exam 2 study grid Flashcards
1
Q
trazodone
A
- tetracyclic antidepressant agent
- action: alters the effects of serotonin in the CNS
- pharmacokinetics: metabolism and exretion. extensively metabolized by the liver and minimal excretion of unchanged drug by the kidneys
- half life: 5 to 9 hours
- uses: major depression. off label use: insomnia, chronic pain syndromes
- contraindications: hypersensitivity; recover. after MI; concurrent electroconvulsive therapy; concurrent use of MAOI inhibitors or MAOI like durgs; angle closure glaucoma
- use cautiously in: cardiovascular disease. suicidal behavior; may increase risk of suicide attempt/ideation, especially during early treatment or dose adjustment; severe hepatic or renal disease; lactation
- side effects: potential for increased suicidal tendencies, sedation, dry mouth, agitation, postural hypertension, headache, arthralgia, dizziness, insomnia, confusion, and tremors. most common: HTN, dry mouth, drowsiness, suicidal thoughts
- nursing implications: monitor BP and pulse rate before and during initial therapy. Monitor ECG’s in pts with pre existing cardiac disease before and periodically during therapy to detect arrhythmias. assess for possible sexual dysfunction, assess for serotonin syndrome
2
Q
serotonin syndrome
A
- mental changes (agitation, hallucinations, coma)
- autonomic instability (tachycardia, labile BP, hyperthermi)
- neuromuscular aberrations (hyperreflexia, incoordination)
- GI symptoms
3
Q
Haloperidol
A
- indications: acute and chronic psychotic disorders, including schizophrenia, manic states and drug induced psychoses
- action: alters the effects of dopamine in the CNS. also has antichoinergic and alpha adrenergic blcking activity.
- therapeutic effects: diminished signs and symptoms of psychosis. improved behavior in children w/ tourette yndrome or other behavioral problems
- pharmacokinetics: concentrates in liver, crosses placenta; enters breast milk
- mostly metabolized by the liver
- half life: 21-24 hours
- contraindications: hypersensitivity; angle closure glaucoma; bone marrow depression; CNS depression; Parkinsonism; severe liver or cardiovascular disease; women lactating
- use catiously in: cardiac disease; diabetes; respiratory insufficiency; prosthetic hyperplasia; cns tumors; intestinal obstruction; seizures; patients at risk for falls
- side effects: torsades de pointes, hpotension, QT interval prolongation, tachycardia, ventricular arrhythmias, blurred vision, dry eyes, dry mouth, constipation, sizures, extrapyramidal reactions, tardive dysinesia, respiratory depression, neuroleptic malignant syndrome
- nursing implications: assess mental status (orientation, mood, behavior) prior to and periodically during therapy; assess positive and negative symptoms of schizophrenia; monitor BP and pulse prior to and frequently during the period of dose adjustments. may cause qt interval changes on ecg; monitor pt for onset of akathesia, which may appear within six hours of first dose and may be difficult to distinguish from psychotic agitation
4
Q
antipsychotics are used for…
A
- treat psychotic behavior and schizophrenia and other disdorders that may include violent or potentially violent behavior

5
Q
side effects of antipsychotics
A
- atypical antipsychotic medications have fewer side effects than typical
- a few of these side ffects of typical psychotropics arephotosensitivity, darkening of the skin from increased pimentation, anticholinergic effects such as dry mouth, and extrapyramidal symptoms
6
Q
extrapyramidal symptoms include
A
- drug induced parkinsonism (pseudoparkinsonism). symptoms appear 1-8 weeks after the pt begins the medication. akinesia, shuffling gait, drooling, fatigue, mask like facial expressions, tremors, and muscle rigidity
- akathisia: symptoms appear 2-10 weeks after the pt starts taking the medication. agitation and motor restlessness; appears more frequently in women
- dystonia: symptoms appear 1-8 weeks after the pt starts taking the medication. manifest as bizarre distortions or involuntary movements of any muscle group. tongue, eyes, face, neck, or any larger muscle group can become tightened into an unnatural position or have irregular pastic movements
requires immediate medical attention - tardive dyskinesia: symptoms appear within 1-8 weeks after the pt starts taking the medication. manifestations inclde rhthmic involuntary movements that look like chewing, sucking, or licking motions. frowning and blinking constantly are also common. previously thought to be irreversible, but can be treated with Ingrezza and Austedo. monitor for development of neuroleptic malignant syndrome. may also cause leukocytosis, elevated liver function tests, elevated ck
- fever, respiratory distress, tachycardia, seizures, diaphoresis, hypertension or hypotension, pallor, tiredness, severe muscle stiffness, loss of bladder control
7
Q
nursing considerations with antipsychotics
A
- monitor pts body movements using the abnormal involuntary movement (aim) FORM\
- monitor pts BP. may fluctuate from high to low
- observe for signs of Parkinsonism
- observe for signs of EPS or NMS and carefully monitor blood work for abnmormal results
- some antipsychotics interact with calcium containing medications. the pt should avoid taking antacids or calcium supplements 1-2 hours after oral administration
- antipsychotics medication should be discontinued slowly, never stopped abruptly
