NURS 262 SLEEP N REST WK 12 EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS
sleep
Altered state of consciousness in which the individual's perception of and reaction to the
environment are decreased
characteristics of sleep
Minimal physical activity
• Variable levels of consciousness
• Changes in the body's physiologic processes
• Decreased responsiveness to external stimuli
• Individuals may respond to meaningful stimuli, and selectively disregard non-
meaningful stimuli, i.e baby crying, smoke detector etc
WHY IS SLEEP IMPORTANT?
One of Maslow's physiological needs
• Restores physical and mental activity
• Needed for protein synthesis
• Affects mood, concentration and decision making
• Sleep disorders and deprivation adversely affect health and
adversely affect health and impair daily function
- physiologic well-being is best noticed by the deterioration in mental functioning related
to sleep loss
, • Individuals with inadequate amounts of sleep tend to become:•
Emotionally irritable
• Have poor concentration
• Experience difficulty making decisions
purpose of sleep
• Remains unclear
• Physiological and psychological restoration
• Maintenance of biological functions
dreams are
• Occur in NREM and REM sleep
• Important for learning, memory, and adaptation to stress
physiology of sleep
Sleep is an altered state of consciousness where perception of and reaction to
environment is decreased
-controlled by lower part of the brain
how is sleep controlled by lower part of the brain
Neurons in the reticular formation (brainstem) integrate sensory information from the
peripheral nervous system (PNS) and relay information to cerebral cortex
• The upper part of reticular formation, called the reticular activating system (RAS) is
involved with the sleep-wake cycle
what neurotransmitters are part of sleep
• Serotonin
• Gamma-aminobutyric acid (GABA)
