The nurse is educating a patient about taking measures to help avoid disruption to the circadian rhythm. The following 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.

Question 2

The nurse knows that polysomnograpy is:
 
  a. the recording of brain waves and other variables.
  b. the relay of motor impulse to the hypothalamus.
  c. the patterns of biological functioning.
  d. the recording of seizure activity in the brain.

Answer to Question 1

ANS: B
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.

Answer to Question 2

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 electroencephalogra m is used to record seizure activity in the brain.
