Which statement is a limitation of hospital and clinic records?

• A. They are centralized data across patients
• B. Individuals don't represent any specific population
• C. They have standardized information collected on each patient
• D. Completeness does not depend on physician

Answer: (B)

This question is about data representativeness. Hospital and clinic records come from people who seek care, stay in a hospital, or visit a clinic within a particular system. That means they are not a random sample of the whole population. Some groups are more likely to appear in these records (for example, people with certain illnesses, people who have access to care, or those in a specific geographic area), while others are underrepresented. Because of this, results derived from such records may not generalize to the broader population, which is the key limitation.

The other statements describe properties that aren’t the main limitation: records can be centralized within a system and can have standardized fields, and data completeness often depends on how thoroughly physicians document care. But these do not capture the fundamental issue that hospital/clinic data may not reflect the population as a whole.
