Correct Answer is A

Explanation

A. "The purpose of this medication is to boost fetal lung maturity." Betamethasone is a corticosteroid given to promote fetal lung maturity by stimulating surfactant production, especially in preterm labor.

B. "The purpose of this medication is to stop preterm labor contractions." Tocolytics, not corticosteroids, are used to stop preterm labor contractions. Betamethasone is not designed to halt contractions.

C. "The purpose of this medication is to halt cervical dilation." Betamethasone does not affect cervical dilation. Its role is to support fetal lung development.

D. "The purpose of this medication is to increase the fetal heart rate." Betamethasone does not directly influence fetal heart rate. Its primary use is to mature fetal lungs in anticipation of early birth.

A. Assist in initiating IV access and administering IV fluid bolus B. Call for assistance immediately C. Apply finger pressure to the presenting part D. Administer oxygen at 10 L/min via a nonrebreather

Correct Answer is B

Explanation

A. Assist in initiating IV access and administering IV fluid bolus: While IV fluids may be needed, the priority in this case is to address the umbilical cord prolapse, which poses an immediate risk to the baby.

B. Call for assistance immediately: Cord prolapse is an obstetric emergency that requires immediate assistance to prevent fetal hypoxia. Rapid response is crucial to save the baby.

C. Apply finger pressure to the presenting part: Although applying pressure to relieve compression on the cord is necessary, the first action should be to summon help to manage the emergency.

D. Administer oxygen at 10 L/min via a nonrebreather: Oxygen is important to improve maternal and fetal oxygenation, but calling for help is the immediate priority in this life-threatening situation.
