Choice A rationale

Preparing for an emergency cesarean birth may be necessary in some cases of preeclampsia, particularly if there are signs of fetal distress or if the condition is not responding to treatment. However, in this scenario, the client’s symptoms are indicative of magnesium toxicity, not worsening preeclampsia.

Choice B rationale

Positioning the client in Trendelenburg (with the head lower than the feet) is not typically used in the management of preeclampsia or magnesium toxicity.

Choice C rationale

Discontinuing the medication infusion is the correct action in this scenario. The client’s symptoms (respiratory rate of 10/min and absent deep-tendon reflexes) are indicative of magnesium toxicity, a potential complication of magnesium sulfate therapy. Magnesium sulfate is used in the management of preeclampsia to prevent seizures, but it can cause toxicity if the levels become too high. If signs of toxicity occur, the infusion should be discontinued immediately.

Choice D rationale

Assessing maternal blood glucose may be necessary in some cases, particularly if the client has a history of diabetes. However, it is not the priority in this scenario, as the client’s symptoms are indicative of magnesium toxicity, not hyperglycemia.

Choice A rationale

Tilt the client onto her right side with her legs elevated to at least 30 degrees. This action is not the most immediate step to take. While it can help improve venous return and thus cardiac output, it does not directly address the issue of postpartum hemorrhage.

Choice B rationale

Administer oxytocin by continuous IV infusion. Oxytocin is a medication that can stimulate uterine contractions and help control postpartum bleeding. However, it should be administered after the nurse has assessed the uterus and determined that it is not contracting effectively on its own.

Choice C rationale

Insert an indwelling urinary catheter. While a full bladder can inhibit effective uterine contractions and contribute to bleeding, inserting a catheter is not the first step in managing a postpartum hemorrhage.

Choice D rationale

Massage the client’s fundus to promote contractions. This is the correct answer. Fundal massage stimulates the uterus to contract, which can help control postpartum bleeding. It is a first-line intervention for a boggy uterus and postpartum hemorrhage.
