In assessing a teenager for depression during an interview, what level of health prevention is the nurse practitioner performing?

The assessment of a teenager for depression during an interview falls under secondary prevention. This level of prevention focuses on early detection and prompt intervention to prevent the progression of a disease or condition. In this case, by assessing for signs and symptoms of depression, the nurse practitioner aims to identify any existing mental health issues early on. This can lead to timely treatment and support, thereby reducing the severity and impact of depression on the teenager's life.

Primary prevention, in contrast, would involve strategies aimed at preventing the onset of depression altogether, such as promoting healthy lifestyles or resilience-building activities. Tertiary prevention refers to efforts to manage and improve the quality of life for individuals with chronic illnesses or conditions, focusing on rehabilitation and reducing complications. The mention of a dropout prevention program is more specific to educational contexts and does not directly fit within the typical structure of health prevention levels. Therefore, the focus on assessing and identifying existing depressive symptoms aligns precisely with the goals of secondary prevention.
