Ob Antepartum Care Nclex Questions Correct
Answers Latest Update

During an examination, a client who's 32 weeks' pregnant becomes dizzy, light-
headed, and pale while supine. What should the nurse do first?

1. Listen to fetal heart tones.

2. Take the client's blood pressure

3. Ask the client to breathe deeply

4. Turn the client on her left side. -ANS>4. Turn the client on her left side.

As the enlarging uterus increases pressure on the inferior vena cava, it
compromises venous return, which can cause dizziness, light-headedness, and
pallor when the client is supine. The nurse can relieve these symptoms by turning
the client on her left side, which relieves pressure on the vena cava and restores
venous return. Although they're valuable assessments, fetal heart tone and
maternal blood pressure measurements don't correct the problem. Because deep
breathing has no effect on venous return, it can't relieve the client's symptoms.

A nurse is reinforcing the instructions given to a client in her education plan about
the signs of labor. The nurse determines that the client has an accurate
understanding of the instructions when which statement is made by the client?

1. "False contractions are regular"

2. "False contractions intensify with walking."

,3. "False contractions usually occur in the abdomen."

4. "False contractions move from the back to the front of the abdomen." -ANS>3.
"False contractions usually occur in the abdomen."

False labor contractions are usually felt in the abdomen, are irregular, and are
typically relieved by walking. True labor contractions move from the back to the
front of the abdomen, are regular, and aren't relieved by walking.

Antepartum testing from a client pregnant with twins reveals a twin-to-twin
transfusion syndrome. The nurse is assisting with development of a plan of care.
Which condition will the nurse likely provide interventions for?

1. Anemia

2. Oligohydramnios

3. Polycythemia

4. Small size -ANS>3. Polycythemia

the recipient twin in twin-to-twin transfusion syndrome (also known as twin-twin
transfusion syndrome) is transfused by the other twin. The recipient twin then
becomes polycythemic and commonly as heart failure due to circulatory overload.
The donor twin becomes anemic. The recipient twin has polyhydramnios, not
oligohydramnios. The recipient twin is usually large, whereas the donor twin is
usually small in size.

,A pregnant client who reports painless vaginal bleeding at 28 weeks' gestation is
diagnosed with placenta previa, in which the placental edge reaches the internal
os. The nurse would suspect the client has which type of placenta previa?

1. Low-lying placenta previa

2. Marginal placenta previa

3. Partial placenta previa

4. Total placenta previa -ANS>2. Marginal placenta previa

A marginal placenta previa is characterized by implantation of the placenta in the
margin of the cervical os, not covering the os. A low-lying placenta is implanted in
the lower uterine segment but doesn't reach the cervical os. A partial placenta
previa is the partial occlusion of the cervial os by the placenta. The internal cervical
os is completely covered by the placenta in a total placenta previa.

A client is diagnosed with placenta previa at 28 weeks' gestation. Which procedure
should the nurse prepare the client for?

1. Stat culture and sensitivity

2. Antenatal steroids after 34 weeks' gestation

3. Ultrasound examination every 2-3 weeks

4. Scheduled birth of the fetus before fetal maturity -ANS>3. Ultrasound
examination every 2-3 weeks

, Fetal surveillance through ultrasound examination every 2-3 weeks is indicated to
evaluate fetal growth, amniotic fluid, and placental location in clients with
placenta previa being expectantly managed. A stat culture and sensitivity would be
done for severe bleeding, or maternal or fetal distress, and isn't part of expectant
management. Antenatal steroids may be given to clients between 26-32 weeks'
gestation to enhance fetal lung maturity. In a hemodynamically stable mother,
birth of the fetus should be delayed until fetal lung maturity is attained.

A client with painless vaginal bleeding is suspected of having placenta previa. The
nurse will assist in preparing the client for which procedure?

1. Amniocentesis

2. Speculum examination

3. External fetal monitoring

4. Ultrasound -ANS>4. Ultrasound

When the mother and fetus are stabilized, ultrasound evaluation of the placenta
should be done to determine the cause of bleeding. Amniocentesis is
contraindicated in placenta previa. A digital or speculum examination shouldn't be
done, as this may lead to severe bleeding or hemorrhage. External fetal monitoring
won't detect a placenta previa, although it will detect fetal distress, which may
result from blood loss or placental separation.

A client is diagnosed with hyperemesis gravidarum after coming to the antepartum
unit with persistent vomiting, weight loss, and hypovolemia. While gathering data
from the client, which information is most significant?
