When administering magnesium sulfate to a client with preeclampsia, the nurse understands that this drug is given to:
A. Prevent seizures
B. Reduce blood pressure
C. Slow the process of labor
D. Increase dieresis
The chemical makeup of magnesium is similar to that of calcium and, therefore, magnesium will act like calcium in the body. As a result, magnesium will block seizure activity in a hyper stimulated neurologic system by interfering with signal transmission at the neuromuscular junction.
