A patient,who is 8 months pregnant,has developed eclampsia and is receiving intravenous magnesium sulfate to prevent seizures.To determine if her infusion rate is too high,you should regularly

A) check the patellar reflex; if it becomes more and more hyperactive, her infusion rate probably is too high and she is at risk for respiratory depression or cardiac arrest.
B) check the patellar reflex; if it becomes weak or absent, her infusion rate probably is too high and she is at risk for respiratory depression or cardiac arrest.
C) check the patellar reflex; if it stays the same, her infusion rate probably is too high and she is at risk for respiratory depression or cardiac arrest.
D) check for seizure activity; if no seizures occur, her infusion rate is correct.
