Choice A rationale Notifying the healthcare provider immediately is premature. The initial nursing action for a soft, spongy fundus, indicative of uterine atony and a primary cause of postpartum hemorrhage, is to directly address the uterine muscle tone. Only after initial interventions have been performed and assessed for effectiveness, or if the client's condition deteriorates, would notification of the provider be the next appropriate step. Choice B rationale While documenting fundal height and consistency is an essential nursing responsibility, it is not the *first* intervention for a soft and spongy fundus. Documentation occurs after the immediate, critical intervention of fundal massage to stimulate uterine contractions and prevent excessive blood loss. This is part of the assessment-intervention-evaluation cycle. Choice C rationale A soft and spongy fundus indicates uterine atony, meaning the uterine muscle is not contracting effectively to compress blood vessels and prevent hemorrhage. Manual massage of the fundus stimulates uterine contractions, which is the most critical immediate intervention to prevent or manage postpartum hemorrhage by promoting vasoconstriction and clot formation at the placental site. Choice D rationale Elevating the client's legs might be a supportive measure for hypovolemic shock, but it is not the primary intervention for a soft, spongy fundus. The physiological priority is to address the uterine atony directly through fundal massage to promote uterine contraction and prevent further blood loss. Leg elevation does not directly impact uterine tone.
