Final answer:
Placing 1 foot on a stool helps the scrub person maintain good posture by redistributing weight and relieving back pressure, in line with maintaining a balanced center of gravity above the hips to avoid back strain.
Step-by-step explanation:
The question asks how a scrub person can maintain good posture. Maintaining good posture is essential for surgical team members who stand for extended periods. Good posture involves standing or sitting in a way that aligns the center of gravity directly above the pivot point in the hips, which helps avoid back strain and damage to disks. Regarding the provided options, placing 1 foot on a stool can help redistribute weight and alleviate pressure on the back, making it a practical approach to maintaining good posture. While other methods might provide temporary relief, they do not promote good posture long-term as effectively as Option C.
