exam 1 (chapters 1,2,3,4,5,6,7,12) Flashcards
1
Q
stress
A
an individual’s reaction to any change that requires an adjustment or response
- can be physical, mental or emotional
2
Q
healthy adaptions
A
responses directed at stabilizing internal biological processes and psychological preservation of self-identity
3
Q
adaptive
A
behavior that maintains the integrity of the individual (positive)
4
Q
maladaptive
A
behavior disrupts the integrity of the individual (negative)
5
Q
stressor
A
a biological, psychosocial, social, or chemical factor that causes emotional or physical tension
6
Q
general adaptation syndrome
A
“fight or flight”, Hans Selye; 3 stages
1. alarm reaction- fight or flight
2. resistance- uses physiological responses of first stage as a defense in attempt to adapt to the stressor
3. exhaustion- body responds to prolonged exposure to a stressor, adaptive energy is depleted, diseases of adaption may occur
7
Q
stress as a biological response: hypothalamus stimulates SNS which innervates
A
adrenal medulla- norepinephrine and epinephrine is released
eye- pupils dilate
respiratory- bronchioles dilate and rr increases
cardiac- increase force of cardiac contraction, cardiac output, heart rate, and BP
GI- decrease motility and secretions sphincters contract
liver- increased glycogenesis and gluconeogenesis, decreased glycogen synthesis
urinary- decreased ureter motility, bladder muscle contracts sphincter relaxes
sweat- increased secretions
fat cells- lipolysis
8
Q
stress as an environmental event: hypothalamus stimulates pituitary gland which releases:
A
ACTH- stimulates adrenal cortex which releases glucocorticoids (increases glucogenesis, decreases immune response and inflammatory response) and mineralocorticoids (increases retention of Na and H2O)
vasopressin (ADH)- increases BP through constriction of blood vessels and increases fluid retention
growth hormone- direct effect on protein, carbs, and lipid metabolism, resulting in increase of serum glucose and free fatty acids
thyrotropic hormone (TSH)- stimulates thyroid gland which increases basal metabolic rate
- increased levels of thyroid hormones (decreased secretion of TSH) leads to insomnia, anxiety, emotional lability)
- decreased levels of thyroid hormones (increased secretion of TSH) leads to fatigue and depression
gonadotropins- initially increases sex hormones and later with sustained stress will decrease secretion of sex hormones which leads to decrease libido impotence
9
Q
stress as an environmental event
A
defines stress as an EVENT (which creates change in the life pattern of the individual requires significant adjustment) that triggers adaptive physiological and psychological responses
10
Q
stress measured with RLCQ
A
high score = greater susceptibility to physical/psychological illness
criticized bc doesn’t consider individual ability to cope
11
Q
stress as a transaction
A
transaction between the individual and the environment, emphasizes relationship between internal and external variables
12
Q
stress as a transaction
A
precipitating event leads to cognitive appraisal leads to primary response:
irrelevant- no response
benign positive- pleasurable response
stress appraisals: harm/loss, threat, or challenge (lead to secondary response)
consider availability of coping strategies, perceived effectiveness of coping strategies, and perceived ability to use coping strategies effectively
leads to quality of response, either adaptive or maladaptive
13
Q
precipitating event
A
stimulus arising from internal or external environment perceived by the individual in a specific manner
14
Q
cognitive appraisal
A
individuals evaluation of personal significance of the event
15
Q
predisposing factors
A
genetic influences, past experiences, existing conditions
16
Q
hobfoll’s conservation of resources theory
A
as existing conditions exceed the person’s perception of adaptive capabilities the individual not only experiences stress in the present but also becomes more vulnerable to the effects of stress in the future

CNS: the brain
interprets info from the sensory receptors (PNS), effects a response, structurally has 2 hemispheres and 3 divisions: forebrain, midbrain, and hindbrain
35
forebrain
cerebrum and diencephalon
36
cerebrum
outer layer = cerebral cortex
largest part of the brain, interprets info received from the midbrain and decides what happens next, each hemisphere contains frontal, parietal, temporal and occipital lobes
37
frontal lobes
controls voluntary body movement, executive functions such as THINKING, JUDGEMENT, AND EXPRESSION OF FEELINGS
38
parietal lobes
its primary function is associated with LANGUAGE RECOGNITION; interprets sensory info like touch, pain, and taste
39
temporal lobes
manages HEARING, SHORT TERM MEMORY, and sense of smell
**schizo patients**
40
occipital lobes
focal center for visual reception and interpretation
41
diencephalon
the relay center for most sensory input from the PNS, direct autonomic, endocrine and motor function control, effects homeostasis, hearing, vision, taste, and touch perception
thalamus, hypothalamus, and limbic system
42
thalamus
integrates all sensory input except smell prior to being sent to the cortex
43
hypothalamus
regulates anterior and posterior pituitary gland, CONTROLS AUTONOMIC NERVOUS SYSTEM (ANS is part of PNS), manages APPETITE and body temp, BP, thirst
44
limbic system
THE EMOTIONAL BRAIN

monoamines
modulate wide range of moods (depression, mania, anxiety) as well as thought disorders such as schizophrenia
**NOREPINEPHRINE, DOPAMINE, SERATONIN, AND HISTAMINE**
dopamine: frontal cortex/limbic system, decreased levels can lead to depression, increased levels (prolactin) lead to mania and schizo
serotonin: decreased levels = depression
histamine: functions include wakefulness
62
amino acids
make neuron's dendritic receptor sites either less likely to "fire" (inhibitory) or increase fire likelihood (excitatory)

116
crisis
a sudden event in one's life that disturbs homeostasis during which the usual coping mechanisms cannot resolve the problem
117
characteristics of a crisis
crisis occurs in all individuals at one time or another and is not necessarily equated with psychopathology
precipitated by specific, identifiable events, personal by nature, acute (usually resolving in 1-3 months) and not chronic
118
phases in development of a crisis
1: individual is exposed to a precipitating stressor
2: when previous problem-solving techniques do not relieve the stressor, anxiety increases further
3: all possible resources are called on to resolve the problem and relieve the discomfort
4: if resolution does not occur in previous phases, the tension mounts beyond a further threshold or its burden increases to a breaking point
119
3 balancing factors
the individual's perception of the event
the availability of situational support
the availability of adequate coping mechanisms
120
ATI types of crisis
situational (loss/change experienced everyday: divorce, job change)
maturational (developmental stages: marriage, baby, empty nest, retirement)
adventitious (natural disasters, crimes, community trauma)
121
crisis intervention
the goal is to at minimum restore individual to previous functioning level and possibly to higher level by enhancing personal growth
122
phases of crisis intervention (role of the nurse)
1. assessment
2. planning of therapeutic intervention
3. intervention
4. evaluation of crisis resolution and anticipatory planning
123
disaster
a common feature of disasters is that they overwhelm local resources and threaten the function and safety of the community
leave victims with a damaged sense of safety and well-being and varying amounts of emotional trauma
124
psychotropic medications
"mind-altering", they do not cure
medications work best with therapy and life style changes
125
neurotransmitter (pharm)
a chemical that is stored in the axon terminals of the presynaptic neuron
an electrical impulse through the neuron stimulates the release of the neurotransmitter into the synaptic cleft, which, in turn, determines whether another electrical impulse is generated
126
NTs most commonly affected by psych meds
acetylcholine, norepinephrine, dopamine, serotonin, GABA, glutamate
127
receptor
molecules situated on the cell membrane tat are binding sites for NTs
128
big 3 for side effects are "anti-HAM"
antiHistamine = sedation and weight gain
antiAdrenergic = hypotension and dizziness
antiMuscarinic = anticholinergic effects (dry--can't see, pee, spit, poop)
129
antianxiety/anxiolytics
(minor tranquilizers) benzodiazepines and buspirone/buspar
130
benzodiazepines
(clonazepam, diazepam, alprazolam) most common, highly addictive (dont stop abruptly)
work by depressing the CNS and potentiate the effects of inhibitory NT GABA, for short term use only
131
busprione/buspar
non-benzo med for anxiety, doesn't depress the CNS, works through multiple mechanisms and is categorized as a selective serotonin subtype 1 A partial agonist
must be taken daily for effectiveness, not prn
132
benzo safety
short term use only due to risk of tolerance and dependence, don't stop taking abruptly, boxed warning against combining with opioids or other CNS depressants due to increased risk of death, drowsiness/confusion, orthostatic hypotension, congenital manifestations especially if used in 1st trimester, caution with elderly due to risk of falls, impaired cognition, and paradoxical excitement
133
antidepressants
also used to treat anxiety, OCD, PTSD, bulimia, migraines, neuropathic pain, etc
work by increasing the concentration of serotonin, dopamine, and/or norepinephrine
134
MAOI
first "antidepressant" drug, monoamine oxidase inhibitor. very effective but many potentially deadly food and drug interactions
patient must avoid a diet high in tyramines (pickled, smoked, fermented and aged foods) because it can lead to HTN crisis, death
135
tricyclic antidepressants (TCAs)
next drug developed for depression and were first line for many years. not as effective as MAOIs but less interactions.
increase norepinephrine but are also "anti-HAM) leading to many side effects. also block sodium channels which makes them very deadly in cases of overdose so some providers won't prescribe more than a week at a time
136
SSRIs (selective serotonin reuptake inhibitors) and SNRIs (serotonin-norepinephrine reuptake inhibitor)
became the preferred first-line treatment for depression
137
atypical antidepressants
(such as bupropion, vilazodone, and mirtazapine) have unique MOAs
138
atypical antipsychotics (for depression)
most recent addition (aripiprazole/Abilify) that increase the availability of serotonin and dopamine and are used as adjuncts to antidepressants
139
clinical pearls for antidepressants (important)
1) as antidepressant drugs take effect and mood begins to lift, individuals may have increased energy to implement a suicide plan. nurses should be alerted to sudden lifts in mood.
2) all antidepressants carry an FDA black-box warning for increased risk of suicidality in children, adolescents, and young adults up to the age of 25)
*always teach patients that antidepressants take up to a month to reach full effect*
140
antidepressant safety
drug/food interactions (especially MAOIs)
BBW increased risk of suicide
discontinuation syndrome
Anti-HAM side effects (especially TCAs)
serotonin syndrome, hyponatremia, increased risk for bleeding, sexual dysfunction, GI upset (SSRIs/SNRIs)
141
serotonin syndrome
can be deadly, need to immediately stop meds, signs/symptoms: diarrhea, shaking, elevated BP, unstable vitals, will be hospitalized until symptoms stop
142
mood stabilizing agents
for years, drug of choice for bipolar mania was lithium carbonate (doesn't work for bipolar depression)
drugs in the class of anticonvulsants are now approved
antipsychotics (2nd gen atypical)
143
lithium
a salt found in mineral springs, takes 7-10 days to reach full effect; it competes with sodium for receptor sites so anything that depletes sodium will make more receptor sites available and increase the risk for lithium toxicity
if sodium and water increase, lithium levels go down and vice versa. patients must maintain regular dietary sodium and fluid intake
very narrow therapeutic window
acute mania: 1.0-1.5 mEq/L
maintenance: 0.6-1.2 mEq/L
144
lithium toxicity early signs
levels over 1.5 mEq vomiting/diarrhea, levels over 2 can cause tremors, sedation, and confusion
levels over 3.5 can cause seizures, cardiovascular collapse, coma, and death
145
mood stabilizer safety
many drugs can increase or decrease their effectiveness
anticonvulsants have warning for increased suicidal thoughts
stevens-johnson syndrome (especially lamotrigine and carbamazepine)- life threatening rash, starts with a flu-like feeling
blood dyscrasias (esp valproate and carbamazepine) monitor for signs of infection or bleeding
risk of birth defects
146
antipsychotics
(aka neuroleptics, aka major tranquilizers) primarily used to relieve the symptoms of psychosis (hallucinations and delusions). used to treat schizophrenia, but also used for bipolar d/o, autism irritability, tourette's, as antiemetics and as adjuncts to antidepressants
primary MOA is blockade of the dopamine D2 receptors
first meds in this class - 1950s, known as first gen/typical/conventional antipsychotics and are associated with a high level of extrapyramidal symptoms (EPS)
147
atypical/2nd gen antipsychotics
developed due to high rate of EPS
148
atypicals (antipsychotics)
not only block the D2 receptor but also block the serotonin 5HT2A receptor leading to less EPS, but have high metabolic symptoms
patients need to be monitored for weight changes and cholesterol levels
149
3rd gen atypicals
such as aripiprazole/Abilify, have a unique profile
dopamine partial agonists
150
mnemonic for extrapyramidal symptoms
ADAPT
AD= acute dystonia (oculogyric crisis -eyes roll back, muscle spasms of the face, neck and throat) treat with IM/IV benztropine or diphenhydramine
A= akathisia (restlessness) and akinesia (absent/impaired movement)
P= pseudo parkinsonism (tremor, shuffling gait, drooling, rigidity) stop meds will stop symptoms
T= tardive dyskinesia (bizarre face and tongue movements; this is permanent so monitor with the AIMS- abnormal involuntary movement scale)
151
antipsychotic safety issues
BBW for increased risk of death in elderly dementia patients, many can cause long QT syndrome leading to arrhythmias/Torsade's
clozapine- seizures; agranulocytosis (watch for s/s infection, flu-like symptoms) check neutropenic levels with blood draw
EPS, neuroleptic management syndrome (NMS) monitor for muscle rigidity and fever- leads to rhabdo, metabolic syndrome- atypicals, anti-HAM
152
antiparkinsonism/anticholinergic
used to counteract EPS
restore natural balance of acetylcholine and dopamine in the brain
most common side effects are anticholinergic in nature
may also cause sedation and orthostatic hypotension
most common used: benztropine/cogentin, diphenhydramine/benadryl, and at times artane
153
sedative/hypnotics
short term management of various anxiety states and treatment of insomnia (diazepam/valium, temazepam/restoril, phenobarbital)
also used for epilepsy and alc withdrawal
selected agents are used as anticonvulsants, as pre-op sedatives
MOA is CNS depression, potential for dependence
154
sedative/hypnotic safety
CNS depressants shouldn't be combined due to additive effects that lead to respiratory depression and death
abnormal thinking and behavioral changes have occurred
aggressiveness. hallucinations, and suicidal ideation have been reported
155
ADHD agents
CNS stimulants increase levels of dopamine, norepinephrine, and serotonin, but MOA is unclear
two main classes of stimulants are amphetamines and methylphenidate
the non-stimulants include alpha-agonists (clonidine), NRI (atomoxetine) and NDRI (bupropion)
- monitor HTN and dizziness
156
ADHD med safety
CNS stimulants shouldn't be used with CVD due to risk of sudden death - monitor BP and pulse
stimulants have potential for misuse, can cause insomnia, GI upset, weight loss, tics, agitation, and psychosis
teach patients not to take other meds including OTC unless chacked with provider
bupropion shouldn't be used with history of seizures or eating disorders
alpha agonists can cause sedation and hypotension, don't stop abruptly
