MULTIPLE CHOICE
1. The nurse identifies what physiological response occurs with the onset of darkness and in
preparation for sleep?
a. Cortisol levels peak
b. Cortisol levels increase
c. Core body temperature increases
d. Melatonin levels increase
ANS: D
Melatonin levels increase and core temperature and cortisol levels decrease with the onset of
darkness. Cortisol levels peak at 6 a.m.

2. The nurse recognizes what function of the reticular activating system (RAS)?
a. Records brain waves and other variables.
b. Relays motor impulse to the hypothalamus.
c. Influences patterns of biological functioning.
d. Is affected by the light-dark cycle. G B.C M
N R I
ANS: B
U S N T O
The RAS receives sensory impulses from the spinal cord and relays motor impulses to the
thalamus and all parts of the cerebral cortex. Polysomnography is the recording of brain
waves and other physiologic variables, such as muscle activity and eye movements, during
sleep. The circadian rhythms influence patterns of biological and behavioral functions, and the
sleep-wake circadian rhythm is affected by the light-dark cycle.

3. The nurse is educating a patient about taking measures to help avoid disruption to the
circadian rhythm. Which statement by the patient indicates a need for further education?
a. ―I know the circadian rhythm influences biological functions.‖
b. ―I know the circadian rhythm exists only in humans.‖
c. ―I know the sleep-wake circadian rhythm is impacted by the light-dark cycle.‖
d. ―The most familiar circadian rhythm is the day-night 24-hour cycle.‖
ANS: B
, DAWIT
Biological rhythms exist in plants, animals, and humans. In humans, these biorhythms, along
with internal and external factors, affect sleep. The most familiar rhythm is the day-night,
24-hour circadian rhythm cycle. Circadian rhythms influence patterns of biological and
behavioral functions. Some creatures are diurnal, or primarily active during the day, whereas
others are nocturnal, with most of their activity during the night.

4. The nurse teaches the patient what information about polysomnograpy?
a. This is the recording of brain waves and other variables.
b. This is the relay of motor impulse to the hypothalamus.
c. This is the patterns of biological functioning.
d. This is the recording of seizure activity in the brain.
ANS: A
Polysomnography is the recording of brain waves and other physiologic variables, such as
muscle activity and eye movements, during sleep. The reticular activating system (RAS)
receives sensory impulses from the spinal cord and relays motor impulses to the thalamus.
The circadian rhythms influence patterns of biological and behavioral functions. An
electroencephalogram is used to record seizure activity in the brain.

5. The nurse identifies which seN
quUeR
ncSeItoNbGeTthBe.
uC alMprogression of sleep?
suO
a. NREM 1-3 then REM, then back through NREM 1 and 2
b. REM then NREM 1-4, then back through NREM 2 and 3
c. NREM 1-3 then back through NREM 3 and 2 then REM
d. REM then NREM 1-4 then back through NREM 3
ANS: C
The usual sleep sequence for a person is a fairly rapid progression through NREM 1 through
3, back through NREM 3 and 2, and then into REM sleep. There is no NREM stage 4.

6. The nurse is providing discharge instructions to the parents of a toddler about sleeping habits.
Which statement indicates further education is needed?
a.―Sleep needs may change during growth spurts.‖
b.―Children sleep 12 hours a day.‖
c.―Toddlers will often resist going to bed.‖
d.―The bedtime routine can vary.‖
ANS: D
The regular bedtime routine should be consistently followed. Children need 11 to 14 hours of
sleep a day, and toddlers and preschoolers may exhibit resistance to going to bed. Sleep needs
fluctuate with growth spurts.
