Mental Health Week 2
Course of Schizophrenia
- Continuous without temporary improvement - Episodic with progressive or stable deficit - Episodic with complete or incomplete remission
Serious Mental Illness (SMI)
-difficulty with a wide range of functions -at risk for multiple physical, emotional, and social problems
temporal lobe function
-language comprehension -stores sounds into memory -allows expression of emotions
pt has symptoms of fever, muscle rigidity, and confusion what will you suspect is happening as the nurse?
-neuroleptic malignant syndrome (NMS)
frontal lobe function
-planning -decision making -insight -motivation -social judgement -voluntary motor ability starts here
disorganized behavior
-positive sign -decline is overall daily function -unpredictable and inappropriate emotions -lack of impulse control
parietal lobe
-receives and identifies sensory information -concept formation -body awareness -reading, math -right and left orientation
Other side effects of antipsychotics
-sedation -orthostatic hypotension -weight gain -photosensitivity -hormonal effects (sexual dysfunction) -seizures -extrapyramidal symptoms (EPS) -neuroleptic malignant syndrome (NMS) -blocks activity of dopamine receptors -reduces positive symptoms -tardive dyskinesia -anticholinergic effects (dries up) -serotonin syndrome (diarrhea)
Boundaries violations
-self disclosure (discussion personal info) -dual relationships (friend/family relationship) -becoming friends (seeing client outside of hospital) -physical contact (hugs, kisses, holding hands) -gift giving (do not accept money) -sexual contact *Don't reveal personal information to psych pt, no physical contact, don't see them outside of the hospital (Report to nurse supervisor if you see this)
Stages of Schizophrenia
1. Prodromal phase: impaired function before onset of active psychotic phase 2. Active/Acute phase: delusions, hallucinations, disorganized speech, disorganized behavior and negative symptoms such as flat affect (no expressions), avolition (lack of motivation), alogia (lack of conversation) ^^(these s/s must be present for a least 1 month) 3. Residual: functional impairment, abnormalities of affect, cognition, communication
Schizophrenia, how many die by suicide? %?
10%
These are the first line tx due to lower EPS risks
2nd gen antipsychotic drugs -these block serotonin and dopamine -target both - and + s/s -SE: hyperglycemia, wt gain, dizziness, sedation, sleep disruption

Anger vs. Aggression
Anger is a feeling Aggression is a behavior or action
3rd Gen antipsychotic drug
Aripiprazole -lower metabolic effects than 2nd gen -hypotension MOA: decreases dopamine SE: insomnia, akathisia (can't sit still)
Anticholinergics are used for what in pts w/ psychotic disorders
Benztropine and Diphenhydramine ^^ (can be given as an IM injection) -treat side effects -treat EPS
Examples of disorganized behavior
Catatonia (unable to move) Motor retardation (slow down of thought and movement) Motor agitation (movements that serve no purpose) Waxy flexibility (patient's limbs retain any position into which they are manipulated by another person) Echopraxia (imitation of the movements of another person) Negativism (negative thoughts) Stupor (near-unconsciousness) Impaired impulse control Gesturing or posturing (sitting odd or bizarre postures) Boundary impairment (impaired ability to sense where ones body or influence)
1st generation schizophrenia tx drugs
Chlorpromazine (Thorazine) (Strong like THORazine) monitor RR on this med because it can make it very low Haloperidol (Haldol)
This antipsychotic the pt needs to have weekly blood draws first 6 months due to risk of agranulocytosis (need WBC @ 5-10K)
Clozapine *Have to taper off, if ATI asks tho we want to discontinue this med if WBC are low^^^ *If pt gets flu like symptoms on this meds, they need to tell us since we stop doing blood draw after 6 months, they might be getting agranulocytosis
2nd gen antipsychotics
Clozapine (last resort drug) Risperidone Olanzapine Ziprasidone Asenapine (dissolves in mouth, absorbs fast) Paliperidone

Serotonin, what happens when this is high/low?
Low: Depression High: Anxiety -plays a role in sleep, hunger, mood, pain -hormonal activity -aggression and sexual behavior
Dopamine, what happens when this is high/low?
Low: Depression, Parkinson's Disease High: Schizophrenia, Mania -involved in fine muscle movement -integration of emotions and thoughts -decision making -stimulates the release of hormones (sex, thyroid, adrenal)
This antipsychotic med lowers BP, over time pt will gain weight "Obese starts with O"
Olanzapine

Paliperidone
We use this antidepressant for pts with psychotic disorders

This can happen when they body becomes tolerant to meds
Relapse

Sublimation and Altruism
Deutetrabenazine and Valbenazine treat/prevent what?
Tardive Dyskinesia
We don't want to remove restraints all at the same time T/F?
True
Need baseline EKG before giving this antipsychotic med because it can cause QT prolongation
Ziprasidone
