Q

What is Reflex Pain Response

A

A response of the central nervous system to pain

-rapid and automatic

-protective mechanism to prevent injury

-reflex depends on an intact, functioning neurologic reflex arc that involves both sensory and motor neurons

-e.g. touch something hot with your hand –> info sent to spinal cord via sensory neurons –> an interneuron sends message to motor neuron –> you remove your hand from the heat before your brain gets the message

Q

What is Inflammatory Response

A

A local response to injury or infection

-serves to localize and prevent the spread of infection and promote wound healing

Symptoms include: pain, swelling, heat, redness, and changes in function

Q

What is General Adaptation Syndrome (GAS)

A

Q

What happens during alarm reaction

A
  • Initiated when a person perceives a specific stressor and various defense mechanisms are activated

-Perception of threat may be conscious or unconscious

-The hypothalamic-pituitary-adrenal axis controls the neuroendocrine response
hormone and catecholamine levels rise to prepare body to react

Q

What is Phase 1 of the alarm reaction

A

Shock phase

Q

What happens during Stages of Resistance

A

Body now attempts to adapt to the stressor after having perceived the threat and mobilized its resources

Vital signs, hormone levels, and energy production return to normal

Body regains homeostasis if stress can be managed or confined to small area (LAS)

Adaptive mechanisms become exhausted if stressor is prolonged or strong enough to overwhelm the body’s ability to defend itself

Q

What happens during the Stage of Exhaustion

A

Results when the adaptive mechanisms can no longer provide defense

Depletion of resources that results in damage to the body in the form of wear and tear or systemic damage

Without defense against the stressor, the body may either:
- rest and mobilize its defenses to return to normal
- reach total exhaustion and die

Q

What are coping mechanisms

A

Behaviors used to decrease stress and anxiety

25
How do stressors vary
from person to person from one time to another in the same person by persons culture, family, genetic inheritance, and life experiences
26
What is a stressor
anything that is perceived as challenging, threatening, or demanding that triggers a stress reaction Can be physiologic or psychological
27
What is an Internal stressors
illness, hormonal change, fear
28
What is an External stressors
loud noise, cold temperatures
29
What are Physiologic Stressors
alteration of normal body structure and function
30
What are factors of physiologic stressors
Chemical agents (drugs, poisons) Physical agents (heat, cold, trauma) Infectious agents (viruses, bacteria) Nutritional imbalances Hypoxia Genetic or immune disorders
31
What are psychosocial stressors
Environment Interpersonal relationships Life events Accidents Stressful or traumatic experiences Horrors of history Current events of history Fear of aggression or mutilation Rapid changes in our world and the way we live
32
What is adaptation
the change that takes place as a result of the response to a stressor -ongoing process as a person strives to maintain balance in the internal and external environments necessary for: -normal growth and development -the ability to tolerate changing situations -the ability to respond to physical and emotional stressors
33
What are coping responses
Immediate response when a person is in a threatening or otherwise stressful situation
34
Describe Mind-Body Interaction
It is thought that humans react to threats of danger as if they were physiologic threats a person perceives a threat on an emotional level --> body prepares itself to either resist the danger or run away from it (fight or flight response)
35
What are Psychosomatic Disorders
physiologic alterations that are thought to be at least partially caused by psychological influences e.g. stress related diarrhea, nausea, heart palpitations, etc. -The number of changes a person has in life (both positive and negative) can be correlated with illness
36
What is fear
a feeling of dread in response to a known threat
37
What is anxiety
A vague, and easy feeling of discomfort or dread, the source of which is often unknown or nonspecific -most common human response to stress -feeling of apprehension caused by anticipating a perceived danger -A sign that alerts you to impeding danger and enables you to take measures to manage a threat
38
4 levels of anxiety
mild moderate severe panic
39
What is mild anxiety
-present in day-to-day living -increases alertness and perceptual fields (vision and hearing) -motivates learning and growth -facilitates problem solving -manifested by restlessness and increased questioning -may interfere with sleep
40
What is moderate anxiety
-narrows a person's perceptual field so focuses on immediate concerns -inattention to other communications and details -manifested by quavering voice, tremors, increased muscle tension, a complaint of "butterflies in the stomach", and slight increases in respirations and pulse
41
What is severe anxiety
creates a very narrow focus on specific details all behaviors to be geared toward getting relief impaired learning ability and easily distracted -characterized by extreme fear of a danger that is not real, by emotional distress that interferes with everyday life, and by avoiding situations that cause anxiety -manifested by difficulty communicating verbally, increased motor activity, a fearful facial expression , headache, nausea, dizziness, tachycardia, and hyperventilation anxiety is no longer functioning as a signal for danger or motivation for a needed change -instead results in maladaptive behaviors and emotional disability that signal presence of anxiety disorder
42
What is panic
-causes person to lose control and experience dread and terror -disorganized state characterized by increased physical activity, distorted perceptions of events, and loss of rational thought -person is unable to learn, concentrates only on the present situation, and often experiences feelings of impending doom -manifested by difficulty communicating verbally, agitation, trembling, poor motor control, sensory changes, sweating, tachycardia, hyperventilation, dyspnea, palpitations, a choking sensation, is sensation of chest pain or pressure -this level of anxiety can lead to exhaustion and death

What is situational stress
can occur at any time, although the person ability to adapt may be strongly influenced by his or her developmental level
49
Examples of situational stress
illness or traumatic injury marriage or divorce loss (of belongings, relationships, family members) new job role change
50
Stressors in nursingNursing
-assuming responsibilities for which you are not prepared working with unqualified personnel -working in an environment in which supervisors and administrators are not supportive -experiencing conflict with appear -caring for a patient who is suffering, and caring for the patient's family -caring for a patient during a cardiac arrest or for a patient who is dying -providing care to a patient who is disengaged, non adherent, or lacks the resources to participate in his or her care -moral distress -- knowing the correct, right, or ethical course of action in a situation, but being in able to take that action
51
What is Allostasis
describes the process of achieving stability or homeostasis through physiologic or behavioral change
52
Allostatic Load
the cumulative negative effects of these physical responses to prolonged environmental and psychosocial stressors
53
Burnout
becoming overwhelmed and developing symptoms of stress can be compared with the exhaustion phase of anxiety
54
Crisis
A disturbance caused by a precipitating event, such as a perceived loss, a threat of loss, or a challenge, that is perceived as a threat to self
55
Maturational Crisis
Occurred during developmental events that require role change e.g. when a teenager transitions into adulthood
56
Situational Crisis
Occur when a life event disrupts a person's psychological equilibrium e.g. job loss, death of a loved family member

58
Eustress

A biochemical model of stress that describes the body's general response to stress Physiologic response to stress but results from either physical or emotional stressors
61
Commonly occurring defense mechanisms:
Compensation Denial Displacement Dissociation Introjection Projection Rationalization Reaction formation Regression Repression Sublimation Undoing
62
Compensation
A person attempts to overcome a perceived weakness by emphasizing a more desirable trade or over achieving any more comfortable area Ex: a student who has difficulty with academics may excel in sports
63
Denial

69
Reaction formation

72
Sublimation
a person substitutes a socially acceptable role for one who's normal channel of expressionist blocked Ex: a person who is aggressive towards others may become a star football player
