Which hand hygiene moment should be performed after a body fluid exposure risk?

• A. After a body fluid exposure risk
• B. Before touching a patient
• C. Before a sterile procedure
• D. During a meal

Answer: (A)

After a body fluid exposure risk, hands are most likely to be contaminated with pathogens, so hand hygiene must be done immediately to prevent spreading those microbes to the patient, other surfaces, or yourself. This moment is specifically designed to interrupt transmission right after potential contamination, even if gloves were worn, since gloves can have micro-tears or contamination can occur during removal. The other moments serve different protective purposes—before touching a patient to protect the patient, before a sterile procedure to maintain asepsis—while "during a meal" is not a clinical hand hygiene moment.
