Which practice helps maintain patient confidentiality?

• A. Use of passwords
• B. Bar coding
• C. Graphic sheet
• D. Culture/ethnic background

Answer: (A)

The main idea is controlling who can access patient information. Using passwords directly enforces that only authorized people can log in to electronic health records or other systems, which keeps sensitive data from being viewed by the wrong person. Strong, unique passwords and proper sign-in practices help prevent accidental or intentional disclosures when devices are shared, lost, or left unattended.

Bar coding is about tracking items or patients rather than protecting who can view data. A graphic sheet is a type of document or record format, not a security measure. Culture or ethnic background is sensitive data that needs protection, but confidentiality is maintained through access controls like passwords, not by the data type itself.
