Changes in the Breast - Answer -Enlargement of size and increased sensitivity
-Skin pigmentation around the areola darkens with the advancement of pregnancy and
with increased production of estrogen
Nipples become more erect and sensitive, colostrum may be present in third trimester

How to Palpate Fundus - Answer Position woman with knees flexed and head flat. Just
below umbilicus, cup hand and press it firmly against the woman's abdomen. At same
time, stabilize uterus at symphysis with opposite hand.
If fundus is firm (and bladder is empty), with uterus in midline, measure its position
relative to umbilicus. Measure how many fingerbreadths or cm fit between the umbilicus
and top of fundus.
If fundus is not firm, massage it gently to contract and expel any clots before measuring
distance from umbilicus.
Abdominal Girth Assessing Uterine Contractions By Palpation - Answer Mild: Slightly
tense fundus that is easily indented with fingertips (like pressing a finger to the tip of the
nose)
Moderate: Firm fundus that is resistant to indentation with fingertips (like pressing a
finger to the chin)
Good: Rigid board-like fundus that is almost impossible to indent with fingertips-feels
like pressing a finger to the forehead
