8. The nurse is preparing to use a stethoscope for auscultation.
Which statement is true regarding the diaphragm of the
stethoscope? The diaphragm:
a. is used to listen for high-pitched sounds.
b. is used to listen for low-pitched sounds.
c. should be held lightly against the person's skin to block out
low-pitched sounds.
d. should be held lightly against the person's skin to listen for
extra heart sounds and murmurs.
ANS: A
The diaphragm of the stethoscope is best for listening to high-
pitched sounds such as breath, bowel, and normal heart sounds.
It should be held firmly against the person's skin, firmly enough
to leave a ring. The bell of the stethoscope is best for soft, low-
pitched sounds such as extra heart sounds or murmurs.

10. An examiner is using an ophthalmoscope to examine a
patient's eyes. The patient has astigmatism and is nearsighted.
The use of which of these techniques would indicate that the
examination is being performed correctly?
a. Using the large full circle of light when assessing pupils that
are not dilated

compensate for astigmatism
c. Using the grid on the lens aperture dial to visualize the
external structures of the eye
d. Rotating the lens selector dial to bring the object into focus
ANS: D
The ophthalmoscope is used to examine the internal eye
structures. It can compensate for nearsightedness or
farsightedness, but it will not correct for astigmatism. The grid is
