A nurse is teaching a newly licensed nurse about physiological changes in the digestive system that occur with aging.The nurse should include older adults might experience which of the following physiological changes?

Choice A rationale

Hypothermia is not commonly associated with diarrhea. Diarrhea typically leads to fluid loss and dehydration rather than changes in body temperature.

Choice B rationale

A rigid abdomen is not a typical finding for diarrhea. It may indicate other gastrointestinal issues, such as peritonitis, rather than dehydration caused by diarrhea.

Choice C rationale

Decreased bowel sounds are not typically expected with diarrhea, which often presents with increased bowel sounds due to increased motility.

Choice D rationale

Dehydration is a common finding in clients with diarrhea due to the excessive loss of fluids and electrolytes from frequent, loose stools. It can lead to symptoms such as dry mouth, reduced urine output, and dizziness.

Choice A rationale

Instilling ophthalmic medication directly on the cornea can cause irritation and discomfort. Medications should be administered in the conjunctival sac.

Choice B rationale

Asking the client to tightly squeeze their eyes shut after instillation can expel the medication, reducing its effectiveness. Gentle closing of the eyes is recommended.

Choice C rationale

Cleaning the eye from the outer canthus to the inner canthus is not the proper method. The correct method is to clean from the inner canthus to the outer canthus to avoid contaminating the inner eye.

Choice D rationale

Applying pressure to the nasolacrimal duct after instillation helps prevent the medication from draining into the nasolacrimal system, ensuring better absorption in the eye. .
