Understanding Placental Abruption

What is the primary function of the placenta in pregnancy?

• To produce hormones for the mother

• To provide oxygen and nutrients to the fetus

• To regulate the mother's blood pressure

• To protect the fetus from external harm

What happens when the uterine arteries rupture in placental abruption?

• Blood accumulates between the uterus and placenta

• The uterine wall thickens

• The placenta becomes more attached to the uterus

• The fetus receives more oxygen

What is a key symptom of placental abruption that differentiates it from placenta previa?

• Decreased uterine contractions

• Painless vaginal bleeding

• Painful vaginal bleeding

• Increased fetal movement

Why might ultrasound be challenging in diagnosing placental abruption?

• Ultrasound is harmful to the fetus

• Blood and placenta appear similar on ultrasound

• Ultrasound is not used during pregnancy

• Ultrasound cannot penetrate the uterine wall

What is the primary goal of uterine contractions in the context of placental abruption?

• To facilitate fetal movement

• To increase blood flow to the placenta

• To separate the placenta from the uterus

• To control bleeding by compressing arteries

When is delivery typically considered in cases of placental abruption?

• When the mother is stable

• When the baby is past 34-36 weeks and stable

• When the abruption is minor

• When the baby is too young to survive outside the womb

What is a common cause of placental abruption related to lifestyle?

• Smoking or cocaine use

• Excessive exercise

• Lack of sleep

• High protein diet

How does trauma contribute to placental abruption?

• By stabilizing the uterine arteries

• By enhancing blood flow to the placenta

• By causing the placenta to shear away from the uterus

• By increasing uterine contractions

Which chronic condition is a risk factor for placental abruption?

• Asthma

• Anemia

• Hypertension

• Diabetes

What is the ultimate cause of placental abruption?

• Rupture of uterine arteries

• Excessive fetal movement

• Decreased uterine size

• Increased maternal blood pressure
