Final answer:
The pop-up box is an example of a forcing function in the EHR, used to ensure obligatory tasks like entering DVT prevention orders are completed.
Step-by-step explanation:
The pop-up box you're seeing when admitting a patient using the new Electronic Health Record (EHR) system is an example of A forcing function. A forcing function is a feature built into a system to prevent the user from proceeding with a task until certain conditions are met. In this case, the system requires that orders for DVT prevention are entered before completing the admission process. This helps to ensure that important steps such as DVT prophylaxis are not overlooked and promotes patient safety by reducing the risk of blood clots.
