In a healthcare facility, codes are used to:

  1. Enter staff-only areas

  2. Identify patients

  3. Inform staff of emergencies without alarming residents and visitors

  4. Keep records

The correct answer is: Enter staff-only areas

Codes are primarily used for security purposes in healthcare facilities, not for entering staff-only areas. Identifying patients is typically done through their medical records and identification badges. Emergency codes are created to quickly and efficiently alert staff and visitors of an emergency, instead of using codes to inform them indirectly. Keeping records is important in healthcare, but codes are not used specifically for record keeping purposes. Therefore, the correct answer is A.
