Final answer:
Lochia that is red with small clots is known as lochia rubra, which typically lasts for 2-3 days postpartum before transitioning to lochia serosa and eventually lochia alba.
Step-by-step explanation:
Lochia that is red in color with several small clots is known as lochia rubra (Option B). This type of lochia is characterized by its thick, dark red appearance and typically continues for the first 2-3 days postpartum. Following the lochia rubra stage, there is a transition to lochia serosa, which is a thinner, pinkish discharge. After about the tenth postpartum day, lochia alba, a scant, creamy or watery discharge, may be present for an additional 1-2 weeks. There is no option for lochia purulenta as it is not a recognized stage of postpartum lochia.
