What type of lochia will the nurse assess initially after delivery?

A. Serosa: Lochia serosa appears several days after delivery, typically around day 4 to 10, and is pinkish or brownish in color. It is not the initial type of lochia observed immediately postpartum. B. Rubra: Lochia rubra is the initial postpartum vaginal discharge, appearing within the first 1–3 days. It is bright red, contains blood, decidual tissue, and mucus, reflecting normal uterine healing and shedding of the lining. C. Vaginalis: Vaginalis is not a recognized classification of lochia. The standard types include rubra, serosa, and alba. D. Alba: Lochia alba occurs later, around 10–14 days postpartum, and can persist for several weeks. It is whitish or yellowish and contains mostly leukocytes and epithelial cells rather than blood.
