Lochia refers to which postpartum phenomenon and what is its typical color progression?

• A. Lochia is a postpartum lozenge.
• B. Lochia is vital signs after birth.
• C. Lochia is vaginal discharge after birth; rubra (days 1–3), serosa (days 4–10), alba (weeks 2–6).
• D. Lochia refers to umbilical stump care.

Answer: (C)

Lochia is the vaginal discharge after birth as the uterus sheds tissue and then heals. Its color progression mirrors the healing process: a bright red discharge (rubra) in the first few days, transitioning to a pinkish-brown (serosa) from about days 4 to 10, and finally a pale yellow‑white (alba) that can continue for several weeks (typically about 2 to 6 weeks). This pattern indicates normal involution of the uterus and decreasing bleeding as healing progresses. If bleeding becomes heavy, has a foul odor, or lasts much longer than a few weeks, that would warrant medical attention. Lochia is not a lozenge, nor a description of vital signs, and it is unrelated to umbilical stump care.
