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.
参考答案：D
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.
