1)
Where is the point of maximal impulse (PMI) normally located?
A. Second intercostal space, right sternal border
B. Second intercostal space, left sternal border
C. Fifth intercostal space, left midclavicular line
D. Fourth intercostal space, left sternal border
Answer: C. Fifth intercostal space, left midclavicular line
Rationale: The PMI (apical impulse) is normally located at the fifth intercostal space at the left
midclavicular line, representing the apex of the left ventricle.
2)
What does the S1 heart sound represent?
A. Aortic and pulmonic valve closure
B. Mitral and tricuspid valve closure
C. Ventricular filling
D. Atrial contraction
Answer: B. Mitral and tricuspid valve closure
, Rationale: S1 ("lub") represents the closure of the mitral and tricuspid valves at the beginning of
ventricular systole.
3)
Which pulse site is most commonly used for assessing circulation to the lower extremities?
A. Femoral
B. Popliteal
C. Dorsalis pedis
D. Posterior tibial
Answer: C. Dorsalis pedis
Rationale: The dorsalis pedis pulse is most commonly assessed to evaluate circulation to the
lower extremities, though posterior tibial pulse is also important.
4)
What does the S2 heart sound represent?
A. Mitral and tricuspid valve closure
B. Aortic and pulmonic valve closure
C. Ventricular filling
D. Atrial contraction
Answer: B. Aortic and pulmonic valve closure
Rationale: S2 ("dub") represents the closure of the aortic and pulmonic valves at the end of
ventricular systole.
