A client is admitted for detoxification after a cocaine overdose. The client tells the nurse that he frequently uses cocaine but that he can control his use if he chooses. Which coping mechanism is he using
A. Withdrawal.
B. Logical thinking.
C. Repression.
D. Denial.
参考答案：D
解析：Denial is an unconscious defense mechanism in which emotional conflict and anxiety is avoided by refusing to acknowledge feelings, desires, impulses, or external facts that are consciously intolerable. Withdrawal is a common response to stress, characterized by apathy. Logical thinking is the ability to think rationally and make responsible decisions, which would lead the client to admitting the problem and seeking help. Repression is suppressing past events from the consciousness because of guilty association.
