A nurse is assessing a client who is 8 hour postpartum and multiparous. Which of the following findings should alert the nurse to the client's need to urinate?

A. Moderate lochia rubra is an expected finding in the early postpartum period as the uterus sheds decidual tissue and blood. This finding alone does not specifically indicate bladder distention or urinary retention. B. A fundus positioned above the umbilicus in the early postpartum period suggests uterine displacement, commonly caused by a distended bladder. Bladder fullness prevents effective uterine contraction and can elevate and deviate the fundus. C. Moderate labial swelling is common after vaginal delivery due to tissue trauma and vascular congestion. While it may cause discomfort with voiding, it does not indicate the physiologic need to urinate. D. A blood pressure of 130/84 is slightly elevated but can be normal postpartum due to pain, fluid shifts, or stress. This vital sign change is not associated with bladder distention or urinary retention.
