单选题 During a late stage of acquired immunodeficiency syndrome (AIDS), a client demonstrates signs of AIDS-related dementia. The nurse should give the highest priority to which nursing diagnosis?
A. Bathing or hygiene self-care deficit.
B. Ineffective cerebral tissue perfusion.
C. Dysfunctional grieving.
D. Risk for injury.

【正确答案】 D

【答案解析】In a client with AIDS, deterioration of the central nervous system (CNS) can lead to AIDS-related dementia. Because this type of dementia impairs cognition and judgment, it places the client at risk for injury. Although self-care deficit and dysfunctional grieving can be associated with AIDS, they don't take precedence for a client with AIDS-related dementia. Because CNS deterioration results from infection--not altered tissue perfusion--Ineffective cerebral tissue perfusion isn't an appropriate diagnosis.
