Nursing Informatics Practice Exam 2025 - Free Nursing Informatics Practice Questions and Study Guide

A Clinical Information System is a type of computer-based information system that is used in healthcare. It is designed to help healthcare professionals manage patient's medical and health-related data. An example of a Clinical Information System is an Electronic Health Record (EHR). This is a digital version of a patient's paper chart and contains information about their medical history, diagnoses, medications, lab results, and treatment plans. Option A, Acuity system, is incorrect because it is a type of patient classification system based on the severity of a patient's illness or injury, not a Clinical Information System. Option C, Financial information system, is also incorrect because it is used for managing financial and accounting data, not clinical data. Option D, Security system, is incorrect because it is a type of security system that protects patient data, but is not a Clinical Information System itself. The correct answer, B, Electronic Health Record, is the only option that accurately represents a Clinical Information System.
