A nurse teaches an asthmatic client to recognize and avoid exposure to asthma triggers and assists the client's family in implementing specific protection strategies in the home, such as removing carpets and avoiding pets. This nurse's activities can best be described as:

• A. Comprehensive assessment.
• B. Primary prevention.
• C. Secondary prevention.
• D. Treatment intervention.

Answer: (B)

Focusing on preventing disease or its worsening by reducing exposure to risk factors is the main idea here. Teaching an asthmatic client to recognize triggers and helping the family implement home protections—like removing carpets and avoiding pets—cut down on allergen exposure that can trigger symptoms or an attack. These are health-promoting actions aimed at preventing problems before they occur or escalate, which fits primary prevention. It’s not about collecting data (not an assessment), not about identifying disease early (not secondary prevention), and not about treating symptoms or illness (not a treatment intervention).
