The nurse has been teaching a patient ways to improve sleep patterns at home. The nurse determines that teaching has been effective when the patient states which of the following?
A) "There isn't enough caffeine in most drinks to really affect sleep."
B) "I quit smoking a few days ago so I should be sleeping better already."
C) "A glass of wine before bed should help me sleep all through the night."
D) "I need to take cold medicine that contains caffeine no later than midafternoon."
Ans: D
Feedback:
Caffeine is a stimulant that results in delayed sleep onset, decreased total sleep time, increased wake after sleep onset, and decreased rapid eye movement (REM) and slow–wave sleep. Caffeine is also found in over-the-counter cold preparations and stimulants. Although people differ in the intensity and duration of their response to caffeine-containing products, the effects of such products may last as long as 8 to 14 hours. Nicotine also has a powerful influence on sleep, producing more arousal with higher doses. Withdrawal from nicotine can result in irritability and inadequate sleep. Many people use alcohol to self-treat insomnia. Although its acute sedative effects may lead to drowsiness and shorten sleep latency, its longer-term effects include arousal and wakefulness.
