Sequence of lochia during puerperium is: March 2012
**Core Concept**
The puerperium is the postpartum period, and **lochia** refers to the vaginal discharge that occurs after childbirth. This discharge consists of blood, bacteria, and tissue from the uterus lining. Understanding the sequence of lochia types is crucial for assessing postpartum recovery.
**Why the Correct Answer is Right**
The correct sequence of lochia is characterized by an initial phase of **lochia rubra**, which is rich in blood and lasts about 2-3 days. This is followed by **lochia serosa**, which has a serous consistency and less blood, occurring around 4-6 days postpartum. Finally, **lochia alba** or **lochia purulenta** (if infected) marks the last phase, which is more watery and can last up to 2-4 weeks. This sequence reflects the healing process of the uterus.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not accurately represent the known sequence of lochia.
**Option B:** Incorrect as it misrepresents the order.
**Option C:** Incorrect because it inaccurately describes the progression of lochia.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the sequence and characteristics of lochia can indicate the postpartum woman's healing status. Any deviation from the expected sequence or characteristics, such as prolonged **lochia rubra**, could signal a complication.
**Correct Answer:** D. Lochia rubra, serosa, and then alba.
