A nurse is caring for a client at 12 hours postpartum who has voided a total of 200 ml. Upon assessment the nurse notes that the bladder is distended. What is the priority intervention by the nurse?

A. Incorrect. 200 mL of urine in 12 hours is inadequate postpartum output and may indicate urinary retention. B. Correct. A distended bladder can interfere with uterine involution and increase the risk of postpartum hemorrhage. The provider should be notified, and interventions such as catheterization may be necessary. C. Incorrect. Waiting 24 hours before intervention is inappropriate when urinary retention is already evident. D. Encouraging fluids is helpful, but it does not directly address the immediate concern of a distended bladder.
