Test 2 Flashcards
Define teaching
the concept of imparting knowledge through a series of directed activities. (It consists of a conscious, deliberate set of actions that help individuals gain new knowledge, change attitudes, adopt new behaviors, or perform new skills.)
Define learning
the purposeful acquisition of new knowledge, attitudes, behaviors, and skills through an experience or external stimulus.
What are the three major purposes of comprehensive patient education?
- health promotion and illness prevention
- health restoration
- coping
What is the goal of education others about their health?
to help individuals, families, or communities achieve optimal levels of health.
What are the three domains of learning?
- Cognitive (understanding)
- Affective (feelings, attitudes, beliefs)
- psychomotor (motor skills)
What are the six cognitive behaviors that make up cognitive learning?
- Remembering (learning new info)
- Understanding (knowing the meaning of the new info)
- Applying (using the info/idea in a new situation)
- Analyzing (breaking down and organizing the info)
- Evaluation (ability to judge the value of something for a given purpose)
- Creating (ability to apply knowledge and skills to create something new)
What are the five behaviors associated with affective learning?
- Receiving (learner is passive; involves only paying attention to the information being presented)
- Responding (active participation; listing and then reacting verbally and nonverbally)
- Valuing (attaching worth and value to the acquired info as demonstrated by the learner’s behavior)
- Organizing (developing a value system and organizing values according to their worth)
- Characterizing (acting and responding with a consistent value system; requires introspection and self-examination of one’s own values
WHAT IS THE CIRCADIAN RHYTHM?
24 HOUR DAY-NIGHT CYCLE/SLEEP CYCLE (aka diurnal)
What controls the rhythm of the sleep-wake cycle and coordinates it with other circadian rhythms?
the suprachiasmatic nucleus (SCN) nerve cells in the hypothalamus
What major biological and behavioral functions have their patterns influenced by circadian rhythms?
body temperature heart rate blood pressure hormone secretion sensory acuity mood
What factors affect circadian rhythms and daily sleep-wake cycles?
light
temperature
social activities
work routines
What does RAS stand for and what does it do?
Reticular activating system (in the hypothalamus):
it maintains alertness, wakefulness, and consciousness by releasing catecholamines such as norepinephrine in response to visual, auditory, pain, and tactile sensory stimuli, as well as responds to activity from the cerebral cortex such as emotions or thought process.
What does the homeostatic process do?
primarily regulates the length and depth of sleep (aka process S)
What do the circadian rhythms influence?
the internal organization of sleep and the timing and duration of sleep-wake cycles (aka Process C: biological time clocks)
What is time of wake up defined by?
the intersection of process s and process c
What is the major sleep center in the body and what does it secrete? for what purpose?
the hypothalamus secretes hypocretins (orexin) that promote wakefulness and rapid eye movement (REM) sleep.
Prostaglandin D2, L-tryptophan, and growth factors control sleep.
What are the two phases of normal sleep?
non rapid eye movement (NREM)
rapid eye movement (REM)
What does each sleep cycle consist of and how long is it?
Each cycle consists of four stages of NREM sleep and a period of REM sleep and is approx 90-100 minutes long.
How many sleep cycles does a person usually pass through per night?
4-5, depending on the total amount of time a person spends sleeping
When does a person usually reach REM sleep?
about 90 minutes into the sleep cycle
What happens during stage 1 of NREM sleep and how long does it last?
Last a few minutes
Light sleep with decreased physiological activity begins with gradual fall in vital signs and metabolism. (easy arousal)
What happens during stage 2 of NREM sleep and how long does it last?
Lasts 10-20 min
Sound sleep where relaxation progresses and body functions continue to slow. (easy arousal)
What happens during stage 3 of NREM sleep and how long does it last?
Lasts 15-20 min
Initial stages of deep sleep where muscles are completely relaxed, vital signs decline but remain regular. (arousal is difficult and sleeper rarely moves)
WHAT HAPPENS DURING STAGE 4 OF NREM SLEEP AND HOW LONG DOES IT GENERALLY LAST?
Lasts approx 15-30 min
Deepest stage of sleep where vital signs are significantly lower than during waking hours; SLEEP PARALYSIS (AROUSAL IS VERY DIFFICULT)
