A client is being discharged from treatment for addiction to cocaine. Which statement made by the client would cause the most concern for the nurse?

A. “I’m not very comfortable with being alone yet." While this statement reflects a challenge, it does not directly suggest a risk of relapse. B. "Shooting baskets helps me not think about getting high." This reflects a positive coping mechanism. C. "I am going to take up a new hobby. It's time to start something new." Engaging in new activities is a sign of recovery. D. "I can still hang out with my old friends. I am just not going to use." Associating with friends who use substances significantly increases the risk of relapse.
