NUR 546 EXAM 1 WITH CORRECT
ANSWERS 2025
Dantrolene Therapeutic use / MOA correct answers >>
Muscle relaxant (adverse effect: muscle weakness)
Think "lean" as muscles relax
Peripherally acting (think distal)
Used to treat malignant hyperthermia
Dante's Inferno
Dantrolene adverse effects correct answers >> Adverse
effects
3 D's
Drowsiness, Dizziness, Diarrhea
Avoid alcohol/CNS depressants
Can cause Liver toxicity
Dantrolene Administration & client education correct answers
>> Administered via IV push or PO
Dantrolene Contraindications/precautions/interactions correct
answers >> Caution CNS depressant meds, alcohol and calcium
channel blockers (can cause cardiac dysrhythmias
Lidocaine Therapeutic use / MOA correct answers >> Local
anesthesia (can be topical)
,Labor - used for epidural or spinal anesthesia
Blocks the influx of Na through Na channels preventing
depolarization
Lidocaine Adverse effects correct answers >>
Lightheadedness (can cause hypotension when used for spinal
anesth.)
Too much can cause CNS stimulation (lidocaine - sugar cane -
sugar rush)
Restlessness, irritability, tremors, confusion, convulsions
After CNS stimulation resolves, CNS depressant effects occur
causing risk for resp. Arrest
Lidocaine Administration & client education correct answers
>> Avoid administering in eyes or broken skin
Use correct concentration and form
Lidocaine Contraindications/precautions/Interactions correct
answers >> Clients with bradycardia, heart block can
experience cardiac arrest upon administration
Beta blockers, cimetidine and quinidine can increase blood levels
of lidocaine
Midazolam (Versed) Therapeutic use / MOA correct answers
>> General anesthetic/ benzo or sedative
Enhances inhibitory effects of GABA
Used to provide sedation and induce amnesia
, Midazolam (Versed) Adverse effects correct answers >> Can
cause CNS depressant effects, anterograde amnesia (memory
loss), and cardiac/respiratory arrest
Midazolam (Versed) Administration & client education correct
answers >> IM, IV or PO
Give by IV bolus and titrate with additional doses for desired
depth of sedation
Midazolam (Versed) Contraindications/precautions/interactions
correct answers >> Caution those with neuromuscular, cardiac,
pulmonary or renal disorders
Pregnancy/delivery/lactation
Enhances CNS depressant effect of other CNS depressants
Methohexital (Brevital) Therapeutic use / MOA correct answers
>> Used for general anesthesia, causes CNS depression
Hypotension/resp. Depression
Atorvastatin Therapeutic use / MOA correct answers >>
Lowers the bad and increases the good cholesterol
Lower LDL, VLDL, and triglycerides. Increases HDL.
First line for hypercholesterolemia
Atorvastatin Adverse effects correct answers >> Cataracts,
rash, memory loss, HA, GI upset
Myopathy (muscle pain) occurs in 5-10% of pt
Can progress to rhabdomyolysis
