Correct Answer is B
Explanation
A. Require a two-factor authentication method when accessing protected health records. – While two-factor authentication improves security, it doesn’t prevent unauthorized browsing of patient records.
B. Require the healthcare provider to document a reason for access prior to granting them entry to a patient's records. – Requiring a documented reason for access would help track and control patient data access, reducing unnecessary or unauthorized views.
C. Implement timed computer screen locks. – Timed locks secure unattended screens but don’t address unauthorized access when logged in.
D. Block Oliver from accessing the electronic health record system. – Blocking Oliver entirely is too restrictive, as he may need access for work-related tasks. Documenting a reason for access is a more balanced approach.
