Correct Answer is A
Explanation
Choice A rationale
Painless, bright red vaginal bleeding at 36 weeks gestation is a classic sign of placenta previa, where the placenta is abnormally implanted in the lower uterine segment, covering the cervix, and causing bleeding without pain.
Choice B rationale
Threatened abortion is characterized by vaginal bleeding before 20 weeks of gestation with or without abdominal pain. At 36 weeks, the term would be inappropriate, and the symptoms do not match.
Choice C rationale
Abruptio placentae involves painful vaginal bleeding due to premature placental separation. The presence of pain differentiates it from placenta previa.
Choice D rationale
Preterm labor may present with contractions, cervical changes, and possible bleeding, but the key feature distinguishing it from placenta previa is the presence of uterine contractions and pain, which are absent in this scenario.
Correct Answer is C
Explanation
Choice A rationale
A BMI of 28 is considered overweight, which can be a risk factor for preeclampsia but is not as strong an indicator as gestational hypertension. BMI alone does not automatically place someone at high risk.
Choice B rationale
Age of 24 is within the typical childbearing age range and is not considered a high-risk factor for preeclampsia. Extremes of maternal age (below 18 or above 35) are more significant risk factors.
Choice C rationale
Gestational hypertension is a significant risk factor for developing preeclampsia. It indicates elevated blood pressure during pregnancy, which can lead to preeclampsia if not managed properly.
Choice D rationale
Gravida 3 Para 2 indicates a woman who has had two previous pregnancies carried to viable gestational age. While multiparity can influence pregnancy outcomes, it is not a direct high-risk factor for preeclampsia like gestational hypertension is. .
