A nurse is caring for a client who presents to an outpatient treatment center seeking help for gambling. After performing an intake assessment, the nurse should identify which of the following statements by the client as a sign of a gambling addiction?

A. "I have had bipolar disorder for over 10 years." While mental health conditions can co-occur with addiction, this statement does not directly indicate gambling addiction. B. "My parents are my support system." This is a neutral statement and does not indicate addiction. C. “I can't sleep at night. I have insomnia." Insomnia may occur for various reasons and is not diagnostic of gambling addiction. D. "My wife left me. I lost my job and had to file for bankruptcy." Financial ruin and personal losses are strong indicators of gambling addiction.
