EP IBHRE COMPREHENSIVE TEST
SCRIPT 2026 QUESTIONS WITH
SOLUTIONS 100% CORRECT.
◍ for maximum electrical safety the ECG monitored patient should be
___ and the monitor chassis should be ___ or nonconductive. Answer-
ungrounded, grounded
◍ in the ICU when recording an intracardiac ECG from a pacing
electrode or a pericardiocentesis needle in the heart it is safest to.
Answer- use a battery powered monitor
◍ when you plug in an electric instrument you are alarmed when sparks
fly from the wall outlet. the most likely electrical safety problem is a.
Answer- machine off-on swtich was left turned on
◍ the prefix centi corresponds to. Answer- 1/100
◍ which prefix is correctly arranged from smallest to largest. Answer-
nano, micro, milli, centi
◍ convert 30kg into pounds. Answer- 66
, ◍ 100 degrees fahrenheit equals. Answer- 38 degrees C
◍ a PR interval measures 4mm long on an ECG strip which was run at
paper speed 25mm/s. how long is the PR interval. Answer- 160msec
◍ in EP the forumula for calculating HR is. Answer-
60,000msec/min/time period in milliseconds
◍ calculate the HR if R-R is 920msec. Answer- 65bpm
HR = 60/R-R
◍ when the heart rate is insensitive to stimuli and cannot be depolarized
by stimulation (such as pacing) is it said to be. Answer- refractory
◍ purkinje and ventricular cells have their own automaticity and
intrinsic rate. these lower pacemaker rates are usually suppressed as long
as. Answer- the SA node rate is fast enough
◍ sympathetic nervous stimulation of the heart primarily affects the HR
by altering what phase of the SA node action potential. Answer- phase 4
◍ which of the following below is not one of the 3 things which change
the rate (automaticity) of automatic cells. Answer- unidirectional block
