A clinical information system contains the following process:

• A. Input, processing, outputs
• B. Input, processing, outputs, analysis
• C. Outputs, inputs, processing, analysis
• D. Processing, inputs, outputs

Answer: (A)

In a clinical information system, data move through a simple input–processing–output cycle. First, data are collected or entered (input). Then the system uses those data to perform operations and transform them into useful information (processing). Finally, the results are presented or delivered to users or other systems (outputs). This sequence captures the fundamental flow: you must have data to process, and you need processed information to output.

The other options introduce extra steps like analysis, or mix up the order, or omit an essential stage. Analysis isn’t part of the basic data-flow steps, and starting with processing implies data exist before input, which isn’t the typical flow. Therefore, the straightforward input–processing–output sequence best represents how a clinical information system operates.
