During auscultation, you can limit your perceptual field best by:
a. asking patients to describe their symp-toms.
b. closing your eyes.
c. performing auscultation before percussion.
d. using an aneroid manometer.
B
By closing your eyes, your sense of hearing becomes more acute, and it increases your ability to isolate sounds. Asking patients to describe their symptoms does not assist in the technique of auscultation. The only time that auscultation occurs before percussion is in examination of the abdomen. Using an aneroid manometer does not assist in the technique of auscultation. During auscultation, the only equipment needed is the stethoscope.
