A lady vaginally delivered a baby in the labor room. The on-duty nursing officer knows that after 7 days post-delivery, which type of lochia comes from the vagina?

Appeared in: NORCET 2 - 2021 (shift-1)

Explanation

Lochia is the vaginal discharge during the puerperium, the period after childbirth.
It progresses through three stages: rubra, serosa, and alba.
Lochia serosa is the second stage, typically occurring from day 5 to day 9 postpartum.
Since the question specifies 7 days post-delivery, this falls within the timeframe for lochia serosa.
Lochia serosa is characterized by a pinkish-brown color and a more watery consistency compared to lochia rubra, as it contains old blood, serum, leukocytes, and tissue debris.

Option A: Lochia rubra is the first stage of postpartum discharge, lasting for the first 1 to 4 days. It is characterized by its bright red color due to the presence of fresh blood. By day 7, the discharge should have transitioned out of this stage.
Option C: Lochia alba is the final stage, beginning around day 10 and lasting up to 6 weeks. It is yellowish-white in color. Day 7 is too early for lochia alba to appear.
Option D: This option is incorrect because there is a specific, expected type of lochia at 7 days postpartum, which is lochia serosa. The absence of lochia would be an abnormal finding.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Postpartum physiological changes and assessment in the correct sequence, documenting the action clearly, and monitoring for the expected response.
A nurse's assessment of lochia is crucial for monitoring postpartum recovery. The amount, color, odor, and consistency are checked regularly.
Deviations from the normal pattern can indicate complications. For example, the persistence of lochia rubra beyond the first few days may suggest subinvolution of the uterus or retained placental fragments, increasing the risk of postpartum hemorrhage.
A foul odor at any stage is a sign of infection (puerperal sepsis) and must be reported to the physician immediately.

How to Approach the Question

Identify the key term in the question, which is 'lochia'.
Recall the three stages of lochia: rubra, serosa, and alba.
Remember the specific timeline for each stage.
The question asks for the type of lochia at '7 days' post-delivery.
Match the 7-day mark to the correct stage. Lochia rubra is days 1-4, lochia serosa is days 5-9, and lochia alba is day 10 onwards.
Conclude that day 7 falls within the lochia serosa stage.
