Final answer:
The matches for the types of placental abruption are: 1. Marginal - Blood noticed on vaginal exam, 2. Partial/Central - Pain as the primary symptom, and 3. Complete - Lack of fetal heart tones. These symptoms reflect varying degrees of separation of the placenta from the uterus, affecting fetal oxygenation and potentially requiring emergency delivery.
Step-by-step explanation:
The question regarding the matching of signs and symptoms (s/sx) for each type of abruption pertains to the complication known as placental abruption, in obstetrics. This is a critical condition wherein the placental lining has partially or completely separated from the uterus before delivery, which can compromise fetal oxygenation. Here are the matches:
- 1. Marginal: B. Blood noticed of vaginal exam.
- 2. Partial/Central: C. Pain is the primary symptom.
- 3. Complete: A. Lack of fetal heart tones.
Marginal abruptions may present with vaginal bleeding without significant pain, while more central or partial abruptions tend to cause pain and possibly also bleeding. A complete abruption, which is the most severe, may lead to the absence of fetal heart tones due to significant compromise of fetal circulation requiring immediate medical intervention like Caesarian section.
