The nurse is assessing the lochia on a 1-day postpartum patient.The nurse notes that the lochia is red and has a foul-smelling odor.The nurse determines that this assessment finding:

Choice A rationaleIncreasing ambulation is generally encouraged in the postpartum period to prevent complications like thrombophlebitis, but it does not address the potential cause of foul-smelling lochia. Foul odor is a key indicator of infection, and ambulation will not resolve an existing infection.Choice B rationaleIncreasing oral fluids is important for hydration in the postpartum period, but it will not directly address a foul-smelling odor in the lochia. While adequate hydration supports overall healing, it does not treat an infection. A foul odor strongly suggests a localized infectious process in the uterus.Choice C rationaleLochia that is red (rubra) is normal in the first few days postpartum. However, a foul-smelling odor is an abnormal finding and a significant indicator of a potential uterine infection, also known as endometritis or puerperal infection. Further assessment and intervention are required to identify and treat the infection.Choice D rationaleNormal lochia progresses from rubra (red) to serosa (pinkish-brown) to alba (yellowish-white) over several weeks postpartum. Normal lochia should have a fleshy, not foul, odor. A foul smell is an abnormal finding that suggests an infectious process within the uterus and requires prompt attention.
