CPAN/CAPA EXAM QUESTIONS AND
ANSWERS
crackles - Correct Answers -during inspiration, fluid and exudate in terminal bronchioles
or alveoli (fine or coarse)
wheeze - Correct Answers -partial airway obstruction or narrowing of airways
rhonchi - Correct Answers -snoring, rattling, rumbling- expiration
pleural friction rub - Correct Answers -inflammation in pleural lining, rough, creaking,
grating
pseudocholinesterase - Correct Answers -serine hydrolase (enzyme family) capable of
hydrolyzing esters (breaking down with H20) including succinycholine, mivacurium,
acetylcholine, and ester type local anesthesia
succinylcholine - Correct Answers -the only depolarizing muscle relaxant, mimics the
acetylcholine, Anectine, broken down by pseudocholinesterase, can cause bradycardia,
rapid and short acting, onset 30-60 sec, offset 3-5min, hepatorenal independent, causes
histamine release, trigger for malignant hyperthermia, bradycardia, hyperkalemia,
increase in intraocular and IP
mivacurium - Correct Answers -nondepolarizing muscle relaxant that competes with
acetycholine
atracurium - Correct Answers -nonpolarizing muscle relaxant, metabolized by Hoffman
elimination and by nonspecific plasma esterases, intermediate acting, onset 305 min,
duration 20-35 min
rocuronium - Correct Answers -nondepolarizing muscle relaxant eliminated via the liver,
rapid onset 1-1.5min, duration 12-30min
