An elderly woman with COPD who lives alone and engages in risk-taking behavior

A few days ago, an 81-year-old COPD patient was caught smoking by his hospital window while on O2. When warned about the danger, she shrugged, saying, "finally Ill be reunited with my husband." She's widowed, lives alone, and is anxious about her new dependence on oxygen. 

Do you think she has a serious risk of suicide and should have a psych consult?
