changes that occur during sleep. The nurse should include that which of the following changes occur during non-rapid eye movement (NREM) sleep?

Choice A reason : Using a cane to ambulate is generally a measure to improve stability and reduce the risk of falling for individuals who may have balance or mobility issues. It is not inherently a risk factor for falls; rather, it is a compensatory strategy to mitigate the risk of falls1.
Choice B reason : Macular degeneration can significantly impact visual acuity and contrast sensitivity, leading to difficulties in navigation and increasing the risk of tripping or misjudging distances. Poor vision is a well-documented risk factor for falls, especially in unfamiliar or complex environments.
Choice C reason : A grab bar in the bathroom is a safety device installed to provide stability and support for individuals while they are using the bathroom facilities. It is a preventive measure against falls and does not increase the risk of falling.
Choice D reason : An electrical cord on the floor over a walkway is a tripping hazard. It is a common home hazard that can cause falls, especially in the elderly or those with mobility and visual impairments78.
Choice E reason : Unsecured throw rugs over tile floors are a recognized fall hazard. They can easily slip underfoot or cause tripping if the edges are not secured, which is particularly dangerous in areas like the kitchen where spills can make the floor even more slippery.

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.
