Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use pseudonymization
Pseudonymization replaces identifying information with pseudonyms, allowing data utility while protecting privacy. Aggregation reduces granularity but may still reveal identities; encryption secures transport but not the content; obtaining consent is impractical for large datasets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Encrypt the report file
Why it's wrong here
Encryption protects data during transmission but does not address privacy of the data content.
- ✗
Obtain consent from patients
Why it's wrong here
Obtaining consent from all patients is impractical and not always required for de-identified data sharing.
- ✗
Aggregate data at low granularity
Why it's wrong here
Aggregation reduces detail but may not sufficiently protect against re-identification.
- ✓
Use pseudonymization
Why this is correct
Pseudonymization de-identifies data while retaining analytical value, meeting HIPAA requirements for sharing with auditors.
