Final answer:
4.At least 6 hours before bedtimeThe nurse needs to investigate whether the client takes the medication at least 6 hours before bedtime to determine its impact on sleep.
Step-by-step explanation:
The nurse plans to investigate whether the client takes the medication at least 6 hours before bedtime.is a stimulant medication used to treat conditions such as ADHD and narcolepsy. Taking it too close to bedtime can interfere with sleep as it can cause increased alertness and difficulty falling asleep. By confirming that the client is taking the medication at least 6 hours before bedtime, the nurse can determine if the timing of the medication is causing the sleep problem.
If a client taking dextroamphetamine complains of difficulty sleeping, the nurse should plan to investigate when the client is taking their medication. Dextroamphetamine is a stimulant drug that can interfere with sleep, so it's important to take it at a time that is least likely to disrupt sleep. In this case, the nurse should check if the client is taking the medication at least 6 hours before bedtime to minimize the risk of sleep disturbance. This aligns with other sleep hygiene recommendations, such as avoiding stimulants before bed, to promote better sleep. Clinical guidance and the half-life of such stimulant medications generally suggest avoiding intake in the late afternoon and evening.
