IBHRE Prep Exam UPDATED ACTUAL
Exam Questions and CORRECT Answers
Voltage - CORRECT ANSWER - Constant force or push that causes electrons to move
through a circuit. Represented "V"
Current - CORRECT ANSWER - The flow of electrons in a completed circuit.
Represented "I"
Impedance - CORRECT ANSWER - The opposition to current flow.
Represented in "R"
BPM to Hertz - CORRECT ANSWER - 60bpm=1hz
1bpm=1/60hz
100bpm=1.67hz
1.67x100=100bpm.
Capacitor - CORRECT ANSWER - Stores electrical charge
Reed Switch - CORRECT ANSWER - Switch activated by a magnet causing
asynchronous pacing now a solid state magnet detector.
Diode - CORRECT ANSWER - Restricts current flow to 1 direction
Resister - CORRECT ANSWER - Restricts current flow
Rectifier - CORRECT ANSWER - Converts a biphasic signal to all positive or all
negative.
, Transistor - CORRECT ANSWER - Semiconductor used for switching and application.
Class I Indication for Implant PM - CORRECT ANSWER - Benefits outweight the risk
Prodedure treatment should be performed/administered
Class IIa - CORRECT ANSWER - Benefits outweight the risk
Additional studies w/focused objectives needed.
It is reasonable to perform procedure and or administer treatment.
Class IIb - CORRECT ANSWER - Benefit is >risk
Addt'l studies w/broad objective needed; addt'l registry data would be helpful.
Procedure/treatment MAY BE CONSIDERED.
Class III - CORRECT ANSWER - Risk>benefit.
Procedure/treatment should NOT BE performed/administer SINCE IT IS NOT HELPFU AND
MAY BE HARMFUL.
Recommendations for permanent pacing in SND. Class I - CORRECT ANSWER -
Mandatory: Symptomatic bradycardia with frequent sinus pauses.
Symptomatic
Required Rx's causes symptomatic bradycardia (eg. pt. is HTN & on a BB).
Class IIa - CORRECT ANSWER - Reasonable: Permanent PM is reasonable for
HR<40bpm. w/clear association between significant symptoms consistent w/bradycardia and the
actual presence of bradycardia has not been documented (ie. lack of ECG or ambulatory
monitoring) Reasonable for syncope of unexplained origin.
