What instruction should a nurse provide to an older adult client to encourage better nighttime sleep?

Encouraging better nighttime sleep for an older adult may involve specific strategies that promote relaxation and prepare the body for rest. Suggesting a light snack before bedtime is beneficial because it helps to create a sense of fullness without causing discomfort that a heavier meal might produce. Certain snacks, especially those containing carbohydrates, can facilitate the production of serotonin, a precursor to melatonin, which is the hormone that regulates sleep.

Eating a light snack can also prevent feelings of hunger that may otherwise disrupt sleep, promoting a more restful night. It's essential for older adults, who may have varying patterns of hunger and metabolism, to have a routine that supports both comfort and sleep hygiene as they prepare for bed. This approach can often alleviate problems associated with sleep disruptions, such as waking during the night due to hunger.

While the other options involve sound principles of health or activity, they may not directly support the goal of encouraging better sleep. For example, avoiding all liquids after 6 PM might lead to dehydration and discomfort if the client wakes up thirsty during the night. Vigorously exercising in the evening can increase energy levels and potentially make it harder to unwind before bedtime. Taking a longer nap in the afternoon could disrupt the natural nighttime sleep rhythm, making it more difficult to fall asleep
