Secondary prevention is used when a nurse

• A. Provides immunizations
• B. Screens for tuberculosis
• C. Educates about proper hygiene
• D. Provides counseling to a client diagnosed with HIV

Answer: (B)

Secondary prevention focuses on early detection of disease to prevent progression and limit transmission. Screening for tuberculosis fits this because it seeks to identify TB in people who may not have symptoms yet, so treatment can start early and stop the disease from advancing or spreading. Immunizations prevent disease from occurring in the first place, which is primary prevention. Educating about proper hygiene is also primary prevention, aiming to reduce risk before disease develops. Providing counseling to a client diagnosed with HIV happens after diagnosis to manage the condition and its complications, which is more aligned with tertiary prevention.
