Quick answerUterine atony; massage the fundus and empty the bladder by straight catheterization; monitor fundal tone and position and cumulative quantified blood loss.
Why this is correctBleeding that slows when the uterus firms under massage comes from the placental site, which means tone is the problem. The fundus is above the umbilicus and pushed to the right, and the client has not voided, so a full bladder is keeping the uterus from contracting. Massage and bladder emptying restore contraction; fundal firmness, return to midline, and the quantified blood-loss total show success.
Easy analogy or mental pictureThe uterus is a sponge that has to be squeezed shut over open vessels. A full bladder is a book wedged under the sponge, so it cannot close no matter how hard you press.
Memory hookBoggy + shifted = rub and drain (massage the fundus, empty the bladder).
NCLEX decision ruleWhen postpartum bleeding responds to fundal massage and the uterus is displaced, treat tone first and empty the bladder; look for trauma or tissue only when the uterus is firm and bleeding continues.
Why the other choices are wrongA laceration bleeds despite a firm uterus; here bleeding slows with massage and the small first-degree tear is not bleeding, so repair and perineal pain do not track the hemorrhage. Retained tissue is unlikely with an intact placenta, so manual removal is not indicated, and lochia odor tracks later infection. Uterine inversion causes a missing or dimpled fundus, not a high displaced one. Trendelenburg positioning is an outdated shock measure that impairs ventilation and does not treat the cause. Temperature reflects infection, not bleeding control.
