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?

Wait 15 min to administer the medication after the client saturates a perineal pad.

Administer the medication once if the client saturates the perineal pad within 15 min.

Offer the medication now to prevent saturation of the perineal pad.

Administer the medication every 15 min regardless of pad saturation.
