OB Final Review

Which of the following is the priority assessment immediately after the rupture of membranes?

• Fetal heart rate

• Maternal temperature

• Degree of dilation

• Frequency of contractions

Answer explanation

The priority assessment after the rupture of membranes is the fetal heart rate. This is crucial to ensure the fetus is not in distress and to monitor for any potential complications.

A nurse is caring for a client at 30 weeks gestation with signs of preterm labor. Which medication might be given to promote fetal lung maturity?

• Oxytocin

• Betamethasone

• Magnesium sulfate

• Misoprostol

Answer explanation

Betamethasone is a corticosteroid that promotes fetal lung maturity by accelerating surfactant production in the lungs. This is crucial for preterm infants to reduce the risk of respiratory distress syndrome.

Which fetal position is most favorable for vaginal delivery?

• Occiput posterior

• Occiput anterior

• Breech

• Transverse

Answer explanation

The occiput anterior position, where the baby's head is down and facing the mother's back, is most favorable for vaginal delivery. It allows for optimal alignment and easier passage through the birth canal.

What is the purpose of Leopold's maneuvers?

• To assess cervical dilation

• To determine fetal presentation and position

• To measure uterine contractions

• To assess amniotic fluid levels

Answer explanation

Leopold's maneuvers are used to determine fetal presentation and position by palpating the mother's abdomen. This helps healthcare providers assess how the fetus is positioned for delivery.

Which signs and symptoms are associated with preeclampsia?

• Proteinuria

• Headache

• Hypotension

• Blurred vision

• Epigastric pain

Answer explanation

Preeclampsia is characterized by high blood pressure and signs such as proteinuria, headache, blurred vision, and epigastric pain. Hypotension is not associated with preeclampsia, making it an incorrect choice.

What should the nurse include in postpartum education for a client after a C-section?

• Encourage ambulation

• Avoid lifting more than 10 lbs

• No driving for 2 weeks

• Report signs of infection

• Begin abdominal exercises immediately

Answer explanation

Postpartum education after a C-section should include encouraging ambulation to prevent complications, avoiding lifting over 10 lbs to protect the incision, refraining from driving for 2 weeks for safety, and reporting any signs of infection.

Which are signs of true labor?

• Cervical change

• Contractions that go away with rest

• Contractions felt in the back and abdomen

• Membrane rupture

• Fundal height increase

Answer explanation

Signs of true labor include cervical change, contractions felt in the back and abdomen, and membrane rupture. Contractions that go away with rest indicate false labor, while fundal height increase is not a direct sign of labor.

At what gestational age does the fundus typically reach the umbilicus?

• 12 weeks

• 16 weeks

• 20 weeks

• 24 weeks

Answer explanation

The fundus typically reaches the level of the umbilicus at around 20 weeks of gestation, marking a significant growth milestone in pregnancy.

Which milestones are matched with the correct gestational weeks? (SATA)

• Fetal heart tones heard with Doppler at 10-12 weeks

• Quickening felt around 28 weeks

• Viability usually considered at 24 weeks

• Neural tube closes by 12 weeks

• Surfactant production begins around 28 weeks

Answer explanation

Fetal heart tones can be detected by Doppler at 10-12 weeks, viability is typically recognized at 24 weeks, and surfactant production starts around 28 weeks. The other options are incorrect regarding their gestational weeks.

How much folic acid should a woman of childbearing age consume daily to prevent neural tube defects?

• 100 mcg

• 200 mcg

• 400 mcg

• 800 mcg

Answer explanation

Women of childbearing age should consume 400 mcg of folic acid daily to effectively reduce the risk of neural tube defects in developing babies, as recommended by health authorities.
