Stress and Coping Flashcards
necessary changes that must occur to achieve the characteristic stability of homeostasis
allostasis
the body’s general, nonspecific response to the demands placed on it by the stressor. Not all stress is bad, some can help an individual achieve desired goals or exceed self-imposed limitations.
Stress
good stress associated with accomplishment and victory
eustress
stress that is associated with inadequacy, insecurity, and loss
distress
any event or stimulus that causes an individual to experience stress
stressor
dynamic process through which an individual applies cognitive and behavioral measures to handle internal and external demands that are perceived by the individual as exceeding their available resources
coping strategies/responses/mechanisms
Stress is defined as a stimulus, a life event, or a set of circumstances that arouses physiological and/or psychological reactions that may increase the individual’s vulnerability to illness.
Stimulus-Based Stress Models
the _____ of stressful life situations is used to document a person’s relatively recent experiences, such as divorce, pregnancy, and retirement. Both positive and negative events are considered stressful. Use cautiously, as each individual responds differently to different stressors.
Scale
the nonspecific response of the body to any kind of demand made upon it
Response Based Stress Model
can be observed only by the changes it produces in the body
Stress
by a chain or pattern of physiological events. this occurs with the release of certain adaptive hormones and subsequent changes in the structure and chemical composition of the body.
General Adaptation Syndrome
Parts of the body particularly affected by stress are the gastrointestinal tract, the adrenal glands, and lymphatic structures. Prolonged stress, deep ulcers appear in the lining of the stomach, the adrenal glands enlarge considerably, and the lymphatic structures (such as the thymus, spleen, and lymph nodes) atrophy.
Effect on the body
one organ or part of the body acts alone in response to stressors. An example; inflammation
Local adaptation syndrome
alerts the body’s defenses
Alarm Reaction
apart of the LAS and GAS stages: stress is perceived consciously or unconsciously by the person. Stressors stimulate the sympathetic nervous system, which stimulates the hypothalamus. This stimulates the release of corticotropin-releasing hormone, which will stimulate the anterior pituitary to release adrenocorticotropic hormone. This stimulates the adrenal medulla to secrete epinephrine and norepinephrine. the entirety of these responses allows the body to perform far more strenuous physical activity than otherwise possible. Lasts 1 minute to 24 hours.
Shock Phase / “fight or flight”
increased myocardial contractility (increases cardiac output and blood flow to active muscles). Bronchodilation (allows increased O2 intake), Increased blood clotting (in the event of traumatic blood loss), increased cellular metabolism, and increased fat mobilization (make available energy and synthesizes other components needed by the body.)
epinephrine response
decrease blood flow to the kidneys and increase secretion of rennin. the eventual result is an increase in blood pressure by constricting arterioles.
norepinehrine response
one of the LAS and GAS stages; the changes produced during the shock phase are reversed.
countershock phase
one of the LAS and GAS stages; when the body’s adaptation takes place. The body attempts to cope with the stressor and limit the stressor to the smallest area of the body that can deal with it.
resistance stage
one of the LAS and GAS stages; the adaptation made in stage two, cannot be maintained. However the body managed to cope with the stressor has now been exhausted. If the stressor has not been eliminated prior to this stage, it may begin to spread to the entire body. the body must either rest and return to normal or die. the length of this stage and its eventual end are dependent on adaptive energy resources, the severity of the stressor, and the external adaptive resources (Oxygen).
exhausation stage
any factor that produces stress and disturbs the body’ equilibrium
stressor
can be observed only by the changes it produces in the body
stress
A set of cognitive, affective, and adaptive (coping) responses that arise out of person-environment transactions. The person and environment are inseparable, each affects and is affected by the other. The nurse must consider the person as an community, culture and environment.
Transaction - Based Stress Models
The relationship between the nurse, the client, and the environment in which they interact. The emphasis is on the relationship among stress, the client, the nurse, and both the internal and external environment. This model emphasizes interpersonal relationship with the client with the intent of decreasing the client’s anxiety and increased or improving the client’s coping resources.
