Final answer:
A soaked perineal pad in 15 minutes or less after vaginal delivery may indicate postpartum hemorrhage (PPH).
Step-by-step explanation:
A soaked perineal pad in 15 minutes or less after vaginal delivery may indicate postpartum hemorrhage (PPH). PPH is defined as a blood loss of more than 500 ml after vaginal birth. It can be caused by factors such as uterine atony, retained placenta, or trauma to the birth canal. If a soaked perineal pad is observed, it is important to notify a healthcare provider immediately for further evaluation and management.
