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."

a. in a side lying position
b. on her back with a pillow under her knees
c. wit the head of the bed elevated
d. on her abdomen.
8. When nurses help their expectant mothers assess daily fetal movement counts, they should be aware that
a. alcohol or cigarette smoke can irritate the fetus into greater activity.
b. "kick counts" should be taken every half hour and averaged every 6 hours, with every other 6-hr stretch off.
, c. the fetal alarm signal should go off when fetal movements stop entirely for 12 hours.
d. obese mothers familiar with their bodies can assess fetal movement as well as average-size women.
9. Nurses should be aware that the biophysical profile (BPP)
a. is an accurate indicator of impending fetal death
b. is a compilation of health risk factors of the mother during the later stages of pregnancy
c. consists of a doppler blood flow analysis and an amniotic fluid index
d. involves an invasive form of ultrasound examination
10. Compared with contraction stress test (CST), nonstress test (NST) for antepartum fetal assessment
• a. has no known contraindications
b. has fewer false-positive results
c. is more sensitive in detecting fetal compromise
d. is slightly more expensive
11. A pregnant woman's biophysical profile score is 8. She asks the nurse to explain the results. The nurse's
best response is
• a. "The test results are within normal limits."
b. Immediate delivery by cesarean birth is being considered."
c. Further testing will be performed to determine the meaning of this score."
d. An obstetric specialist will evaluate the results of this profile and, within the next week, will inform you of your
options regarding delivery

of 15 beats/min or more occur with fetal movement in a 20-minute period is
a. nonreactive
b. positive
c. negative
d. reactive
