题目：
A client receiving haloperidol (Haldol) complains of a stiff jaw and difficulty swallowing. Which of the following should be the nurse’s first action
A. Reassure the client and administer as-needed lorazepam (Ativan) IM.
B. Administer as-needed dose of benztropine (Cogentin) by mouth as ordered.
C. Administer as-needed dose of benztropine (Cogentin) IM as ordered.
D. Administer as-needed dose of haloperidol (Haldol) by mout
答案：
参考答案：C
解析：The client is most likely suffering from muscle rigidity due to haloperidol. I.M. Benztropine should be administered to prevent asphyxia or aspiration. Lorazepam treats anxiety, not extrapyramidal effects. Another dose of haloperidol would increase the severity of the reaction.
