For example, October 17 is 1017)

A.

Step 1 is: October 17 + 7 days = October 24.

B.

Step 2 is: October 24 - 3 months = July 24.

Correct Answer is A

Explanation

Choice A rationale

Betamethasone is a corticosteroid that accelerates fetal lung maturity by increasing the production of surfactant, which reduces respiratory distress syndrome in preterm infants.

Choice B rationale

While betamethasone can cause transient increases in fetal heart rate, its primary purpose is not to increase fetal heart rate. Its role is in enhancing lung maturity.

Choice C rationale

Betamethasone does not directly increase amniotic fluid levels. Its main function is in the maturation of fetal lungs.

Choice D rationale

Betamethasone is not used to stop preterm labor contractions. It is used to accelerate fetal lung development in preterm labor cases.

Correct Answer is A

Explanation

Choice A rationale

Uteroplacental insufficiency leads to late decelerations, which are characterized by a gradual decrease in fetal heart rate after the peak of a contraction. This indicates compromised blood flow between the uterus and placenta, affecting the fetus.

Choice B rationale

Umbilical cord compression usually causes variable decelerations, not late decelerations.

Choice C rationale

Maternal bradycardia does not cause changes in fetal heart rate patterns like late decelerations.

Choice D rationale

Fetal head compression causes early decelerations, which coincide with contractions, not late decelerations.
