Final answer:
The proper order for indexing patient's records for filing is A) Last Name, First Name, Middle Initial. This format is consistent with traditional alphabetical sorting principles used in record keeping and secondary research documentation, which prioritize the last name as the primary sorting criterion.
Step-by-step explanation:
When filing a patient's records, the correct order for potential indexing units is Last Name, First Name, Middle Initial. This method ensures an organized system that allows for easy retrieval of records. It follows the traditional approach of alphabetical sorting which is used not only in medical record keeping but also in various bibliographic entries and documentation organization.
Therefore, the correct sequence from the given options would be A) Last Name, First Name, Middle Initial. This format aligns with most filing systems which prioritize the surname as the primary sorting factor, followed by the first name to distinguish between individuals with the same last name, and finally the middle initial for further differentiation if needed.
For secondary research and other written and published information, the entries would also be organized in a similar fashion. The guidelines suggest that one alphabetize the entries according to authors' last names, and if necessary, use the initials of their first and middle names for additional sorting. Sources should be double-spaced on the entire page.
