A woman with preeclampsia is being treated with bed rest and intravenous magnesium sulfate. The drug classification of this medication is:
a. tocolytic.
b. anticonvulsant.
c. antihypertensive.
d. diuretic.
B
The drug does slow down the frequency and intensity of uterine contractions, but is not used for that purpose in this scenario. This anticonvulsant drug acts by blocking neuromuscular transmission and depresses the central nervous system to control seizure activity. Decreased peripheral blood pressure is a therapeutic response (side effect) of the anticonvulsant, magnesium sulfate. Diuresis is a therapeutic response to magnesium sulfate.
