单项选择题
The physician prescribes several drugs for a client with hemorrhagic stroke. Which drug order should the nurse question（）
A. Heparin sodium (Hep-Lock).
B. Dexamethasone (Deeadron).
C. Methyldopa (Aldomet).
D. Phenytoin (Dilantin).
答案
参考答案：A
解析：
Administration of heparin, an anticoagulant, could increase the bleeding associated with hemorrhagic stroke. Therefore, the nurse should question this order to prevent additional hemorrhage in the brain. For a client with hemorrhagic shock, dexamethasone may be used to decrease cerebral edema and pressure; methyldopa, to decrease blood pressure; and phenytoin, to prevent seizures.
