N144 Exam 2 Practice Questions With
Complete Solutions
Sally comes in for her first prenatal examination. This is her first
|| || || || || || || || || || || ||
child. She asks you (the nurse), "How does my baby get air inside
|| || || || || || || || || || || || ||
my uterus?" The correct response is:
|| || || || ||
a. "The baby's lungs work in utero to exchange oxygen and carbon
|| || || || || || || || || || || ||
dioxide."
b. "The baby absorbs oxygen from your blood system."
|| || || || || || || ||
c. "The placenta provides oxygen to the baby and excretes carbon
|| || || || || || || || || || ||
dioxide into your bloodstream."
|| || ||
d. "The placenta delivers oxygen-rich blood through the umbilical
|| || || || || || || || ||
artery to the baby's abdomen."
|| || || ||
c. "The placenta provides oxygen to the baby and excretes carbon
|| || || || || || || || || || ||
dioxide into your bloodstream."
|| || ||
,The placenta functions by supplying oxygen and excreting carbon
|| || || || || || || || ||
dioxide to the maternal bloodstream. The fetal lungs do not function
|| || || || || || || || || ||
for respiratory gas exchange in utero. The baby does not simply
|| || || || || || || || || || || ||
absorb oxygen from a woman's blood system. Blood and gas
|| || || || || || || || || ||
transport occur through the placenta. The placenta delivers oxygen-
|| || || || || || || ||
rich blood through the umbilical vein and not the artery.
|| || || || || || || || ||
As relates to the structure and function of the placenta, the
|| || || || || || || || || || ||
maternity nurse should be aware that: || || || || ||
a. as the placenta widens, it gradually thins to allow easier passage
|| || || || || || || || || || || ||
of air and nutrients.
|| || ||
b. as one of its early functions, the placenta acts as an endocrine
|| || || || || || || || || || || || ||
gland.
c. the placenta is able to keep out most potentially toxic substances
|| || || || || || || || || || || ||
such as cigarette smoke to which the mother is exposed.
|| || || || || || || || ||
d. optimal blood circulation is achieved through the placenta when
|| || || || || || || || || ||
the woman is lying on her back or standing.
|| || || || || || || ||
,b. as one of its early functions, the placenta acts as an endocrine
|| || || || || || || || || || || || ||
gland.
The placenta produces four hormones necessary to maintain the
|| || || || || || || || ||
pregnancy. The placenta widens until week 20 and continues to
|| || || || || || || || || ||
grow thicker. Toxic substances such as nicotine and carbon monoxide
|| || || || || || || || ||
readily cross the placenta into the fetus. Optimal circulation occurs
|| || || || || || || || || || ||
when the woman is lying on her side.
|| || || || || || ||
The nurse caring for a pregnant patient knows that her health
|| || || || || || || || || || ||
teaching regarding fetal circulation has been effective when the
|| || || || || || || || ||
patient reports that she has been sleeping:
|| || || || || ||
a. in a side-lying position.
|| || || ||
b. on her back with a pillow under her knees.
|| || || || || || || || ||
c. with the head of the bed elevated.
|| || || || || || ||
d. on her abdomen.
|| || ||
, a. in a side-lying position.
|| || || ||
Optimal circulation is achieved when the woman is lying at rest on
|| || || || || || || || || || || ||
her side. Decreased uterine circulation may lead to intrauterine
|| || || || || || || || ||
growth restriction. Previously it was believed that the left lateral
|| || || || || || || || || ||
position promoted maternal cardiac output, enhancing blood flow to
|| || || || || || || ||
the fetus. However, it is now known that the side-lying position
|| || || || || || || || || || || ||
enhances uteroplacental blood flow. If a woman lies on her back
|| || || || || || || || || || ||
with the pressure of the uterus compressing the vena cava, blood
|| || || || || || || || || || ||
return to the right atrium is diminished. Although having the head
|| || || || || || || || || || ||
of the bed elevated is recommended and ideal for later in
|| || || || || || || || || || ||
pregnancy, the woman still must maintain a lateral tilt to the pelvis
|| || || || || || || || || || || ||
to avoid compression of the vena cava. Many women find lying on
|| || || || || || || || || || || ||
her abdomen uncomfortable as pregnancy advances. Side-lying is the
|| || || || || || || ||
ideal position to promote blood flow to the fetus.
|| || || || || || || || ||
The placenta allows exchange of oxygen, nutrients, and waste
|| || || || || || || || ||
products between the mother and fetus by:
|| || || || || ||
a. contact between maternal blood and fetal capillaries within the
|| || || || || || || || || ||
chorionic villi. ||
