NREMT CARDIOLOGY: EXAM REVIEW QUESTIONS WITH
COMPLETE SOLUTIONS
1) The electrical disturbance that results in reversal of the normal direction of
ventricular depolarization is:
A) RBBB
B) LBBB
C) ectopic atrial pacemaker
D) atrial fibrillation -- Correct Answer ✔✔ B) LBBB
2) LBBB must have a widened QRS complex of which duration?
A) >30 ms
B) >60 ms
C) >90 ms
D) >120 ms -- Correct Answer ✔✔ D) >120 ms
3) An RSR' in V1 with a QS wave in V6 is an indicator of:
A) bifascicular block
B) hemiblock
C) LBBB
D) RBBB -- Correct Answer ✔✔ D) RBBB
4) What is the term for a markedly different manner of conduction from the normal
conduction of the cardiac muscle?
A) diffusion
B) aberration
C) convergence
D) divergence -- Correct Answer ✔✔ B) aberration
, 5) A QRS wave in V1 with an RSR' in V6 is an indicator of:
A) bifascicular block
B) hemiblock
C) LBBB
D) RBBB -- Correct Answer ✔✔ C) LBBB
6) You are dispatched to an overdose. When you arrive, you find a 30 y/o female that
has taken an unknown quantity of nortriptyline and Valium. She is slow to answer
questions and her speech is slurred. Her BP is 90/75, HR 138 bpm, RR 26/min. The
EKG shows sinus tachycardia with QRS complexes that measure 0.08 sec. What is
the best treatment for this patient?
A) Narcan 2 mg IVP
B) 2 g activated charcoal
C) 20 mL/kg NS
D) 1 mEq/kg bicarb -- Correct Answer ✔✔ C) 20 mL/kg NS
Bicarb not necessary in this patient since the QRS is not widened.
7) The most common cause of VF is which of the following?
A) PVCs
B) SVT
C) MI
D) a-fib -- Correct Answer ✔✔ C) MI
8) In which cardiac rhythm do the cells in the ventricular walls depolarize and
repolarize independently of the rest of the cardiac cells?
A) VT
B) SVT
C) VF
D) asystole -- Correct Answer ✔✔ C) VF
9) Ventricular standstill usually manifests as:
A) chest pain
B) diaphoresis
C) syncope
D) referred pain to the left arm -- Correct Answer ✔✔ C) syncope
