When administering magnesium sulfate to a client with preeclampsia, the nurse understands that this drug is given to:
Increase diuresis.
Prevent seizures.
Reduce blood pressure.
Slow the process of labor.
The Correct Answer is B
Choice A rationale
Magnesium sulfate is not given to increase diuresis; this is not its primary effect and is incorrect in the context of treating preeclampsia.
Choice B rationale
Magnesium sulfate is administered to prevent seizures in patients with preeclampsia. It acts as a central nervous system depressant and helps in preventing eclampsia.
Choice C rationale
Although magnesium sulfate may have a mild effect on reducing blood pressure due to its vasodilatory properties, this is not its primary purpose in the management of preeclampsia.
Choice D rationale
Magnesium sulfate is not used to slow the process of labor; its main role is seizure prophylaxis in preeclampsia.

Correct Answer is ["B","C","E"]
Explanation
Choice A rationale
Pumping up the vacuum manually to the pressure indicated on the pump is a standard procedure but doesn't directly minimize liability.
Choice B rationale
Recognizing cup detachment (pop off) as a warning sign is critical, as it indicates excessive force or poor positioning, which can lead to fetal or maternal injury.
Choice C rationale
Limiting the cup's attachment to the fetal head to 5 to 10 minutes reduces the risk of scalp injury and other complications, thus minimizing liability.
Choice D rationale
Timing the procedure from insertion of the cup into the vagina until the birth is a guideline but doesn't specifically address liability concerns.
Choice E rationale
Releasing pressure between contractions prevents continuous suction on the fetal head, reducing the risk of injury and thereby minimizing liability.
Correct Answer is D
Explanation
Choice A rationale
Oxytocin is used to induce or augment labor, not typically used before an external version, which is a procedure to turn a breech baby to a head-down position.
Choice B rationale
Methylergonovine is used to prevent or control postpartum hemorrhage by inducing strong uterine contractions, not indicated before an external version.
Choice C rationale
Betamethasone is a corticosteroid used to accelerate fetal lung maturity in preterm labor, not required for an external version.
Choice D rationale
Terbutaline is a tocolytic agent used to relax the uterus, making it easier to manipulate the fetus during the external version procedure.
