A client who has just delivered a baby is at risk for postpartum hemorrhage due to uterine atony.

Which of the following interventions should the nurse include in the plan of care?

Oxytocin is a hormone that stimulates uterine contractions and helps prevent postpartum hemorrhage due to uterine atony.Uterine atony is the most common cause of postpartum hemorrhage, and it occurs when the uterus does not contract enough to stop the bleeding from the placental site.

Choice A is wrong because encouraging frequent voiding does not directly affect uterine contractions.However, it can help reduce bladder distension, which can interfere with uterine contraction and cause bleeding.

Choice B is wrong because magnesium sulfate (MgSO4) is used to prevent seizures in preeclampsia and eclampsia, not to prevent postpartum hemorrhage.In fact, magnesium sulfate can cause uterine relaxation and increase the risk of bleeding.

Choice C is wrong because encouraging early ambulation does not prevent postpartum hemorrhage due to uterine atony.Early ambulation can help prevent thromboembolic complications, such as deep vein thrombosis and pulmonary embolism, but it does not affect uterine contractions.

This is because a normal urine output in the postpartum period ranges from1.03 to 1.40 cc/kg/hror500 to 1000 mLper void.A urine output of 200 mL for the past 8 hours is much lower than the normal range and indicatesoliguria, which can be a sign ofhypovolemia,renal failure, orurinary retentiondue to postpartum hemorrhage.

Choice B is wrong because a weight decrease of 2 pounds since delivery is normal and expected due to the loss of blood, amniotic fluid, and placenta.

Choice C is wrong because a blood pressure of 110/70 mm Hg is within the normal range and does not indicate hypotension or hypertension.

Choice D is wrong because a hemoglobin level of 12 g/dL is also within the normal range and does not indicate anemia or polycythemia.
