pt. centered care, evidence based practice, teamwork, safety → quality & informatics
What are the qualities of therapeutics?
caring, attending and advocating
Difference between mental health and mental illness?
mental health involves emotional, psychological and social well-being (affected by various influences) vs mental illness affects the emotional, cognition and behavior and is the result of flawed biological, psychological social processes (treatable)
What are the prominent theories/models?
psychoanalytic theory (sigmund freud), psychosocial theory (erik erikson), interpersonal theory (herbert sullivan), humanistic theory (abraham maslow), cognitive theory (aaron beck)
Describe the psychoanalytic theory
sigmund frued (father of psychiatry)
psychological disturbances due to early trauma/incidences
three layers of mental activity (conscious, preconscious, unconscious)
interactive agents (ego, superego, ID)
What is psychodynamic theory?
trying to understand at unconscious level for truth; r/t transference and countertransference
What are erikson’s psychosocial stages?
infancy (0-1) - trust vs mistrust
early childhood (1-3) - autonomy vs shame/doubt
play age (3-6) - initiative vs guilt
school age (7-11) - industry vs inferiority
adolescence (12-18) - identity vs confusion
early adulthood (19-29) - intimacy vs isolation
middle age (30-54) - generativity vs stagnation
old age (65+) - integrity vs despair
Describe the interpersonal theory
herbert sullivan
believes relationships are basics for mental health/illness
interpersonal therapy focuses on the here and now

abraham maslow
5 key needs that motivate human behavior and helps fulfillment
physiological → safety needs → love and belonging needs → esteem needs → self actualization → self transcendence
Describe the cognitive theory
aaron beck
believed cognitive appraisals lead to emotional responses
What is cognitive-behavioral therapy?
seeks to identify negative patterns that lead to negative emotions

medications that affect brain chemistry and influence mood, perception, behavior and cognition
What are pharmacokinetic interactions?
when one drug alters another drug’s level in the body (ex. one drug speeding another's metabolism)
What are pharmacodynamic interactions?
when drugs act at the same or interrelated receptor sites (two drugs amplify or oppose each other’s effects)
What are the types of psychotropics?
A - antipsychotics
M - mood stabilizers
A - antidepressants
A - anxiolytics
Antipsychotics
1st generation and 2nd generation
used for schizophrenia, bipolar disorder, and treatment-resistent depression
Mood stabilizers
lithium and anticonvulsants
typically used for bipolar disorders
Antidepressants
SSRIs, SNRIs, SNDIs, NDRIs, SARIs, NRIs, TCAs, MAOIs
used for depression and PTSD
Anxiolytics
buspar, benzodiazepines, hypnotics
used for anxiety and panic disorder
only help SYMPTOMS of anxiety not source
What are the 8 types of antidepressants?
S - SSRI (selective serotonin reuptake inhibitors)
S - SNRI (serotonin-noradrenaline reuptake inhibitors)
S - SNDI (serotonin-norepinephrine-dopamine reuptake inhibitor)
N - NDRI (norepinephrine and dopamine reuptake inhibitors)
S - SARI (serotonin agonist and reuptake inhibitors)
N - NRI (norepinephrine reuptake inhibitor)
T - tricyclic antidepressant
M - MAOI (monoamide oxidase inhibitor)
SSRI?
block the reuptake of serotonin in the synapse
fewer side effects (does not inhibit other receptors)
ex. fluoxetine, sertraline, paroxetine, citalopram, escitalopram, vortioxetine
SNRI?
block the reuptake of both serotonin and norepinephrine
ex. venlafaxine, duloxetine, desvenlafaxine
SNDI?
increases serotonin and norepinephrine transmission by blocking presynaptic a2-noradrenergic receptors
ex. mirtazapine
NDRI?
inhibits the reuptake of norepinephrine and dopamine
inhibits nicotinic acetylcholine receptors = smoking cessation
ex. bupropion
SARI?
at high doses, inhibits the reuptake of serotonin and acts as a serotonin antagonist
ex. trazadone (low doses used for insomnia)
NRI?
blocks presynaptic norepinephrine transporters (NETs) → inhibits reuptake of norepinephrine
ex. atomoxetine
Tricyclic antidepressants?
blocks presynaptic transporter protein receptors for norepinephrine and (lesser degree) of serotonin → inc. NE at synapse
dirty drug: anticholinergic effects, sedation, weight gain, dizziness and hypotension
used in difficult cases of depression
MOI?
increase concentration of monoamines by inhibiting MAO (enzyme that destroys monoamines)
monoamines: neurotransmitter (catecholamines and indolamines)
can cause hypertensive crisis if taken with other medications such as pseudoephedrine or foods with tyramine (aged + fermented and drinks)
What are the main types of mood stabilizers?
lithium & anticonvulsants
What is lithium?
causes alterations in calcium and protein kinase c-mediated processes = effects on electrical conductivity
low therapeutic index therefore regular monitoring of blood lithium levels and sodium
sodium depletion = retained lithium in kidneys
excess sodium = dec. lithium
long-term use inc. kidney and thyroid disease
What are anticonvulsants?
alter mvmt of sodium, potassium, calcium, and magnesium → more stabilized and less excitable cell membranes (some enhance GABA an inhibitory neurotransmitter that regulates neuron excitability)
ex. valproate → divalproex sodium (Depakote) and valproic acid (Depakene) inhibit GABA catabolism for bipolar disorder
ex. lamotrigine (Lamictal); inhibits release of glutamate and aspartate (risk for steven johnson’s syndrome; assess for rash) for bipolar disorder
carbamazepine (Tegretol): stabilizes inactive state of sodium channels in neurons. for rapid-cycling bipolar disorder; regular monitoring of cbc (risk for agranulocytosis and aplastic anemia)
What are the other types of mood stabilizers?
ozcarbazepine (Trileptal), gabapentin (Neurontin), and topiramate (Topamax)
What are the types of antipsychotics?
1st generation/conventional/typical and 2nd generation/atypical
What are 1st generation antipsychotics?
aka neuroleptics/dopamine receptor agonists
binds to d2 receptors and reduce dopamine transmission
dec. pos symptoms in schizophrenia
side effects: dystonia (muscle stiffness), akathisias (restlessness), tardive dyskinesia, parkinsonism
life threatening: neuroleptic malignant syndrome (severe muscle regidity, confusion, agitation, inc. temp, HR & BP)
also blocks muscarinic cholinergic receptor which leads to blurred vision, dry mouth and dec. urination
ex. haloperidol (Haldol) and fluphenazine (Prolixin)
What are 2nd generation antipsychotics?
aka serotonin-dopamine antagonists (SDAs)
fewer extrapyramidal symptoms
fda approved for bipolar and depression along w/ schizophrenia
ex. clozapine (Clozaril) → agranulocytosis
ex. olanzapine (Zyprexa): sedating give at bedtime
ex. risperidone (Risperdal): orthostatic hypotension and sedation → falls
quetiapine (Seroquel): good for pt. w/ poor sleep, risk for orthostatic hypotension
What are the medications associated with antianxiety/anxiolytics?
B - buspirone/buspar
B - benzodiazepines
S - short-acting hypnotics
M - melatonin receptor agonists
A - antidepressants
What is busipirone/buspar?
high affinity for serotonin receptors
no risk for addiction
doesn’t cause immediate sedative and euphoric effects
What are benzodiazepines?
promotes activity of GABA
high risk for abuse and connections to dementia
sedative and hypnotic effects
reduces neuronal excitement - used for seizures and alcohol withdrawals
ex. lorazepam (Ativan), alprazolam (Xanax), diazepam (Valium), clonazepam (Klonopin)
What are short-acting hypnotics?
demonstrates selectivity for GABA-A receptors
