MHA 705 Exam 1 Q&A (110 Questions) Health Informatics, DIKW Model, Information Systems 2026

This document contains a structured set of approximately 110 exam-style questions and verified answers covering foundational concepts in health informatics and information science. It includes key topics such as the DIKW (Data, Information, Knowledge, Wisdom) framework, informatics competencies, and the role of technology in managing and transforming healthcare data, as outlined in the early sections of the document. The material further explores essential principles of information systems, including data integrity, data quality, interoperability, and the importance of secure, accurate, and timely information in healthcare decision-making. It also provides detailed explanations of system development methodologies such as the Waterfall model, Rapid Application Development (RAD), Object-Oriented Systems Development (OOSD), and Dynamic Systems Development Method (DSDM), highlighting their relevance in healthcare technology implementation. Additionally, the document examines key roles in knowledge management (e.g., knowledge workers, engineers, and managers), along with concepts such as information processing, information science, and system usability. This content aligns closely with textbooks such as Health Informatics: An Interprofessional Approach and Introduction to Health Informatics, which are commonly used in health administration and informatics programs. This resource is suitable for courses such as Health Informatics, Healthcare Information Systems, Health Administration, and Digital Health. It is particularly valuable for students in MHA programs, health informatics students, and healthcare professionals seeking a strong foundation in informatics principles and information systems for exam preparation and practical application.
