Question

what is the universal precaution when working in a healthcare facility? do not discriminate against patients, especially those suspected of infectious diseases. treat all human blood and certain body fluids as if they are infectious. treat only drug addicts as patients with infectious diseases. treat overseas patients with caution because they can bring infectious diseases.

Explanation:

Universal precautions in healthcare focus on preventing the spread of infectious diseases. Treating all human blood and certain body fluids as infectious (regardless of the patient's perceived status) is a key principle. This approach reduces the risk of exposure to pathogens. Discriminating against patients (as in the first and fourth options) is unethical and not part of universal precautions. Treating only specific groups like drug addicts (third option) is also incorrect as it doesn't follow the "all - inclusive" nature of universal precautions.

Answer:

Treat all human blood and certain body fluids as if they are infectious.
