PB: Premature Rupture of membranes Verified Exam Questions and
Answers Latest update 2026/2027
Question:
define PROM, PPROM
Answer:
PROM = premature rupture of membranes before the onset of labor PPROM = preterm premature
rupture of membranes before onset of labor and before 37 weeks
Question:
etiology of PROM/PPROM
Answer:
intraamniotic infection h/o PPROM short cervical length second/third trimester bleeding low BMI low
SES cigarette smoking elicit drug use
Question:
what is the most significant maternal morbidity associated with term PROM?
Answer:
intrauterine infection (which the risk increases with the duration of ROM)
Question:
what percent of patients will delivery after membrane rupture occurs?
Answer:
50%`
Question:
what percent of women with PPROM will develop intrapartum infection? postpartum?
Answer:
intrapartum = 15-25% postpartum 15-20%
Question:
what are the most significant risks to the fetus after PPROM
Answer:
prematurity complications: RDS, sepsis, IVH, NES
, Question:
what percent of ROMs occur in previable infants?
Answer:
1% (the probability of neonatal death decreases with longer latency and advancing GA)
Question:
what percent of PROM before 24 weeks will have pulmonary hypoplasia?
Answer:
10-20%
Question:
how is PPROM diagnosed?
Answer:
history PE: avoid exam unless they are in active labor at the time of presentation; instead a speculum
exam will inspect for: cervicitis, umbilical cord prolapse, dilation/effacement check: ferning, pH, and
pooling Dx: speculum + u/s +FFN
Question:
what will cause false positive nitrazine results in PROM speculum exams
Answer:
semen blood bacterial vaginosis alkaline antiseptics
Question:
what is the significance of a fetal fibronectin test?
Answer:
it is a sensitive but nonspecific exam for ROM; a negative test indicates strongly that the membranes
are INTACT. A positive test is non-diagnostic
Question:
what does the initial management involve once PROM has been confirmed?
Answer:
1) GA, fetal presentation, fetal well being
Question:
2) check for intrauterine infection, abruption, fetal compromise
3) check GBS
what are indications for delivery if a patient is PROM?
Answer:
NRFHR or clinical amnionitis or abruption
