What this exam covers
5 real sample questions
Which landmark identifies the standard V4 position?
A. Fourth intercostal space at the left midaxillary line.
B. Fifth intercostal space at the left anterior axillary line.
C. Fourth intercostal space at the left sternal border.
D. Fifth intercostal space at the left midclavicular line.
Show answer and reasoning

Correct answer: D. Fifth intercostal space at the left midclavicular line.

  • A: Fourth intercostal space at the left midaxillary line is incorrect. This is neither the correct interspace nor line for V4.
  • B: Fifth intercostal space at the left anterior axillary line is incorrect. The anterior axillary line at V4 level is the V5 location.
  • C: Fourth intercostal space at the left sternal border is incorrect. The fourth intercostal space at the left sternal border is V2.
Source: NHA CET Exam Content Outline; objective: v4-placement
V4 is correctly placed. Which site is correct for V5?
A. Use the V4 level at the left anterior axillary line.
B. One interspace below V4 on the left anterior axillary line.
C. At the same horizontal level as V4 on the left midaxillary line.
D. Halfway between V1 and V2.
Show answer and reasoning

Correct answer: A. Use the V4 level at the left anterior axillary line.

  • B: One interspace below V4 on the left anterior axillary line is incorrect. Dropping an interspace makes V5 too low.
  • C: At the same horizontal level as V4 on the left midaxillary line is incorrect. The midaxillary location at this level is V6.
  • D: Halfway between V1 and V2 is incorrect. The midpoint between V1 and V2 is not a standard V5 landmark.
Source: NHA CET Exam Content Outline; objective: v5-placement
Where should V6 be placed after V4 and V5 are correctly positioned?
A. At the left posterior axillary line one interspace below V5.
B. Use the left midaxillary line at the level of V4 and V5.
C. At the right midaxillary line level with V4.
D. At the left sternal border in the fifth intercostal space.
Show answer and reasoning

Correct answer: B. Use the left midaxillary line at the level of V4 and V5.

  • A: At the left posterior axillary line one interspace below V5 is incorrect. V6 is not posterior to the midaxillary line or below V5.
  • C: At the right midaxillary line level with V4 is incorrect. V6 is a left-sided precordial electrode.
  • D: At the left sternal border in the fifth intercostal space is incorrect. The left sternal border is too medial for V6.

A stable adult tracing has a rate of 52 beats/min, regular R-to-R intervals, and one normal-appearing P wave before every QRS. What pattern should be reported?
A. Atrial fibrillation
B. Ventricular tachycardia
C. Atrial flutter
D. Sinus bradycardia pattern
Show answer and reasoning

Correct answer: D. Sinus bradycardia pattern

  • A: Atrial fibrillation is incorrect. Atrial fibrillation lacks consistent P waves and is irregularly irregular.
  • B: Ventricular tachycardia is incorrect. Ventricular tachycardia is a fast ventricular rhythm, not a regular sinus pattern at 52.
  • C: Atrial flutter is incorrect. Atrial flutter has rapid flutter waves rather than one sinus P before each QRS.
Source: NHA CET Exam Content Outline; objective: sinus-bradycardia
A regular tracing shows a rate of 118 beats/min, uniform P waves before every narrow QRS, and consistent PR intervals. Which pattern best fits?
A. Sinus tachycardia pattern
B. Atrial fibrillation
C. Complete heart block
D. Ventricular fibrillation
Show answer and reasoning

Correct answer: A. Sinus tachycardia pattern

  • B: Atrial fibrillation is incorrect. Atrial fibrillation is irregularly irregular and lacks discernible consistent P waves.
  • C: Complete heart block is incorrect. Complete heart block shows atrial and ventricular activity without a stable one-to-one relationship.
  • D: Ventricular fibrillation is incorrect. Ventricular fibrillation is chaotic and has no organized P-QRS sequence.
