40
Why is keeping bladder empty important when it comes to postpartum hemorrhage?
Distended bladder can push uterus up and to the side, leading to excessive bleeding
41
Why does postpartum put you at a great risk for urinary retention?
Due to swollen uterus and decreased bladder tone
42

43
Breastfeeding stimulates the release of what hormone from the pituitary gland?
Oxytocin
44
Mom can experience menopause-like symptoms after birth. Why is that?

Progesterone
47
What hormone suppresses ovulation?
Prolactin
48
What hormone promotes lactation?
Prolactin
49
Mom might feel cramping and gush of blood while breastfeeding. Why is that?
Because oxytocin is released when breastfeeding. Oxytocin causes contractions, leading to cramps. Contraction also pushes out pooled blood from vagina
