A nurse is assisting with an emergency cesarean delivery for a client who has placenta previa and is experiencing profuse bleeding.
Which of the following medications should the nurse anticipate administering to this client after delivery?
Methylergonovine (Methergine)
Carboprost tromethamine (Hemabate)
Misoprostol (Cytotec)
Terbutaline (Brethine)
The Correct Answer is C
The correct answer is choice C. Misoprostol (Cytotec). This medication is used to prevent postpartum hemorrhage (excessive bleeding after delivery) in women with placenta previa. Placenta previa is a condition where the placenta covers the opening of the cervix and can cause severe bleeding during pregnancy.
Choice A is wrong because Methylergonovine (Methergine) is a medication that stimulates uterine contractions and can increase bleeding in women with placenta previa.
Choice B is wrong because Carboprost tromethamine (Hemabate) is also a medication that causes uterine contractions and can worsen bleeding in women with placenta previa.
Choice D is wrong because Terbutaline (Brethine) is a medication that relaxes uterine muscles and can delay labor, but it does not prevent postpartum hemorrhage in women with placenta previa.
Normal ranges for blood loss after delivery are less than 500 mL for vaginal delivery and less than 1000 mL for cesarean delivery.

Correct Answer is A
Explanation
Retained placental fragments are the most common cause of late postpartum hemorrhage.Retained placental fragments can lead to infection and subinvolution of the placental site, which prevents the uterus from contracting and stopping the bleeding.
Choice B is wrong because uterine atony is the most common cause of early postpartum hemorrhage, not late postpartum hemorrhage.Uterine atony occurs when the uterus fails to contract after delivery.
Choice C is wrong because trauma is a rare cause of late postpartum hemorrhage.Trauma can occur during delivery and cause lacerations or hematomas that can bleed later, but this is uncommon.
Choice D is wrong because lacerations are also a rare cause of late postpartum hemorrhage.Lacerations can occur in the cervix, vagina or perineum during delivery and cause bleeding, but this usually happens immediately or within 24 hours after delivery.
Correct Answer is A
Explanation
Urine output of 40 mL/hr indicates an improvement in the client’s condition.According to the MSF Medical Guidelines, the objective of resuscitation in postpartum hemorrhage is to maintain a urine output of at least 30 mL/hour.
A urine output of 40 mL/hr suggests that the client has adequate fluid replacement and blood transfusion therapy.
Choice B is wrong because a pulse rate of 110 beats/min is still high and indicates tachycardia.
Tachycardia is a sign of hypovolemia and shock due to blood loss.The normal pulse rate for an adult is 60 to 100 beats/min.
Choice C is wrong because a hematocrit level of 32% is low and indicates anemia.
Anemia is a complication of postpartum hemorrhage due to reduced red blood cell count.The normal hematocrit level for women is 36% to 48%.
Choice D is wrong because a blood pressure of 90/60 mm Hg is low and indicates hypotension.
Hypotension is a sign of hypovolemia and shock due to blood loss.The normal blood pressure for an adult is 120/80 mm Hg.
