Question 1

A client at 28 weeks is admitted with preterm labor. Which medication does the nurse expect to administer to promote fetal lung maturity?

Accepted Answer

Betamethasone

Answer

Betamethasone is a corticosteroid given to mothers before 34 weeks to accelerate fetal lung surfactant production and reduce respiratory distress syndrome.

Question 2

During a routine prenatal visit at 28 weeks, a Rh-negative client with a Rh-positive partner is prescribed Rho(D) immune globulin (RhoGAM). What is the purpose?

Accepted Answer

Prevent maternal sensitization to Rh-positive fetal blood cells

Answer

RhoGAM prevents Rh sensitization by destroying any fetal Rh-positive cells before the mother's immune system can produce antibodies.

Question 3

The nurse is performing a newborn assessment and notes the Moro reflex is absent on one side. This finding is most associated with:

Accepted Answer

Brachial plexus injury

Answer

A unilateral absent Moro reflex suggests brachial plexus injury (Erb's palsy), often resulting from shoulder dystocia during delivery.

Question 4

A client with gestational hypertension is being monitored. Which additional finding would upgrade the diagnosis to preeclampsia?

Accepted Answer

Proteinuria of 300 mg in a 24-hour urine

Answer

Preeclampsia is diagnosed when gestational hypertension is accompanied by proteinuria ≥300 mg/24 hours or other end-organ involvement.

Question 5

A nurse assists with the delivery of a newborn with shoulder dystocia. After delivery, which assessment is the priority?

Accepted Answer

Brachial plexus function and clavicle integrity

Answer

Shoulder dystocia can cause brachial plexus injury and clavicle fractures, so assessing arm movement and clavicle palpation is the priority.
