What activity allows you to review previous lab results and past visit notes?

The correct choice pertains to the concept of chart review activity. This process involves going over a patient's medical records, which includes previous lab results, visit notes, and other relevant documentation. The purpose of a chart review is to gather comprehensive information about the patient's medical history, current health status, and treatment progress. This allows healthcare providers to make informed decisions regarding ongoing care and management of the patient's conditions.

In chart review activities, healthcare professionals can identify trends in lab results, recognize changes in a patient's condition, and review the notes from past visits to understand the treatment path that has been followed. This practice is crucial for ongoing care, continuity of treatment, and ensuring that all relevant information is considered in the clinical decision-making process.
