25
prototype for benzodiazapines class
lorazepam
26
what does "pam" usually indicate
benzodiazepine
27
FYI: Lorazepam combines with gaba receptors = calms the CNS down = decrease CNS functioning = calms people down and helps them to sleep
:)
28
What drug:
anti-anxiety, sedation, anesthesia induction and maintenance, seizures (status epilepticus), sedation for mechanical ventilation, alcohol withdrawal symptoms
Lorazepam
29
should a pregnant girl take Lorazepam
NO!
30
can Lorazepam cause orthostatic hypotension?
yes
31
the effect is the opposite of what we intended it to have
paradoxical reactions
32
Important potential interactions for Lorazepam
increased effect with other CNS depressants
33
4 important side effects for Lorazepam
- drowsniness
- excessive sedations
- impaired motor coordination
- confusion
34
Patient teaching for Lorazepam
- don't take with other CNS depressants (ex. alcohol, other sleeping pills)
- don't take if pregnant/notify doctor
- keep in a secure place/out of reach of children/med abusers
35
Nursing considerations for Lorazepam
- aspirate prior to IV injection (cause gangrene if not in vein) , also give very slowly with IV!!
- if pt. is smoker = they will require larger doses
- monitor ambulation
36
Is diazepam (valium) a prototype

antidote to benzodiazepines
flumazenil
44
does flumazenil have a long or short half-life
short
45
drugs used to treat insomnia
- benzodiazepines
- non-benzodiazepines
- antidepressents
- barbiturates
46
FYI: the meds for insomnia tend to reduce REM sleep = allow us to sleep at night, but not as deep as we could get = often tired throughout the day = nurses need to encourage use of non-pharmacologic measures for sleep
:)
47
is zolpidem (ambian) a diazepine
no, it's a non-benzodiazapine
48
is zolpidem a non-diazepine prototype
yes
49
what is zolpidem used for
sleep/insomnia treatment
50
nursing considerations for zolpidem

- pt's will always be at fall risk when on this med
51
pt/family teaching for zolpidem

sleep/insomnia
53
does temazepam have similar characteristics as other benzodiazepines
yes
54
is phenobarbitol given commonly for sleep
no
55
T/F: barbituates tend to commit suicide
TRUE!
56
problem with phenobarbitol
- it's a barbituate = suicide?
- develops tolerance easily to CNS effects = takes more to help fall asleep (respiratory system doesn't develop this tolerance = unsafe)
57

| - seizures
58
nursing considerations for a patient taking sedative/hypnotics

59
disease caused by destruction of neurons and there's anatomical changes within brain and decrease in acetylcholine
alzheimer's disease
60
Degenerative brain disease that usually starts with some forgetfulness progressing to minor memory loss and confusion. Unfortunately, the disease progresses to profound irreversible mental impairment. It is not a normal aspect of aging.
alzheimer's disease
61
symptoms of what disease:

alzheimer's disease
62
drugs for the treatment of alzheimer's disease
indirect acting cholinergics (anticholinesterases)
63
prototype of indirect acting cholinergics (anticholinesterases)
donepezil (aricept)
64
T/F: indirect acting cholinergics (anticholinesterases) can stop the progression of alzheimer's disease
FALSE! They can slow it down, but not stop it
65
why do we even give indirect acting cholinergics (anticholinesterases)
- improve ADLS
- improve behavior
- improve cognition
66
what drug:
| improved memory, function and behavior through elevating acetylcholine concentration in CNS
donepezil
67
important adverse effects of donepezil
- GI issues (A, N, V, D, cramping) (because we're stimulating PNS of ANS)...most will go away with continued use
68
nursing considerations for donepezil
- monitor for cognitive function (can pt. be responsible enough to take their own meds)
- monitor for GI bleeding, especially if on NSAIDS
- monitor for respiratory function, especially for asthma or COPD pt's
- walk through ANS (cholinergic = decrease in bronchoconstrition)
- monitor for safety issues/depression
69
pt. teaching for donepezil
- does not cure/prevent disease, just slows it down
- report GI bleeding
- encourage to take with food/milk to decrease GI upset
70
a disorder in children ages 4-17, and can last into adulthood. It can lead to difficulties in school, jobs, and interpersonal relationships
ADHD
71
why do kids usually get diagnoses with ADHD so early in life
because ti's very noticeable when they start school
72
2 kinds of meds used for ADHD
stimulants & non-stimulants
73
are stimulants or non-stimulants more common
stimulants
74
T/F: stimulants are sympathomimetic drugs
T, so they increase fight or flight = improve alertness & focusing
75
can ADHD last into adulthood
yes
76
T/F: non-stimulant drugs are like antidepressents
true

80
drug of choice for ADHD treatment
amphetamine
81
what drug:
| stimulates the CNS to improve alertness, awakeness, mood, and attention. Causes a paradoxical sedation effect in ADHD
amphetamine (dextroamphetamine)
82
contraindications of ampethamine
- hyperthyroidism = increase HR (drug already increases HR)
- diabetes = increase BS (drug already increases HR)
- bipolar = can potentially throw someone into a manic episode
83
interactions for amphetamine
- alkaline drugs decrease elimination
- acidic drugs increase excretion

T/F: atomoxatine takes a while for therapeutic affects, fpeak is 1-2 hours, onset 2-4 weeks
T, this drug is similar to antidepressant mechanisms = takes a couple weeks to show alleviation/therapeutic effect of ADHD symptoms
89
what drug:
| improves attentiveness and decrease distraction and forgetfulness
atomoxatine
90
use of MAOI's
- MAOI is a type of depressents
| - MAOI breaks down norepinephrine = norepinephrine re-uptake inhibitor - excessive norepinephrine
