200 Comprehensive Exam Questions with Answers and Rationales



SECTION 1: FUNDAMENTAL MEASUREMENTS & ANATOMY (Questions 1-40)



QUESTION 1:
On standard EKG paper, what is the duration (in seconds) of one small box (1 mm)?

A. 0.20 seconds
B. 0.04 seconds
C. 0.12 seconds
D. 0.08 seconds

ANSWER:
B. 0.04 seconds

RATIONALE:
Standard EKG paper runs at 25 mm/second. Each small box (1 mm) represents 0.04 seconds (1/25 =
0.04). Five small boxes equal one large box at 0.20 seconds. This measurement is fundamental for
calculating all EKG intervals and heart rates .



QUESTION 2:
The normal PR interval duration is:

A. 0.04-0.10 seconds
B. 0.08-0.11 seconds
C. 0.12-0.20 seconds
D. 0.20-0.30 seconds

ANSWER:
C. 0.12-0.20 seconds

RATIONALE:
The PR interval measures from the beginning of the P wave to the beginning of the QRS complex.
Normal duration is 0.12-0.20 seconds (3-5 small boxes). A PR interval greater than 0.20 seconds
indicates first-degree AV block, while less than 0.12 seconds suggests a junctional rhythm or pre-
excitation syndrome .



QUESTION 3:
Which structure in the heart's conduction system is known as the "pacemaker" because it typically
initiates the electrical impulse at a rate of 60-100 times per minute?

A. Atrioventricular (AV) node
B. Bundle of His
