单选题 A family member is caring for a client diagnosed with Alzheimer’s disease. Which of the following is most likely to cause the caregiver depression and role strain（）

A、 The caregiver had a close relationship with the client before diagnosis of the illness.
B、 The caregiver has no formal support, such as a visiting nurse or day care worker.
C、 The caregiver understands the full reality of the disease and its inevitable progression.
D、 The caregiver feels unable to control the client and unable to cope with caregiving.

【正确答案】 D

【答案解析】The caregiver who feels unable to control the client’s behavior and unable to cope with the responsibility of caregiving is at the greatest risk for depression and role strain. A close relationship with the client who has Alzheimer’s disease doesn’t place the caregiver at greater risk for role strain and depression. Absence of formal support may cause role strain and depression, but the effect may be mitigated by the caregiver’s coping mechanisms and skills. A deeper understanding of the disease is unlikely to increase role strain or depression.
