Final answer:
An example of 'competent human intervention' as per the 1989 FDA policy is a physician who decides not to follow a clinical decision support system, as it illustrates a healthcare professional's active decision-making role based on expert judgment in a clinical setting. Option b.
Step-by-step explanation:
The 1989 FDA policy about competent human intervention is illustrated through various practices in medical and healthcare settings.
Competent human intervention implies that a trained professional actively makes decisions or takes action based on their knowledge, skills, and judgment within the healthcare context, thereby intervening in a process that might otherwise be automated or guided by technology or protocols.
The correct choice that represents an example of competent human intervention, according to this policy, is:
b. A physician deciding not to follow the advice of a clinical decision support system
This reflects a situation where a healthcare professional, based on their experience and expertise, exercises their judgment to override or modify the recommendations of a technology-based tool (such as software or a protocol).
This demonstrates the importance of human factors and the role of the professional's discretion in clinical decision-making processes.
So Option b is correct answer.
