Which of the following is not listed as a component of a knowledge-based patient monitoring system?

• A. Data acquisition
• B. Presentation
• C. Knowledge base
• D. Database

Answer: (C)

You’re being tested on how knowledge-based patient monitoring systems are typically depicted in architectural terms. In the common view, the main building blocks shown are data acquisition, which collects the patient’s signals; presentation, which delivers the information and alerts to clinicians; and a database, which stores patient data and system state. The knowledge base, while essential to the system’s reasoning, is not usually shown as a separate component in that depiction. Instead, its rules and diagnostic knowledge are embedded within the system’s reasoning layer (and often incorporated into the database or inference engine). Therefore, the item that isn’t listed as its own component in that framework is the knowledge base.
