A nurse is providing teaching about the expected effects of magnesium sulfate to a client who is at 28 weeks of gestation and has preeclampsia.
Which of the following responses by the nurse is appropriate?
"This medication increases cardiac output.”.
"This medication prevents seizures.”.
"This medication stabilizes the fetal heart rate.”.
"This medication improves tissue perfusion.”.
The Correct Answer is B
Choice A rationale:
Magnesium sulfate does not increase cardiac output. It is a central nervous system depressant and muscle relaxant.
Choice B rationale:
Magnesium sulfate is given to clients with preeclampsia to prevent seizures, which can be a complication of this condition.
Choice C rationale:
Magnesium sulfate does not directly stabilize the fetal heart rate. Its primary use in preeclampsia is seizure prevention.
Choice D rationale:
While magnesium sulfate can cause vasodilation, which could improve tissue perfusion, its primary use in preeclampsia is to prevent seizures.
