1F Flashcards
A body’s physiological reaction to any stimulus that evokes changes
stress
Universal experience that can be a catalyst for a positive change or it can be the source of discomfort and pain
stress
A stimulus that evokes the need to adapt
STRESSOR
a state when stressors evoke an ineffective response
DISTRESS
results in positive outcome
EUSTRESS
An ongoing process by which individuals adjust to stressors in order to achieve homeostasis
ADAPTATION
Describes as a holistic response which involves all dimensions of an individual physiological, psychological, cognitive, social and spiritual
ADAPTATION
Transmission of evaluative or corrective information on stress
FEEDBACK
It refers to how individuals respond and react to a given stressful situation or event
FEEDBACK
An unconscious operations that protect the mind from anxiety
DEFENSE MECHANISM
Body’s self-regulation of physiological process
HOMEOSTASIS
State of rest and balance
EQUILIBRIUM
SOURCES OF STRESS
INTERNAL STRESSORS
EXTERNAL STRESSORS
DEVELOPMENTAL STRESSOR
SITUATIONAL STRESSORS
source of stress that originate within an individual
INTERNAL STRESSORS
source of stress that Originate outside the individual
EXTERNAL STRESSORS
source of stress that Occurs at predictable times throughout an individual’s life
DEVELOPMENTAL STRESSOR
source of stress that are unpredictable and may occur at any time during life. It may be positive or negative
SITUATIONAL STRESSORS
EFFECTS OF STRESS
PHYSICALLY
EMOTIONALLY
INTELLECTUALLY
SOCIALLY
SPIRITUALLY
Three main models of stress
Stimulus-based models
Response-based models
Transaction-based models
Stress is defined as: stimulus, life event, or a set of circumstances that arouses physiologic and psychologic reactions that may increase the individual’s vulnerability to illness
STIMULUS-BASED MODELS
Characterized by a chain or pattern of physiologic events called the general adaptation syndrome (GAS) or stress syndrome
RESPONSE-BASED MODELS
common stressors
Physiological
Psychological
Cognitive
Environmental
Sociocultural
THREE (3) STAGES OF GAS
ALARM
RESISTANCE
EXHAUSTION
stage of GAS: When stimulus occurs, it signals to hypothalamus to release glucocorticoids (sugar) which release adrenaline and cortisol ( focuses on the production of energy ) which increases energy
ALARM
stage of GAS: The body attempts to cope with the stressor and to limit the stressor to the smallest area of the body that can deal with it
RESISTANCE
stage of GAS: In this stage, it will stimulate the parasympathetic branch wherein the parasympathetic branch will try to normalize through decreasing certain levels to attain homeostasis
RESISTANCE
stage of GAS: The body’s adaptation takes place.
RESISTANCE
stage of GAS: End of this stage, the body may either rest and return to normal, or death may be ultimate consequence
EXHAUSTION
stage of GAS: There is a depletion of energy - The difficult thing about not moving towards exhaustion stage if the stimulus is prolonged, it will have difficulty decreasing it to normality.
EXHAUSTION
The body can also react locally; that is, one organ
or a part of the body reacts alone
LOCAL ADAPTATION SYNDROME (LAS)
the physiological response to a stressor (e.g., trauma, illness) affecting a specific part of the body.
LOCAL ADAPTATION SYNDROME (LAS)
Manifestations of Stress
Physiological
psychological
Cognitive
Behavior
Spiritual
Views stressor as an individual response needed in psychological and cognitive process
TRANSACTION-BASED MODELS
CONCEPT OF STRESS ADAPTATION (theoretical methods)
BETTY NEUMAN’S SYSTEM MODEL
RESPONSE-BASED MODEL OF STRESS
ADAPTATION MODEL
STIMULUS-BASED MODEL OF STRESS
TRANSACTIONAL MODEL OF STRESS
A nursing theory based on the individual’s relationship to stress, the reaction to it, and reconstitution factors that are dynamic in nature
BETTY NEUMAN’S SYSTEM MODEL
Describes the system model as a unique open system based perspective that provides a unifying focus for approaching a wide range of concerns.
BETTY NEUMAN’S SYSTEM MODEL
Based on the physiologic manifestation; flight and fright, controlled by the nervous system and endocrine system
RESPONSE-BASED MODEL OF STRESS
