Which system allows doctors to enter orders for tests and medications electronically?

• A. Electronic Health Records (EHRs)
• B. 3D Printing in Health Care
• C. CPOE
• D. Interoperability

Answer: (C)

CPOE, or Computerized Physician Order Entry, is the system that lets clinicians place orders for tests, medications, and other services directly within an electronic platform. The key benefit is turning handwritten or verbal orders into a clear, legible, standardized electronic order. Integrated clinical decision support can check for allergies, potential drug interactions, dosing issues, and appropriate testing, which helps prevent errors and speeds up processing. While electronic health records may include order entry as part of their functionality, the defining feature here is the act of entering orders electronically itself, which is what CPOE provides. Interoperability focuses on sharing data between different systems, not the actual ordering process, and 3D printing is used for creating physical models or devices rather than entering orders.
