Question

What is uterine atony, and how does it cause PPH?

a. Uterine relaxation; inhibits blood clotting.
b. Uterine overactivity; increases blood flow.
c. Uterine distension; prevents blood loss.
d. Uterine contraction; restricts blood vessels.

Answer 1

Uterine atony is a condition where the uterus fails to contract properly after childbirth, leading to excessive bleeding and PPH.

Step-by-step explanation:

Uterine atony is a condition where the uterus fails to contract properly after childbirth, leading to excessive bleeding and postpartum hemorrhage (PPH).

The correct answer is d. Uterine contraction; restricts blood vessels. Uterine atony causes PPH because without proper contraction, the blood vessels in the uterus are not restricted, resulting in excessive bleeding.
