单项选择题
A physician schedules an invasive procedure for a client with acquired immunodeficiency syndrome-related dementia. He lives with his male companion, who is present. His mother, who lives in another state, is also present. The nurse anticipates that the consent form should be signed by（）
A. the companion.
B. the mother.
C. the client.
D. two physicians.
答案
参考答案：B
解析：
The mother should sign the consent form because she’s the closest living relative. The client can’t sign because of his diagnosis. The companion, although a close significant other, can’t sign because he isn’t a blood relative. Two physicians need not sign a consent form when a relative is available.
