A nurse is assessing a client 3 days following a hysterectomy. Which of the following findings should the nurse identify as an indication the client is developing a complication?

Unilateral leg swelling after hysterectomy is a classic sign of deep vein thrombosis (DVT), a serious postoperative complication. DVT risk is elevated following pelvic surgery due to venous stasis, vascular injury, and hypercoagulability. Mild pain at the surgical site is expected. Increased hemoglobin and increased urinary output are positive postoperative findings indicating recovery, not complications.
