NUSCTX CHAPTER 9 EXAM
QUESTIONS WITH CORRECT
ANSWERS
The nurse is performing a contraction stress test (CST) and notes no late
decelerations. How should the nurse interpret this test result?
1 Negative CST
2 Positive CST
3 Suspicious CST
4 Equivocal CST - ANSWER-1 Negative CST
A negative CST describes a fetal heart rate response to contractions with no
decelerations. A positive CST describes a fetal heart rate deceleration with a
minimum of 50% of the contractions. A suspicious or equivocal response describes
intermittent late decelerations or a sudden decrease in fetal heart rate that quickly
returns to the baseline.
The levels of which hormones and proteins are measured in a triple screen maternal
serum test? Select all that apply.
1
Human chorionic gonadotropin (hCG)
2
Alpha-fetoprotein (AFP)
3
Unconjugated estriol (uE3)
4
Hemoglobin
5
Bilirubin - ANSWER-1,2,3
The hormones and proteins that are measured in a triple screen are hCG, AFP, and
uE3. Hemoglobin and bilirubin are not measured in a triple screen.
How is percutaneous umbilical blood sampling (PUBS) performed?
1
A long needle is inserted through the abdomen into the umbilical vein.
2
A transducer probe is inserted into the vagina.
3
A Doppler ultrasound transducer is placed on the abdomen.
4
A long needle is inserted through the abdomen into the amniotic sac. - ANSWER-1 A
long needle is inserted through the abdomen into the umbilical vein.
PUBS is performed by inserting a long needle through the abdomen into the
umbilical vein. Transvaginal ultrasound is performed by inserting a transducer probe
into the vagina. A transabdominal ultrasound transducer is performed by placing a
,Doppler ultrasound on the abdomen. An amniocentesis is performed by inserting a
long needle through the abdomen into the amniotic sac.
What does a nurse providing care for the antepartum woman need to understand
about the contraction stress test (CST)?
1
It sometimes uses vibroacoustic stimulation.
2
It is an invasive test; however, contractions are stimulated.
3
It is considered negative if no late decelerations are observed with the contractions.
4
It is more effective than nonstress test (NST) if the membranes have already been
ruptured. - ANSWER-3 It is considered negative if no late decelerations are
observed with the contractions.
No late decelerations indicate a negative CST. Vibroacoustic stimulation is
sometimes used with NST. CST is invasive if stimulation is by IV oxytocin but not if
by nipple stimulation. CST is contraindicated if the membranes have ruptured.
The nurse is caring for four patients, all at 38 weeks of gestation. Which patient's
nonstress test (NST) is most likely to show altered fetal movement?
1
The patient who ate eggs and grits prior to the NST
2
The patient who is taking methadone daily
3
The patient who takes ferrous sulfate daily
4
The patient who is pregnant with twins - ANSWER-2 The patient who is taking
methadone daily
Ingestion of methadone can alter fetal movement. Intake of eggs and grits, ingestion
of ferrous sulfate, and the presence of twins should not cause altered fetal
movement.
While caring for a patient receiving a nonstress test, the nurse does not observe
accelerations in the fetal heart rate after 30 minutes of FHR monitoring. What
intervention might the nurse perform in order to elicit FHR accelerations?
1
Place the patient in a lateral position.
2
Help the patient to elevate her legs.
3
Administer oxygen by face mask.
4
Provide vibroacoustic stimulation. - ANSWER-4 Provide vibroacoustic stimulation
If fetal heart rate accelerations do not occur after 20 to 30 minutes of continuous
FHR monitoring, the nurse can use vibroacoustic stimulation. The patient in labor is
, usually placed in a lateral or semi-Fowler's position to prevent umbilical cord
prolapse. Often, the patient is assisted to turn to the left side. The nurse administers
oxygen via a nonrebreather face mask in case of fetal hypoxemia.
A nurse is caring for a patient who is scheduled for a biophysical profile. Which
criteria are included in the scoring of a biophysical profile? Select all that apply.
1
Fetal tone
2
Nonstress test (NST)
3
Contraction stress test (CST)
4
Gross body movements
5
Amniotic fluid volume
6
Fetal breathing movements - ANSWER-1,2,4,5,6
The biophysical profile includes the fetal tone, NST, gross body movement, amniotic
fluid volume, and fetal breathing movements. A CST is not included in the scoring for
a biophysical profile.
What is the preferred gestational age to have chorionic villi sampling (CVS)
performed?
1
6 weeks
2
11 weeks
3
20 weeks
4
30 weeks - ANSWER-2 11 weeks
The preferred time to have CVS performed is between 10 and 13 weeks of gestation;
11 weeks falls into this range. Six weeks of gestation is too early for CVS to be
performed; 20 and 30 weeks of gestation are too late for CVS to be performed.
What is a disadvantage of an amniocentesis?
1
It cannot be performed until 36 weeks of gestation.
2
Test results take at least 10 days to obtain.
3
It does not determine fetal lung maturity.
4
It cannot be used to identify genetic abnormalities. - ANSWER-2 Test results can
take at least 10 days to obtain
