IBHRE CEPS TROUBLE QUESTIONS EXAM
SCRIPT 2026 FULL SOLUTION PRACTICE
◉ .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?
