A nurse is caring for a client who had a vaginal delivery 2 hr ago and is reporting increasing perineal pain and pressure.The nurse examines the client's perineum and sees a 4 cm (1.6 in) area of purplish discoloration with swelling.The nurse should interpret these findings as which of the following?

Choice A rationaleA hematoma presents as a localized collection of blood outside the blood vessels, causing a purplish discoloration and swelling, often resulting from trauma during delivery.Choice B rationaleRetained placental fragments may cause postpartum hemorrhage and infection but would not present as a localized purplish swelling on the perineum.Choice C rationaleA laceration would involve a tear in the tissue, causing bleeding and pain, but not necessarily a purplish discoloration with localized swelling unless associated with a hematoma.Choice D rationaleEcchymosis refers to bruising but is typically a more diffuse discoloration rather than a localized swelling and purplish area as seen with a hematoma.
