Explanation

Secondary prevention focuses on early detection and prompt treatment of a disease to halt its progress.
Screening is the primary method used in secondary prevention to identify unrecognized disease in an apparently healthy population.
Screening for depression at a community level aims to find individuals with early symptoms and initiate treatment, which is the definition of secondary prevention.

Option B: Primary prevention aims to stop the disease from ever occurring. Screening does not prevent the initial onset of depression.
Option C: Tertiary prevention focuses on managing an already established, often chronic, disease to prevent complications and disability. Screening is done before the disease is fully established or diagnosed.
Option D: Primordial prevention is a broader level that aims to prevent the emergence of risk factors (e.g., social, economic) that could lead to disease. Screening targets the disease itself, not the underlying societal risk factors.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Levels of Prevention in Community Health as background academic context rather than a clinical decision trigger.
Nurses in community health play a vital role in secondary prevention by organizing and conducting screening programs for conditions like hypertension, diabetes, and depression.
When screening for depression, nurses often use validated tools like the Patient Health Questionnaire-2 (PHQ-2) for an initial screen, followed by the PHQ-9 if the initial screen is positive.
A positive screening result is not a diagnosis. It indicates the need for a referral to a qualified mental health professional for a full diagnostic evaluation and treatment plan.

How to Approach the Question

First, identify the key action in the question stem, which is 'screening'.
Recall the definitions of the four levels of prevention: Primordial (prevent risk factors), Primary (prevent disease), Secondary (early detection/screening), and Tertiary (rehabilitation).
Match the action 'screening' to its corresponding level of prevention.
Screening directly aligns with the goal of secondary prevention, which is to detect a disease at its earliest stage.
Eliminate the other options based on their definitions. Primary prevention happens before the disease, and tertiary prevention happens after the disease is well-established.
