Final answer:
Blanket authorization threatens the need-to-know principle in healthcare.
Step-by-step explanation:
The need-to-know principle is a fundamental concept in healthcare that emphasizes that individuals should only have access to information that is necessary for them to perform their job duties or fulfill their responsibilities.
Out of the options provided, blanket authorization threatens the need-to-know principle. Blanket authorization gives individuals unrestricted access to all information, regardless of whether it is necessary or relevant to their role.
For example, if a healthcare facility implements blanket authorization, it means that all employees will have access to all patient records, regardless of their specific job responsibilities. This can pose a risk to patient privacy and confidentiality.
