参考答案: D

参考解析: Magnesium sulfate is a central nervous system depressant used as an anticonvulsant for severe PIH. It may depress respirations to a dangerously low and even life-threatening level. Therefore, the nurse must assess the client's respiratory rate before administering the drug. If the client's respiratory rate is below 12 to 14 breaths/ minute, the physician should be notified and the drug should be withheld.
