Question

A 19-year-old G2P1 woman at 30 weeks gestation presents with preterm premature rupture of membranes six hours ago. She denies labor. She takes prenatal vitamins and iron. She denies substance abuse, smoking or alcohol use. Her prior pregnancy was delivered vaginally at 41 weeks after spontaneous rupture of membranes. Her blood pressure is 110/70; pulse 84; temperature 98.6°F (37.0°C). Pertinent sonographic findings reveal a cervical length of 34 mm and an amniotic fluid index (AFI) of 3. What is the likelihood she will deliver within a week?

A. 80%
B. 40%
C. 20%
D. 10%
E. 5%

Answer 1

The likelihood that the woman will deliver within a week is approximately 80%.

Step-by-step explanation:

Preterm premature rupture of membranes (PPROM) is a condition where the amniotic sac leaks fluid before 38 weeks of gestation. This can be caused by a bacterial infection or by a defect in the structure of the amniotic sac, uterus, or cervix. In most cases of PPROM, labor begins within 48 hours of membrane rupture. Based on the information provided, the woman in question has a cervical length of 34 mm and an amniotic fluid index (AFI) of 3. These findings suggest a high risk of preterm delivery. The likelihood that she will deliver within a week is approximately 80% (choice A).
