Which term describes the set of activities designed to ensure the trial's quality by monitoring compliance and processes, not by data itself?

• A. Quality Control
• B. Source Documents
• C. Quality Assurance
• D. Regulatory Authorities

Answer: (C)

The concept tested here is distinguishing a process- and system-oriented approach from a data-focused one. Quality Assurance refers to the set of activities that ensure trial quality by monitoring and improving how the study is run—the compliance with procedures, proper processes, and overall system effectiveness. It’s proactive and aims to prevent issues by strengthening the way the trial is conducted, through things like SOPs, staff training, process audits, and vendor oversight.

Quality Control, by contrast, is about checking the data itself after collection to identify errors or inconsistencies. Source documents are the original records used to capture data, not the overarching monitoring framework. Regulatory authorities are the bodies that enforce rules, not the ongoing monitoring activities that safeguard trial processes.

So, the term that best describes monitoring compliance and processes to ensure trial quality is Quality Assurance.
