Define
homeostasis
Equilibrium, balance
between physiological,
psychological, sociocultural,
intellectual and spiritual
needs
Explain how the
autonomic nervous system
regulates homeostasis
Sympathetic: increases HR, BP,
rapid shallow respirations
diaphoresis, increase blood
glucose production, excess
gastric acid, slowed digestion,
increased metabolism, pupils
dilate
Parasympathetic: maintenance
of normal, smooth functioning
exerts opposite effects of
sympathetic ANS
Define adaptation
an ongoing process by which
individuals adjust to
stressors in order to achieve
homeostasis
Explain how the
endocrine system
regulates homeostasis
Epinephrine: CV
Respiratory
CV: constricts blood vessels,
dilates muscle, brain,
coronary vessels, elev BP,
increased cardiac output
RESP: increases rate/depth
of respirations, dilates
bronchi
Explain how the
endocrine system
regulates homeostasis
Epinephrine: Nervous syst
Metabolism
NS: stimulates CNS increasing
alertness, feeling of fright,
excitations an dimpending doom, dilates pupils,inhibits
GI tract
Metabolism: increases the
nonsterified fatty acid level
of blood, promotes conversion
of glycogen to glucose
increases body metabolism
Explain how the
endocrine system
regulates homeostasis
Norephinephrine: CV
CV: constricts all blood vessels especially
peripherally markedly
hypertensive decreases cardiac
output because of increases
peripheral resistance
increases pulse, not greatly
Explain how the
endocrine system
regulates homeostasis
Norephinephrine: NS
Metabolism
NS: dilates pupils
inhibits the gi tract
Metabolism: increases the
nonsterified fatty acid level
of blood, increases body
metabolism slightly
Describe how the
respiratory system
interacts to maintain
homeostasis
controls the amt. of O2 in
cellular fluid and in plasma of
blood.
Describe how the
cardiovascular system
interacts to maintain
homeostasis
increases cardiac output
regulates blood pressure
heart rate
constriction/dilation of
vessels
Describe how the
renal system
interacts to maintain
homeostasis
filters out harmful wastes
from the flood and regulates
fluid output.
Describe how the
gastrointestinal system
interacts to maintain
homeostasis
regulates fluid output
and fluid absorption affecting
homeostasis
Identify Selye's
definition of stress
a non-specific demand which
requires an individual to
respond or take action
Describe the 3 stages
of Selye's general
adaptation syndrome (GAS)
Alarm rxn:
Alarm rxn: involves mobilization
of the defense mechanisms of
the body and mind to cope with
the stressor. Fight or flight
response. pt anxious, nausea,
decreased appetite, GI tract
slows
Resistance stage:
Resistance stage: the body
stabalizes and hormone levels,
HR, BP, cardiac output return to normal. Recovery. Person
can be said to be adapting to
stressors body repairs
damage - stabalizes. Can move
directly to recovery stage.
Exhaustion stage:
Exhaustion stage: the body can
no longer resist stress and
energy is depleted - die.
Identify physiologic
manifestations of stress
CV/Resp effects - increased
pulse, bp, rapid breaths
Neuro-dizzy, HA, dilated pupils
GI - n/d, altered appetite,
constipation
GU-polyuria
MS - tension, twitching
Endocrine - increased levels
of blood glucose and cortisol
Identify psychological
manifestations of stress
Cognitive - impaired memory
confusion, impaired judgement,
poor decision-making
delayed response time
altered perceptions, inability
to concentrate
Behavioral: pacing, sweaty,
rapid speech, insomnia, w/d
Spiritual: alienation, social
isolation, emptiness feeling
Describe coping
behaviors evidenced by
a client experiencing
stress
compensation
denial
displacement
disassociation
When patients use
relaxation techniques
what 5 changes would
you expect to happen?
decreased HR
decreased RR
decreased blood sugar
decreased BP
increased urine output
What are some
relaxation techniques?
stimulate parasympathetic
response
touch
focus on deep breathing
imagery/visualization
distraction
