Answer to Question 1

ANS: B
Auscultation of breath sounds should not be limited to only four locations. Sounds produced by the valves may be heard all over the precordium. The stethoscope should be inched in a rough Z pattern from the base of the heart across and down, then over to the apex; or, starting at the apex, it should be slowly worked up (see Figure 19-22). Listening selectively to one sound at a time is best.

Answer to Question 2

ANS: C
Numerous comparison studies have shown that the percussed cardiac border correlates only moderately with the true cardiac border. Percussion is of limited usefulness with the female breast tissue, in a person who is obese, or in a person with a muscular chest wall. Chest x-ray images or echocardiographic examinations are significantly more accurate in detecting heart enlargement.
