Example 1: POC charting. A CNA takes vital signs and immediately records them using a mobile tablet that accesses the patient’s medical chart. This prevents them from having to walk out of the room to finish charting information at the central workstation computer. Example 2: POC testing. A CNA uses a glucometer (electric, hand-held device) to collect blood samples and obtain glucose readings right at the bedside instead of having to send samples to a lab.
