Sleep Hygiene Teaching for Insomnia
Physiologic Needs · Question from the ATI PN Fundamentals 2023 Proctored Exam study set
Correct answer: "I should stop drinking caffeine two hours before bedtime."
Why this is the answer
Limiting caffeine intake before bedtime reduces its central nervous system stimulant effect, which can otherwise delay sleep onset and fragment sleep.
The bigger concept
Sleep hygiene teaching centers on removing stimulants and building a consistent routine: same bedtime and wake time, no caffeine or nicotine for several hours before bed, no alcohol as a sleep aid, no screens in bed, a cool dark room, and getting up if not asleep within 20 minutes. Exercise helps sleep but should be finished a few hours before bedtime. The PN/VN reinforces these before medications are considered.
