builds alliance with client, fam, health care team Establish a collaboration that fosters recovery
27
Building a schiz Therapeutic relationship: 2. Identification
client is aware of the issues they are facing and see the impact of the disorder Nurse must consider the phase of psychosis, pos/neg symptoms, keep client SAFE
28
Building a schiz Therapeutic relationship: 3. Exploitation
client explores interventions and learns how to recognize triggers and express difficulties and need for assistance setting clear limits on what actions and behaviors are acceptable, explaining what the plan of care includes, work with the client toward recovery and learn to live with mental illness

FIRST LINE TREATMENT for SCHIZ Risperidone, clozapine, apriprazole ~done and pine
38
SGA pharm action
Blocks serotonin more than FGA and blocks less of dopamine, norepi, histamine, and acetylcholine
39
SGA Therapeutic uses
Relief of pos and neg symptoms of schiz, psychosis from levodopa therapy, impulse control disorders, psychotic manifestations from bipolar disorder
40
SGA Client education
minimize weight gain → healthy/low cal diet, monitor weight, exercise
41
SGA adverse effects
Metabolic syndrom: increases risk of heart disease, stroke, type 2 Symptoms: weight gain, increased BP & glucose Monitor: daily weight, HDL, cholesterol, triglyceride levels Agitation, dizziness, sedation, sleep disruption → report to provider - Blood tests needed to monitor agranulocytosis
42
Clozapine tablet (not first line) interventions
Adverse: agranulocytosis (low WBC) Baseline & regular monitoring of WBC and RBC weekly Notify provider of infection (fever, sore throat, mouth lesions) Low risk of EPS
43
What is FGA
chlorpromazine, haloperidol, fluphenazine -Used to control positive symptoms of psychotic disorders
44
FGA Pharmalogical action
Blocks dopamine more than SGA, acetylcholine, histamine, and norepi receptors in the brain
45
FGA Contraindication
agranulocytosis (WBC less than 3,000) → observe for infection and notify provider if occurs
46
FGA Common side effects
anticholinergic- blurred vision, dry mouth, photophobia, urinary retention, conspitaiton, tachycardia
47
FGA Serious side effects
extrapyramidal adverse effects → monitor EPS 1. Acute dystonia: severe spasm of tongue, neck, face, back Intervention: monitor 1-5 days after first dose Treatment: benztropine 2. Pseudoparkinsonism: bradykinesia, rigidity, shuffling gait, drooling, tremors Intervention: monitor first month after first dose & reduce risks of falling Treatment: benztropine or trihexyphenidyl 3. Akthisia: inability to sit or stand still, constant pacing and agitation Intervention: Monitor first 2 months after first dose & increased risk for suicide Treatment: Beta blockers, lorazepam/diazepam, or benztropine 4. Tardive dyskinesia: Involuntary lip smacking, tongue movements, arms, legs, trunk Intervention: lower dosage or switch to SGA & teach client purposeful muscle movement helps to control the involuntary TD No treatment 5. Neuroendocrine effects: gynecomastia (male breasts), weight gain, menstrual irregularities Intervention: monitor weight & notify provider if manifestations occur 6. Neuroleptic malignant syndrome (fatal): sudden high fever, BP fluctuations, diaphoresis, tachycardia, muscle rigidity, decreased LOC, coma Intervention: can occur within first week of treatment, stop med, monitor vitals, apply cool blanket, increase fluids, !Immediate transfer to the ICU! Treatment: dantrolene or bromocriptine to induce muscle relaxation, medication to treat arrhythmias, antipyretics for fever 7. Orthostatic hypotension Interventions: monitor BP and HR, hold med until provider is notified if there is a significant decrease in BP or increase in HR, increase fluid intake 8. Sedation Intervention: take med at bedtime to avoid daytime sleepiness, do not drive 9. Seizures Increased risk in clients who have an existing seizure disorder Intervention: increase in antiseizure med can be necessary & report seizure activity to provider 10.

Skin effects: photosensitivity (sunburn), contact dermatitis Education: avoid excessive exposure to sunlight, use sunscreen, and wear protective clothing, avoid direct contact with the med
