Which of the following is NOT included in the data expected to be on a patient's clinical record?

The information included in a patient's clinical record should be accurate and verified to ensure the quality of care and maintain legal standards. Unverified information lacks reliability and does not contribute to the clinical assessment or treatment planning process. It can lead to misunderstandings or miscommunications between healthcare providers and can jeopardize patient safety.

In contrast, the date of the last visit, the treating assistant's initials, and the patient's diagnosis are essential components of a clinical record. The date of the last visit helps track the frequency of patient care, the treating assistant's initials provide accountability and a clear record of who has interacted with the patient, and the diagnosis offers critical information regarding the patient's health status and necessary treatment protocols. Therefore, unverified information is the element that would not be included in proper clinical documentation.
