- A. Assess level of consciousness
- B. Assess suicide potential

A 45-year-old male client was admitted to a chemical dependency treatment center following legal problems related to alcohol abuse. He states, 'I know that alcohol is a problem for some people, but I can stop whenever I want to. I'm never sick or miss work, and no one can complain about me.' During the initial assessment, the best response by the nurse would be:
- A. The fact is you are an alcoholic or you wouldn't be here.
- B. I understand it took strength to admit yourself to the unit, and I will do my part to help you to stay alcohol-free.
- C. If you can stop drinking when you want to, why don't you stop?
- D. It's good that you can stop drinking when you want to.
Correct Answer: B
Rationale: Direct confrontation initially is nontherapeutic and may result in the client becoming frustrated and wanting to leave. A positive, supportive attitude builds trust, and identifying positive strength raises self-esteem. Offering help allows the client to feel that he is not alone in dealing with problems. Asking the client why or to give an explanation for his behavior puts him in a position of having to justify his behavior to the nurse. Giving approval or placing a value on feelings or a behavior may limit the client's freedom to behave in a way that may displease another. This response may lead to seeking praise instead of progress.

- D. Puppets
