Which type of data collection error occurs when a site coordinator records '120/80' in the diastolic blood pressure field instead of the systolic field?

Accepted Answer

Field placement error

Answer

Placing data in the wrong field is a field placement error, distinct from transcription or omission errors.

Question 2

What is the function of a Data Management Plan (DMP) in relation to data collection?

Accepted Answer

It outlines the processes, tools, responsibilities, and timelines for managing clinical data throughout the trial

Answer

The DMP is the comprehensive document that governs all data management activities including collection methods, timelines, and quality controls.

Question 3

In risk-based data collection, which factor would MOST increase the monitoring intensity for a particular data point?

Accepted Answer

The data point is the primary safety endpoint with direct patient impact

Answer

Data points that are primary safety endpoints with direct patient impact are classified as high-risk and require more intensive monitoring.

Question 4

When a clinical trial uses a central laboratory, which data collection step ensures that lab results are correctly attributed to the right patient and visit?

Accepted Answer

Proper specimen labeling with unique subject and visit identifiers

Answer

Unique specimen labels containing subject ID and visit information are critical to ensuring correct attribution of laboratory results.

Question 5

Which approach to data collection helps ensure that endpoints derived from imaging studies are assessed consistently across all trial sites?
