Final answer:
The clinical findings associated with placenta previa include vaginal bleeding and, in the case of placenta abruption, both severe vaginal bleeding and abdominal pain. Elevated blood pressure is not associated with these conditions but with preeclampsia, and increased fetal movement is not a typical sign of placental problems.
Step-by-step explanation:
The clinical findings associated with placenta previa and placenta abruption primarily include:
- A) Vaginal bleeding
- C) Severe abdominal pain
Placenta previa occurs when the placenta partially or completely covers the opening of the cervix, leading to a significant risk of antepartum hemorrhage, which is profuse vaginal bleeding after week 24 of pregnancy. This condition is a leading cause of antepartum hemorrhage in pregnancies and it's essential for obstetricians to carefully monitor such situations.
On the other hand, placenta abruption is characterized by the premature separation of the placenta from the uterus before childbirth, which can also lead to severe vaginal bleeding, in addition to severe abdominal pain, and is a medical emergency. Both conditions are serious and require immediate attention from healthcare professionals.
It's important to note that B) Elevated blood pressure is more associated with conditions such as preeclampsia and D) Increased fetal movement is not typically associated with these placental problems. While an obstetrician must examine the expelled placenta after birth to ensure no fragments remain, the clinical signs during pregnancy for these conditions are distinct.
