A. While the loss of a significant other can be a risk factor for suicide, retired older males may have developed coping mechanisms over time that could mitigate the risk. B. While working in a pediatric emergency department can be stressful, it does not necessarily indicate a higher risk for suicide compared to other factors such as personal life stressors or mental health issues. C. Adolescents experiencing significant life changes such as parental divorce are at increased risk for suicide due to the emotional upheaval and lack of coping skills typical of this age group. D. While being a single working mother with three preschool-aged children can be stressful, it does not inherently indicate a higher risk for suicide compared to other factors such as social support, coping mechanisms, and mental health status.
