When should staff wash their hands to prevent infection in patient care settings?

• A. Before touching a patient
• B. After touching a patient
• C. After using the restroom
• D. After changing dressings and carrying out routine procedures

Answer: (D)

The main idea is that hand hygiene should occur at moments when hands might transfer germs between patients, surfaces, and staff during care. You wash hands after activities that involve contact with patients or their potentially contaminated materials, so you don’t carry organisms to the next task.

The best choice reflects this broad practice: after changing dressings and carrying out routine procedures. Dressing changes and similar procedures expose you to wound exudate, skin microbes, and other contaminants, so cleaning your hands afterward helps prevent transmitting infections to the patient or to the next person you care for.

Washing after touching a patient is important too, but this option specifically highlights the point where contamination is most likely to occur during typical care tasks. Washing after using the restroom is general hygiene, not specific to patient care, and while it’s important, it doesn’t capture the context of routine care activities like dressing changes.
