A nurse is teaching a client about prescribed zolpidem. Which client statement should the nurse identify as requiring follow-up education before administering the medication?

A. "I will eat a light snack in the evening to avoid taking zolpidem on an empty stomach": Zolpidem is absorbed more rapidly when taken on an empty stomach, which promotes quicker onset of action. Taking it with food, especially a heavy meal, can delay absorption and reduce its effectiveness for sleep initiation. B. "I will avoid caffeine in the afternoon to help me sleep better": Caffeine is a central nervous system stimulant that antagonizes adenosine receptors and promotes wakefulness. Avoiding caffeine later in the day supports sleep hygiene and enhances the effectiveness of sedative-hypnotic medications like zolpidem. C. "I will drink a glass of warm milk before bed to help me relax": Warm milk may promote relaxation as part of a bedtime routine and supports good sleep hygiene practices. Establishing consistent pre-sleep rituals can enhance the hypnotic effects of zolpidem. There is no significant interaction between milk and zolpidem that would reduce safety. D. "I will drink grapefruit juice with dinner every night”: Grapefruit juice inhibits intestinal cytochrome P450 3A4 enzymes, which are involved in the metabolism of zolpidem. Inhibition of this pathway can increase serum drug concentrations and prolong sedation. Elevated levels raise the risk of excessive drowsiness, impaired cognition, and complex sleep-related behaviors.
