A nurse is creating a plan of care for a client who reports difficulty sleeping. Which of the following interventions should the nurse include?

Rationale: A. Warm milk is a nonpharmacologic sleep aid that may promote relaxation and sleep. It contains tryptophan, an amino acid that supports the production of serotonin and melatonin, which help regulate sleep cycles. Establishing a calming bedtime routine is also a key component of improving sleep hygiene. B. While daytime or early evening activity can promote better sleep, ambulating immediately before bedtime may stimulate the client, increase alertness, and make it harder to fall asleep. C. Sleep hygiene is improved by consistent routines, not variation. A predictable bedtime routine helps regulate the body’s circadian rhythm and signals to the body that it is time to sleep. D. Frequent nighttime interruptions can disrupt sleep cycles and reduce sleep quality. Nursing care should be clustered whenever possible to promote uninterrupted rest and recovery.
