Final answer:
The proper term for a nurse entering data using a tablet computer at the patient's bedside is 'point-of-care charting'.
Step-by-step explanation:
The scenario in which a nurse inputs data directly at the patient's bedside using a tablet computer is known as point-of-care charting. This method enables real-time documentation of a patient's condition and the care provided. In comparison, other types of charting such as human-computer charting, freeform charting, and structured charting do not necessarily imply that the documentation is being done at the patient's bedside and can refer to different methodologies or environments for entering patient data. The use of point-of-care charting has become increasingly popular as it improves accuracy and facilitates immediate updates to a patient’s medical record.
