25
first step of nursing process for schizophrenia (biological interventions)
-history & physical assessment -bloodwork -rule out medical or physiological impact
26
second step of nursing process for schizophrenia (biological interventions)

27
third step of nursing process for schizophrenia (biological interventions)
-pharmacotherapy: typical antipsychotics -task description
28
fourth step of nursing process for schizophrenia (biological interventions)

how do typical antipsychotics work
they block dopamine receptors
31
side effects of typical antipsychotics
-anticholinergic side effects (dry mouth, urinary retention, tachycardia) -extra pyramidal side effects (4 categories) -sedation -increase HR -decerased BP -increased prolactin -agitation -nausea -dyspepsia

40
side effects common to olanzapine
weight gain, tachycardia, increased risk for diabetes, sedating, bone marrow suppression
41
what atypical antipsychotics can be prescribed if the pt is prone to weight gain?
ziprasidone (zeldox) aripiprazole (abilify)
42
side effects common in risperidone
increased prolactin enlarged breast irregular menses -sexual dysfunction sedation hypotension increased dose=EPS is a concern
43
side effects common in clozapine
agraunulocytosis seizures tachycardia weight gain sedating
44
side effects for atypical antipsychotics
metabolic syndrome sedation & hypotension common
45
what is metabolic syndrome?
-significant concern in most atypical antipsychotics -risk for altered glucose metabolism diabetes (hyperglycemia), dyslipidemia (cholesterol changes), abdominal obesity weight gain -comorbidity of serious mental illness and metabolic syndrome contributes to the reduced lifespan of those diagnosed with a serious mental illness
46
what atypical antipsychotics are highest risk for metabolic syndrome

life-threatening neurological disorder most often caused by an adverse reaction to antipsychotic medication -usually occurs when medication is stopped abruptly -if detected early prognosis is good
49
what causes NMS
sudden, marked reduction in dopamine activity, either from withdrawl of dopaminergic agents or from blockade of dopamine receptors seen when meds are stopped abruptly
