A nurse is caring for a client who is 1 hr postpartum and unable to urinate. Which of the following actions should the nurse take?

A. Place the client's hands in warm water: This action can stimulate the client’s natural reflex to urinate. The warm water helps relax the muscles involved in urination. B. Administer a benzodiazepine: Incorrect. Benzodiazepines are not indicated for difficulty urinating postpartum and can cause unnecessary sedation. C. Place an ice pack on the client's perineum: Incorrect. An ice pack is typically used to reduce swelling or discomfort, but it is not a primary intervention for urinary retention. D. Perform a fundal massage: Incorrect. Fundal massage is performed to assess uterine tone, not for urinary retention.
