Psychiatric drugs and Bipolar disorder Flashcards
Bipolar is characterized by
alternating feelings of extreme sadness and extreme mania
significantly impacts social + occupational functioning.
What are some non-pharmacological interventions to treat bipolar disorder
-better sleep, reduce stress, improve nutrition.
-support groups.
-ECT
Pharmacological interventions for bipolar disorder is highly
individualized based on severity and predominant symptoms
what is a problem with bipolar disorder pharmacologic interventions
nonadherence is a serious problem (do to highs, feeling great)
Lithium drug interactions
-diuretics= increase risk of lithium toxicity (lasix)
-NSAID=
(can increase lithium levels)
-antithyroid drugs, drugs containing iodine cause increase of hypothyroid effect.
-haloperidol causes increase of neurotoxicity.
-SSRI’s, MAOIs, dextromethorphan may result in SES.
-some herbal, some food.
how often should serum levels be monitored when a patient is taking lithium
Q1-3 days initially and 2-3 months after.
before and after lithium treatment, what should the nurse assess for
bipolar disorder before and after treatment.
and
weight changes, edema, changes in skin turgor
what baseline levels should the nurse obtain when a patient is taking lithium
thyroid, kidney, cardiac function, electrolyte
what are S+S of lithium toxicity
- Nausea/Vomiting
- Persistent diarrhea
- Coarse trembling of hands or legs.
- Frequent muscle twitching such as pronounced jerking of arms or legs.
- Blurred vision.
- Marked dizziness.
- Difficulty walking.
- Slurred speech.
- Irregular heart beat.
- Swelling of the feet or lower legs.
what should the patient be told about table salt when on lithium, and what should the nurse monitor
contiune to take in dietary table salt to maintain osmotic hydration but do not over do it. The nurse should monitor sodium levels
what does dehyration or over hydration do to lithium levels
-dehydrated increases lithium
-over hydrated decreases lithium levels.
pts who increase exercise, or are N/V/D should be watched.
Etiology schizophrenia
etiology remain unknown
What is the genetic component of schizophrenia
5-10 times greater risk if a first degree relative has disorder.
What neurotransmitter is imbalanced in schizophrenia
- overactive dopaminergic pathways in basal nuclei
- association with dopamine type 2 (D2) receptors.
(antipsychotic drugs block receptors)
what is the drug of choice for schizoprenia treatment?
second generation (atypical) antipsychotics
-risperidone, olanzapine, quetiapine, and aripiprazole
What route are most antipsychotic drugs administered
orally
during the intial treatment of psychoses what should the nurse know about drug dosing of antipsychotics
first doses of antipsychotic drugs may be higher than normal
-produces sedation if patient agitated, aggressive, or posing danger to others
What drug is given to relax patients in sychoses and may allow intial dose of antipsychotic medication to be reduced
benzodiazepenes
(Lorazapam) given IM
How long do acute symptoms of psychoses take to resolve
3-7 days
What does extrapyramidal side effects (EPS) refer too?
locations in the CNS associated with postural and automatic movements
(1st gen) - haloperidol
What type of movements are associated with extrapyramidal side effects
Acute dystonia (contractions)
Akathisia (restless, inability to sit still)
Parkinsonism
Tardive dyskinesia (TD) (common with typical anti-psychotics) - involuntary, repetitive movements
Think ADAPT
Neuroleptic malignant syndrome (NMS) treatment includes
antipyretics, electrolytes, muscle relaxants.
Neuroleptic malignant syndrome symptoms
high fever, diaphoresis, muscle rigidity, tachycardia, BP fluctuations
(Think - “ fever”
Fever, encephalopathy, vital signs unstable, extra sweaty, rigidity
neuroleptic malignant syndrome can deteriorate to
stupor or coma
