MCQ Quiz-Data Standards

MCQ Quiz: Data Standards

by

Data standards are the silent, essential engine of modern healthcare, providing a common language that allows different information systems to communicate. For pharmacists, understanding these standards is key to leveraging technology for safer, more efficient patient care. From RxNorm for medications to HL7 for messaging, these standards are the foundation of interoperability. This quiz for PharmD students will test your knowledge of the critical data standards that make the Electronic Health Record and other informatics tools function.

1. “Interoperability” in health informatics is best defined as the ability of:

  • A computer system to operate without an internet connection.
  • A pharmacist to work in both hospital and community settings.

Answer: Different information systems to exchange and make use of information.

2. The primary purpose of using data standards in healthcare is to:

  • Make information systems more complex and expensive.
  • Ensure that data is consistent, shareable, and understandable across different systems.
  • Increase the amount of time clinicians spend on documentation.
  • Limit patient access to their own health information.

Answer: Ensure that data is consistent, shareable, and understandable across different systems.

3. Which data standard is a comprehensive clinical terminology designed to encode the meanings used in health information, including diagnoses, procedures, and findings?

  • LOINC
  • NDC

Answer: LOINC

5. RxNorm is a standardized nomenclature for clinical drugs. Its primary function is to:
