IBHRE CEPS FINAL EXAM WITH ALL
QUESTIONS AND ANSWERS
midazolam - ANSWER what is the common name for Versed
.04 mg/kg - ANSWER standard adult dose of atropine
half dose - ANSWER how much NPH insulin should a patient be
administered prior to an EP study? (they are fasting think about blood
sugar)
4-8 weeks - ANSWER What is the elimination half life of amiodarone?
4 half lives - ANSWER how long should an anti arrhythmic drug be
discontinued prior to EP study?
sodium channel - ANSWER what do class I drugs primarily affect?
slope of phase 0 (depolarization speed) - ANSWER what do class 1
drugs effect on sodium channels primarily do?
Class 1A drugs - ANSWER slow conduction velocity and increase
refractoriness
Class 1B drugs - ANSWER drugs that shorten refractory periods
Class 1C drugs - ANSWER pronounced depressants on conduction
velocity
class II drugs - ANSWER What class antiarrhythmic are beta blockers
Class II Drugs (Beta Blockers) - ANSWER Prevent
catecholamine-mediated action on the heart, blocks sympathetic
nervous system cardiac effects (no effect on AP, decreases
sympathetic tone)
`class III drugs - ANSWER increase AP duration by increasing
refractoriness but do not affect conduction velocity
, class IV drugs - ANSWER calcium channel blockers (primarily
affecting SA and AV nodes)
Class V drugs - ANSWER digitalis agents that are used to increase
parasympathetic activity
Class IA drug examples - ANSWER procainamide, disopyrimidine,
quinidine
Class IB drug examples - ANSWER Lidocaine Mexiletine
Class IC drug examples - ANSWER Flecainide, Propafenone,
Encainide
Class II antiarrhythmic drug examples (beta blockers) - ANSWER
propanolol, metoprolol, atenolol, esmolol
class III drug examples - ANSWER amiodarone, ibutilide, sotolol,
dofetilide
Class IV drug examples - ANSWER Verapamil, Diltiazem
1:1 (10 mg/1000 units) - ANSWER what is the ratio that heparin and
protamine counteract eachother?
2.0-3.0 - ANSWER INR needed for heparinizing a left sided case
prothrombin to thrombin - ANSWER what part of the coagulation
cascade does heparin block?
after gaining venous access - ANSWER when is heparin usually
administered during a case requiring a transeptal puncture?
hypotension - ANSWER what can happen if procainamide is
administered too quickly?
no known reversal agents - ANSWER why discontinue Xarelto and
