side effects of antipsychotics SHE WAS ME

S - sedation H - hypotension E - extrapyramidal W - weight gain A - anticholinergic S - sexual dysfunction M - metabolic (glucose tolerance) E - endocrine

Which effects do most antipsychotic medications exert on the central nervous system (CNS)?

They depress the CNS by blocking the postsynaptic transmission of dopamine, serotonin, and norepinephrine.

mutism

absence of verbal speech

what disturbances occur in schizophrenia?

before age 12 = severe form

meds to prevent extra pyramidal effects

benadryl cogentin

negative symptoms

blunted affect poverty of thought (alogia) loss of motivation (avolition) inability to experience pleasure or joy (anhedonia)

schizophrenia maintenance therapy

decanoate Haldol & Proloxin (fluphenazine) lasts 2-4 weeks, no need for daily meds

confabulation

pharmacology & schizophrenia

goal: reduce psychotic symptoms antipsychotics (dopamine agonists) - targets positive symptoms atypical antipsychotics (dopamine/serotonin antagonists) - diminish positive symptoms& lessen negative symptoms

positive symptoms of schizophrenia

hallucinations delusions disorganized speech (LOA) bizarre behavior

looseness of association

haphazard, illogical, confused thinking, interrupted connections in thought

A nurse knows that a physician has ordered the liquid form of the drug chlorpromazine  rather than the tablet form because the liquid:

has a more predictable onset of action. A liquid phenothiazine preparation will produce effects in 2 to 4 hours. The onset with tablets is unpredictable.

perceptual distortions in schizophrenia

illusions hallucinations

abnormal thought processes

impaired reality testing fragmentation of thoughts thought blocking loose association echolalia distorted perception of the environment neologisms magical thinking inability to conceptualize meaning in words or thoughts inability to organize facts logically delusions associated with thought processes or content

word salad

words or phrases are connected meaninglessly

"A client who is newly diagnosed with schizophrenia tells the nurse, ""The aliens are telling me that I am defective and need to be eliminated."" Which response by the nurse is most appropriate initially?"

"I want you to agree to tell staff when you hear these voices."

onset of schizophrenia

- abrupt or insidiuous - most slow development of symptoms - ongoing psychosis (diminishes w/age) alternates w/relative recovery

suicidal assessment

- sex (men>women) - age (increased in age) - depression

A client with schizophrenia is mute, can't perform activities of daily living, and stares out the window for hours. What is the nurse's first priority?

Assist the client with feeding.

A nurse must administer a medication to reverse or prevent Parkinson-type symptoms in a client receiving an antipsychotic. The medication the client will likely receive is:

Benztropine, trihexyphenidyl, or amantadine are ordered for treatment of Parkinson-type symptoms. Diphenhydramine provides rapid relief for dystonia. Propranolol relieves akathisia. Haloperidol can cause Parkinson-type symptoms.

extrapyramidal effect

acute dystonic reaction akathisia parkinsonism

A client receiving haloperidol reports a stiff jaw and difficulty swallowing. The nurse's first action should be to:

administer an as-needed dose of benztropine I.M. as ordered.

disorganized schizophrenia

extreme social withdrawal disorganized speech or behavior flat or inappropriate affect silliness unrelated to speech stereotyped behaviors grimacing mannerisms inability to perform activities of daily living

suicide pathophysiology/etiology

genetic impulsivity serotonin dysfunction post traumatic brain injury

A nurse knows that a physician has ordered the liquid form of the drug chlorpromazine rather than the tablet form because the liquid:

has a more predictable onset of action. A liquid phenothiazine preparation will produce effects in 2 to 4 hours. The onset with tablets is unpredictable.

cognitive symptoms in schizophrenia

inattention, easily distracted impaired memory poor problem-solving skills poor decision-making skills illogical thinking impaired judgment

tardive dyskinesia

involuntary movement of mouth (tongue writhing, tongue protrusion, teeth grinding, lip smacking), face & exremities can occur 6 mths after start of txt

types of delusions in schizophrenia

loss of reference (everything happening related to self) delusions of persecution delusions of grandeur somatic delusions (body is changing or responding unusually)

When discharging a client after treatment for a dystonic reaction, an emergency department nurse must ensure that the client understands

the client must take benztropine as ordered to prevent a return of symptoms. (anticholinergic)

A client who is newly diagnosed with schizophrenia tells the nurse, The aliens are telling me that I am defective and need to be eliminated. Which response by the nurse is appropriate initially?

I want you to agree to tell staff when you hear these voices.

serotonin syndrome

agitation sweating fever tachycardia hypotension rigidity hyperreflexia coma death

extrapyramidal side effects s/s

akathisia = restlessness dystonia = muscle spasms & twitching motions pseudoparkinsonims = mask like face, rigidity, tremors, drooling, shuffling gait, dysphagia

NI for delusions

ask to describe delusion be open & honest in interactions to reduce suspiciousness focus on reality-based topics, rather than delusion encourage expression of feelings, focus on feelings that delusion generates set limits on how long talk about delusions if pt. obsesses do not argue or try to convince that delusion false validate if part of delusion real activities on a one-on-one basis alter routines (allow canned or packaged foods or food from home) recognize accomplishments & provide positive feedback for success

types of hallucinations

auditory (hearing voices) gustatory (taste) olfactory (smell) tactile (feel) visual (see)

how quickly do illusions & hallucinations diminish with txt?

first few days of txt delusions/hallucinations not as intense but these symptoms only rest takes 6-8 wks to respond

etiology schizophrenia

genetic (partially inherited) neuroanatomic or neurochem. factors (less brain tissue, cerebrospinal fluid, excess of dopamine & serotonin immunovirologic factors (viral exposure, cytokinesis)

psychotic features

hallucinations delusions

echopraxia

repeating the movements of another person

NI for Schizophrenia

assess pt's physical needs set limits on behavior when it interferes w/others maintain safe environment one-on-one interaction & progress to small groups as tolerated spend time w/pt. even if unable to respond monitor for altered thought processes maintain ego boundaries & avoid touching avoid overly warm approach, neutral best (less threatening) keep promises establish daily routines assist pt. to improve grooming & to accept responsibility for personal care sit w/pt. in silence if necessary brief, frequent contact w/pt. tell pt. when u are leaving tell pt. when u do not understand do not go along w/hallucinations or delusions simple concrete activities (puzzles, word games) reorient as necessary help establish what is real stay w/pt. if pt. frightened speak in simple, direct, concise manner reassure pt. that environment is safe remove from group situations if pt is too bizarre, disturbing/danger set realistic goals do not offer choice (initially), gradually assist in making decisions used canned or packaged food provide radio etc. at night for insomnia explain everything that needs to be done set limits for pt. if pt. unable to do so decr. excessive stimuli monitor for suicide risk assist in alternative means to express feelings, (music or art therapy)
