π- Stress, Nutrition, Fluid & Electrolyte Test Flashcards
Distress vs eustress
Distress- threatens health
Eustress- βgood stressβ is protective
External vs internal
External stressor- stressors may be external to the person ex: death of a family member
Internal- ex: disease, anxiety or nervous anticipation of an event
Developmental stressors vs situational stressors
Developmental- those that can be predicted to occur at various stages of a persons life
Situational- unpredictable , ex: you canβt predict if you will experience a car accident
Physiological stressor vs psychosocial stressor
Physiological- those that affect body structure or function
Psychosocial - are external stressors that arose from work, family dynamics, living situation, social relationships and other aspects of our daily lives
Adaptive (effective) coping
Consists of making healthy choices that reduce the negative effects of stress
Ex: exercising to relieve tension , etc
Maladaptive (ineffective) coping
Does not promote adaption
General adaptation syndrome
Selyeβs name for the group of nonspecific responses that all people share in the face of stressors
What are the 3 stages of GAS
- Alarm stage
- Resistance (adaptation)
- Final stage either recovery or exhaustion
What are the two phases of the alarm stage
Shock - begins when the cerebral cortex first perceives a stressor and sends out messages to activate the endocrine and sympathetic nervous systems
Countershock - all the changes produced in the shock phase are reversed , person becomes less able to deal with the immediate threat
Resistance stage
The body tries to cope, protect itself against the stressor and maintain homeostasis through the use of physiological and psychological coping mechanisms
Reflex pain response
Protective reflex to pain
Ex: moving hand from a hot stove
Inflammatory response
Local reaction to cell injury
List 4 emotional responses to stress
Anxiety
Fear
Anger
Depression
Conversion
Ego defense mechanism
Emotional conflict is changed into physical symptoms that have no physical basis. The symptoms often disappear after the threat is over
Ex: developing nausea that causes the person to miss a major exam
What 3 types of disorders can develop when adaptation fails
- stress induced organic responses
- somatoform disorders
- stress induced psychological responses
Stress-induced organic responses
Continual stress brings about long-term changes in various body systems
Ex: overeating, substance abuse
Somatoform disorders
Conditions characterized by the presence of physical symptoms with no known organic cause
Ex: hypochondriasis, somatization, pain disorder, malingering
Somatization
Anxiety and emotional turmoil are expressed in physical symptoms, loss of physical function, pain that changes location often and depression
Unable to control the symptoms and behaviors, and complaints are vague or exaggerated
Pain disorder
Emotional pain that manifests physically
Level of pain the person states is inconsistent with the physical condition- the pain doesnβt change location
Malingering
Conscious effort to escape unpleasant situations
Patient pretends to have the symptoms for personal or tangible gain
Ex: calling in sick because the person doesnβt want to go to work
Stress-induced psychological responses
Long-term stress leads to exhaustion and mechanisms begin to fail.
Person may try maladaptive wAys to cope
Ex: crisis, burnout, ptsd
Carbohydrates CHO
The primary energy source for the body
- increase satiety
- spare proteins
- enhance insulin secretion
- improve absorption of Na and excretion of Ca
Nitrogen balance
Occurs when intake and output of nitrogen are equal
Positive - nitrogen intake exceeds output , making a pool of amino acids available for growth , pregnancy , tissue maintenance and repair
Negative- intake lower than loss. Occurs in illness, injury (burns) and malnutrition
Proteins
Secondary energy source
- fluid balance (attract water)
- immune system function
- acid/base balance
