OB Exam 3 Practice Questions With
Correct Answers
Your pregnant patient is in her first trimester and is scheduled for an
| | | | | | | | | | | | |
abdominal ultrasound. When explaining the rationale for early
| | | | | | | |
pregnancy ultrasound, the best response is:
| | | | | |
a. "The test will help to determine the baby's position."
| | | | | | | | |
b. "The test will help to determine how many weeks you are pregnant."
| | | | | | | | | | | |
c. "The test will help to determine if your baby is growing
| | | | | | | | | | | |
appropriately."
d. "The test will help to determine if you have a boy or girl." - CORRECT
| | | | | | | | | | | | | | | |
ANSWER✔✔-b. Fetal growth and size are fairly consistent during the | | | | | | | | | |
first trimester and are a reliable indicator of the weeks of gestation.
| | | | | | | | | | |
Your pregnant patient is having maternal alpha-fetoprotein (AFP)
| | | | | | | |
screening. She does not understand how a test on her blood can
| | | | | | | | | | | |
indicate a birth defect in the fetus. The best reply by the nurse is:
| | | | | | | | | | | | |
a. "We have done this test for a long time."
| | | | | | | | |
b. "If babies have a neural tube defect, alpha-fetoprotein leaks out of
| | | | | | | | | | | |
the fetus and is absorbed into your blood, causing your level to rise. This
| | | | | | | | | | | | |
serum blood test detects that rise."
| | | | | |
,c. "Neural tube defects are a genetic anomaly, and we examine the
| | | | | | | | | | | |
amount of alpha-fetoprotein in your DNA."
| | | | |
d. "If babies have a neural tube defect, this results in a decrease in your
| | | | | | | | | | | | | | |
level of alpha-fetoprotein." - CORRECT ANSWER✔✔-b. When a neural
| | | | | | | | |
tube defect is present, AFP is absorbed in the maternal circulation,
| | | | | | | | | | |
resulting in a rise in the maternal AFP level.
| | | | | | | |
The primary complications of amniocentesis are:
| | | | |
a. Damage to fetal organs
| | | |
b. Puncture of umbilical cord
| | | |
c. Maternal pain
| |
d. Infection - CORRECT ANSWER✔✔-d. Amniocentesis involves insertion
| | | | | | |
of a needle into the amniotic sac, and infection is the primary
| | | | | | | | | | | | |
complication.
Your patient is 34 weeks pregnant and during a regular prenatal visit
| | | | | | | | | | | |
tells you she does not understand how to do "kick counts." The best
| | | | | | | | | | | | |
response by the nurse would be to explain:
| | | | | | |
a. "Here is an information sheet on how to do kick counts."
| | | | | | | | | | |
b. "It is not important to do kick counts because you have a low-risk
| | | | | | | | | | | | | |
pregnancy."
c. "Fetal kick counts are not a reliable indicator of fetal well-being in the
| | | | | | | | | | | | | |
third trimester." |
,d. "Fetal movements are an indicator of fetal well-being. You should
| | | | | | | | | | |
count twice a day, and you should feel 10 fetal movements in 2 hours." -
| | | | | | | | | | | | | | |
CORRECT ANSWER✔✔-d. This response provides the patient with
| | | | | | | |
information on how to do kick counts and the rationale for doing kick
| | | | | | | | | | | | |
counts and criteria for normal fetal movement.
| | | | | |
Your patient is a 37-year-old pregnant woman who is 5 weeks pregnant
| | | | | | | | | | | |
and is considering genetic testing. During your discussion, the woman
| | | | | | | | | |
asks the nurse what the advantages of chorionic villus sampling (CVS)
| | | | | | | | | | |
are over amniocentesis. The best response is:
| | | | | |
a. "You will need anesthesia for amniocentesis, but not for CVS."
| | | | | | | | | |
b. "CVS is a faster procedure."
| | | | |
c. "CVS provides more detailed information than amniocentesis."
| | | | | | |
d. "CVS can be done earlier in your pregnancy, and the results are
| | | | | | | | | | | | |
available more quickly." - CORRECT ANSWER✔✔-d. CVS can be done
| | | | | | | | | |
earlier in gestation | |
The clinic nurse meets with Rebecca, a 30-year-old woman who is
| | | | | | | | | | |
experiencing her first pregnancy. Rebecca's quadruple marker screen | | | | | | | |
result is positive at 17 weeks' gestation. The nurse explains that Rebecca
| | | | | | | | | | |
needs a referral to:
| | | |
a. A genetics counselor/specialist
| | |
b. An obstetrician
| |
c. A gynecologist
| |
, d. A social worker - CORRECT ANSWER✔✔-a. All women should be
| | | | | | | | | | |
offered screening with maternal serum markers. The Triple Marker
| | | | | | | | |
screen and the Quadruple Marker screen test for the presence of alpha-
| | | | | | | | | | |
fetoprotein (AFP), estradiol, human chorionic gonadotropin (hCG), and
| | | | | | | |
other markers. These tests screen for potential neural tube defects,
| | | | | | | | | |
Down syndrome, and Trisomy 18. If the screen is positive, the woman
| | | | | | | | | | | |
should be referred to a genetics specialist for counseling, and further
| | | | | | | | | | |
testing, such as chorionic villus sampling (CVS) or amniocentesis, should
| | | | | | | | | |
be performed.
|
A 37-year-old woman who is 17 weeks pregnant has had an
| | | | | | | | | | |
amniocentesis. Before discharge, the nurse teaches the woman to call | | | | | | | | | |
her doctor if she experiences which of the following side effects?
| | | | | | | | | |
a. Pain at the puncture site
| | | | |
b. Macular rash on the abdomen
| | | | |
c. Decrease in urinary output
| | | |
d. Cramping of the uterus - CORRECT ANSWER✔✔-d. The woman
| | | | | | | | | |
should report any uterine cramping. Although rare, amniocentesis could
| | | | | | | |
stimulate preterm labor.
| | |
A laboratory report indicates the L/S ratio (lecithin/sphingomyelin)
| | | | | | | |
results from an amniocentesis of a gravid patient with preeclampsia are
| | | | | | | | | | |
2:1. The nurse interprets the result as which of the following?
| | | | | | | | | |
a. The baby's lung fields are mature.
| | | | | |
b. The mother is high risk for hemorrhage.
| | | | | | |
