Question

Breast engorgement occurs on the second or third postpartum day. Which of the following processes causes engorgement?

a) Increased estrogen levels.
b) Decreased blood flow to the breasts.
c) Milk production initiation.
d) Relaxation of mammary ducts.

Answer 1

Breast engorgement is caused by the initiation of milk production, which occurs on the second or third postpartum day due to the release of prolactin. The release of prolactin from the anterior pituitary causes the mammary glands to produce milk, leading to engorgement.

Step-by-step explanation:

Breast engorgement is caused by the initiation of milk production (c), which occurs on the second or third postpartum day. When the baby begins suckling at the breast, signals are sent to the hypothalamus causing the release of prolactin from the anterior pituitary. Prolactin causes the mammary glands to produce milk, leading to engorgement.
