A 58-year-old male claims that he is going to kill himself.

The correct answer is B because this patient has multiple major suicide risk indicators : he is directly expressing suicidal intent, he is living alone , has just lost his job , has no support , and expresses hopelessness by saying he sees no purpose in living. In EMS behavioral-emergency assessment, statements suggesting self-harm must be taken seriously, and patients with these risk factors should be considered high risk . EMS educational guidance includes assessing whether the patient has said or done anything indicating possible risk of suicide or violence to self .

Authoritative public health sources also identify social isolation/loneliness , unemployment , and hopelessness/depression-related distress as important suicide risk factors. That makes this patient high risk even before knowing a detailed method or timeline.
