A nurse is reinforcing teaching with a client who is scheduled to have a colonoscopy in 1 week. Which of the following client statements indicates an understanding of the teaching?

Rationale:

A. Put a simple lock on the client's bedroom door: Locking the client's door could pose a safety risk, especially in the event of an emergency such as a fire. It also restricts the client's autonomy and may increase confusion or agitation in clients with Alzheimer's disease.

B. Give the client a barbiturate medication at bedtime: Barbiturates are not recommended for older adults due to their sedating effects and risk of dependence, falls, and worsening cognitive function. Non-pharmacologic strategies are preferred first in managing sleep disturbances.

C. Encourage the client to take frequent walks during the day: Physical activity during the day helps reduce nighttime restlessness and improve sleep patterns. Walking can also help regulate circadian rhythms, promote relaxation, and reduce wandering behavior at night.

D. Allow the client to nap for at least 1 hr during the day: Long daytime naps may disrupt the sleep-wake cycle, worsening insomnia and nighttime wandering. Limiting daytime napping and encouraging activity is more effective in promoting restful nighttime sleep.

Rationale:

A. Preeclampsia: Methylergonovine causes vasoconstriction and increases blood pressure, which can be dangerous in clients with preeclampsia. Administering this medication in such cases can elevate the risk of stroke or seizure due to worsening hypertension.

B. An allergy to penicillin: Methylergonovine is not a penicillin-based medication, so a penicillin allergy does not present a known contraindication or concern. Caution is unnecessary unless there is a known allergy to ergot alkaloids.

C. Gestational diabetes mellitus: Methylergonovine does not significantly impact blood glucose levels or insulin sensitivity. Therefore, it can be used safely in clients with gestational diabetes when indicated for hemorrhage control.

D. Cholelithiasis: There is no direct interaction or exacerbation of gallbladder disease with methylergonovine. The medication primarily acts on uterine smooth muscle and vascular tone, not on the biliary system.
