A nurse is caring for a client who is postpartum and has a prescription for oxytocin 10 units IM one time only for the saturation of a perineal pad in 15 min or less. How should the nurse interpret this prescription?

A. Give the medication each time the client saturates the perineal pad within 15 min. The prescription specifies "one time only," so it should not be repeated. B. Wait 15 min to administer the medication after the client saturates a perineal pad. The medication should be given immediately when excessive bleeding is identified, not after waiting. C. Administer the medication once if the client saturates the perineal pad within 15 min. A perineal pad saturation within 15 minutes indicates excessive postpartum bleeding, and oxytocin is used to promote uterine contractions and reduce hemorrhage. The nurse should administer the medication as soon as the condition is met. D. Offer the medication now to prevent saturation of the perineal pad. The medication should only be given when the excessive bleeding occurs, not as a preventive measure.
