Final answer:
The woman who gave birth 5 days ago is likely experiencing lochia serosa, which is a pinkish, thinner form of postpartum vaginal discharge that follows the initial lochia rubra phase.
Step-by-step explanation:
Five days postpartum, the nurse would expect to find that the woman is experiencing lochia serosa. This type of lochia is characterized by a pinkish discharge that is thinner than the initially experienced lochia rubra. Lochia rubra is the thick, dark red discharge that lasts for the first 2-3 days after giving birth. Following this phase, lochia serosa takes over and is present until about the tenth day postpartum. Lastly, lochia alba, which is a scant, creamy, or watery discharge, may continue for an additional 1-2 weeks. Therefore, the correct answer is d) Lochia serosa.
