Domain 1: Clinical Data Management Fundamentals
1. The primary role of a Clinical Data Manager (CDM) is to:
A. Recruit study subjects
B. Ensure accuracy, completeness, and integrity of clinical trial data
C. Monitor adverse events
D. Perform statistical analysis
Answer: B
Explanation: CDMs are responsible for data quality, integrity, and compliance
throughout the clinical trial lifecycle.
,2. Which phase of a clinical trial typically generates the largest volume of
data?
A. Phase I
B. Phase II
C. Phase III
D. Phase IV
Answer: C
Explanation: Phase III trials involve large patient populations and multiple sites,
producing the most data.
3. A Clinical Data Management Plan (DMP) should be finalized:
A. After database lock
B. Before study initiation
C. After study closeout
D. During statistical analysis
Answer: B
Explanation: The DMP must be completed before data collection begins to
guide all CDM activities.
4. Which document defines how data discrepancies will be handled?
A. Protocol
B. Informed consent
C. Data Management Plan
D. Statistical Analysis Plan
Answer: C
Explanation: The DMP specifies discrepancy management, query handling,
and data cleaning procedures.
, 5. The primary purpose of database lock is to:
A. Archive data
B. Prevent further changes to data
C. Export data
D. Validate CRFs
Answer: B
Explanation: Database lock ensures data integrity before statistical analysis
begins.
Domain 2: Case Report Forms (CRFs) & eCRFs
6. A Case Report Form (CRF) is best described as:
A. A regulatory submission document
B. A tool to collect protocol-required data
C. A monitoring report
D. A statistical output
Answer: B
Explanation: CRFs capture all required subject data as defined by the protocol.
7. When designing CRFs, the most important principle is:
A. Collect as much data as possible
B. Collect only protocol-required data
C. Match investigator preference
D. Use complex formats
Answer: B
Explanation: Over-collection increases burden and error risk.
8. Which CRF field type minimizes data entry errors?
