A 43-year-old woman is at the clinic for a routine examination. She reports that she has
had a breast lump in her right breast for years. Recently, it has begun to change in
consistency and is becoming harder. She reports that 5 years ago her physician
evaluated the lump and determined that it “was nothing to worry about.” The
examination validates the presence of a mass in the right upper outer quadrant at 1
o”clock, approximately 5 cm from the nipple. It is firm, mobile, and nontender, with
borders that are not well defined. The nurse replies:
a. “Because of the change in consistency of the lump, it should be further evaluated by a
physician.”
b. “The changes could be related to your menstrual cycles. Keep track of the changes in
the mass each month.”
c. “The lump is probably nothing to worry about because it has been present for years
and was determined to be noncancerous 5 years ago.”
d. “Because you are experiencing no pain and the size has not changed, you should
continue to monitor the lump and return to the clinic in 3 months.”
When listening to heart sounds, the nurse knows the valve closures that can be heard
best at the base of the heart are:
a. Mitral and tricuspid.
b. Tricuspid and aortic.
c. Aortic and pulmonic.
