The nurse is caring for a client prescribed zolpidem, a hypnotic CNS depressant. At what time should the nurse plan to administer this medication to maximize its sleep-inducing effectiveness?

• A. Immediately before bedtime
• B. 15-30 minutes before bedtime
• C. 60-90 minutes before bedtime
• D. 30-60 minutes before bedtime

Answer: (D)

Timing the administration of zolpidem to align with when you plan to sleep is essential because this hypnotic needs a short lead time to begin working. Zolpidem typically starts to act within about 15 to 30 minutes after ingestion, with its peak effect as you settle into sleep. Planning to take it about 30 to 60 minutes before bedtime gives it enough time to be absorbed and start helping you fall asleep as you lie down, while also minimizing the chance of lingering daytime drowsiness. If you take it immediately before bed, there may not be enough time for it to take full effect as you’re trying to sleep. If you take it 60–90 minutes before bed, the peak effect could occur well before you fall asleep, which might reduce its usefulness and potentially lead to morning sedation. The 30–60 minute window best balances onset with the actual sleep initiation, maximizing the sleep-inducing effect.
