Practice questions
- A review of deaths associated with antepartum haemorrhage identifies which group as the main causes?
- A pregnant patient has massive antepartum haemorrhage. Which statement best reflects the management principle described in the review?
- During management of massive obstetric haemorrhage, which approach is supported by the review?
- A meta-analysis of regular maternal opiate use reported a pooled crude odds ratio for APH of 2.33 (95% CI 1.32–4.30). Which interpretation is most accurate?
- Why did the meta-analysis of maternal opiate use caution against attributing the observed APH association entirely to opiates?
- A meta-analysis comparing single with double embryo transfer reported an APH odds ratio of 0.35 (95% CI 0.15–0.82) for single embryo transfer. What does this estimate indicate?
- Which conclusion about the single- versus double-embryo-transfer APH finding is best supported by the meta-analysis?
- In a systematic review of aspirin in low-risk nulliparous women with singleton pregnancies, the pooled APH relative risk was 1.06 (95% CI 0.66–1.70). Which interpretation is correct?
- A clinician interprets the aspirin meta-analysis as proving that aspirin has exactly no effect on APH. What is the most appropriate correction?
- The aspirin meta-analysis described its participants as low-risk nulliparous women with singleton pregnancies. Which patient most closely matches that population?
- A systematic review of regional maternal haemorrhage prevalence using specified blood-loss definitions reported which finding about APH prevalence?
- A researcher claims that APH must be absent or negligible because a regional prevalence review found no studies reporting its prevalence. Which response is most defensible?
- A patient develops severe antepartum bleeding during oxytocin induction. At emergency caesarean delivery, a lower-segment myometrial defect is found with intact serosa. Which rare diagnosis is specifically consistent with the reported case literature?
- During exploration for severe obstetric bleeding, the surgeon finds a laceration in the inner myometrium while the uterine serosa is intact. Which diagnosis best describes this finding?
- In the reported case of inner myometrial laceration with severe haemorrhage, which uterine-preserving haemostatic approach was described?
- According to the inner myometrial laceration review, how should hysterectomy be positioned when considering uterine preservation?
- Which statement about the pathogenesis of inner myometrial laceration is supported by the review?
- A 2025 systematic review classified antepartum haemorrhage as a risk factor for postpartum haemorrhage. How strong was the reported association category?
- Which statement best distinguishes the systematic review's finding about APH and subsequent PPH from a cause-specific diagnosis?
