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 |
