Which description correctly lists the three stages of lochia and their typical timeframes?

• A. Lochia Rubra from Day 1–2; Lochia Serosa from Day 2–7; Lochia Alba After Day 7.
• B. Lochia Alba from Day 1–3; Lochia Rubra from Day 3–10; Lochia Serosa After Day 10.
• C. Lochia Rubra (Red) from Day 1–3; Lochia Serosa (Pink-Brown) from Day 3–10; Lochia Alba (Yellow-White) after Day 10 and up to 4–6 Weeks.
• D. Lochia Serosa from Day 1–3; Lochia Rubra from Day 3–10; Lochia Alba After Day 10.

Answer: (C)

Lochia progresses in a predictable pattern as the uterus heals after birth. The first phase, lochia rubra, is red and consists mainly of blood and tissue from the decidua and placental sites; it typically lasts from the first day up to about the third day. Next comes lochia serosa, a pink to brown-tinged discharge made of serous fluid, leukocytes, and debris, usually from around day three to day ten. Finally, lochia alba is the pale yellow-white discharge that marks the end of lochial flow, beginning after day ten and can continue for several weeks, often up to 4 to 6 weeks.

The description that fits these timelines is the one stating rubra from day 1–3, serosa from day 3–10, and alba after day 10 continuing for up to 4–6 weeks. Other options mix up the order or timing of the color changes, placing alba too early or shifting the serosa and alba timelines.
