Chapters 17-20 Flashcards
What are the three medically approved usages for cns stimulants
- adhd in children
- narcolepsy
- reversal of respiratory distress
This category of sedative-hypnotics does not have lingering side effects
short-acting hypnotics
if your patient is having a seizure, what is the first medication you would administer
lorazapam (ativan)
this disorder affects extrapyramidal motor tract including controls posture, balance, and locomotion
Parkinson’s disease
This drug in part works by facilitating transmission of levodopa to brain cells for conversion to dopamine
carbidopa-levodopa (sinemet)
your patient is complaining of difficulty falling asleep. What are some recommendations to provide?
- always start with non-pharmacologic before utilizing a sleeping agent, encourage your patient to try to maintain a sleep schedule, and avoid napping during the daytime, don’t consume anything with caffeine within 6 hours of bedtime, maintain low lights during hours of sleep, avoid electronics.
the dysregulation of serotonin, norepinephrine, and dopamine is due to this disorder
ADHD
long-acting sedative-hypnotics are utilized to control which neurologic disorder
epilepsy
a concerning adverse outcome for your patient on phenytoin (dilantin) is
gingival hyperplasia
what are defining characteristics of Parkinson’s
tremors, gait disturbance, bradykinesia, rigidity. additional characteristic symptoms: absence of arm swing, pill-rolling motions of hands, tremors more prevalent at rest, masked face, involuntary tremors of head and neck.
this medication functions by preventing peripheral COMT degradation to allow more levodopa to reach the brain
entacapone (comtan)
this drug is short-acting in the use of sleep, and does not cause a risk for withdrawal or tolerance
ramelteon (rozerem)
this category of drug works by releasing norepinephrine and dopamine from the brain and sympathetic nervous system
amphetamines
this drug works by binding to receptors in the limbic system and reticular formation to reduce anxiety and/or panic disorders
alprazolam (xanax)
your pregnant client asks if she can continue taking her phenobarbital for her epilepsy. as the nurse, how would you respond?
yes, this is safer in pregnancy, and has less caution than other antiseizure drugs.
what are the two neurotransmitters that are deficient in Parkinson’s?
dopamine and ACh
your patient with Parkinson’s is taking selegiline and asks if they need to follow any dietary restrictions. as the nurse, what is your best response?
you would need to avoid foods containing tyramine. (aged foods, red wine, and bananas)
what encompasses the severe stage of alzheimer’s
forgets previously known individuals, all recent experiences are forgotten, inability to converse, swallow, or ambulate
this drug works by affecting changes in dopamine transportation in patients with narcolepsy
methylphenidate
what is imperative to assess prior to administering alprazolam (xanax)
blood pressure, respiratory rate, and oxygen saturations - xanax can cause lethargy, drowsiness, hypotension, and respiratory suppression
what is status epilepticus
a seizure lasting longer than 5 minutes, or multiple seizures with no recovery in between
your patient with Parkinson’s explains he has been taking his medication as prescribed and at the correct times, but is starting to notice his symptoms are presenting before his next dose is due. as the nurse what do you presume is the causative factor
on-off syndrome. it’s possible he may need to increase his dosage/frequency.
this medication works to improve memory loss in Alzheimer’s disease
rivastigmine (exelon)
this can be given in high doses to stimulate respirations
caffeine
