Why shouldn't health care providers wear any body piercing jewelry in a clinical setting?

A. Health care providers can wear body piercing jewelry as long as
the jewelry is not hanging.
B. The jewelry can distract the other health care providers from doing
their job.
C. Health care providers need to put patients at ease, and jewelry can
make some people feel uncomfortable.
D. The jewelry can become loose and fall onto the surgical field,
introducing contaminants to the patient.

A

Explanation:

I was stuck between A and D but I believe the answer is A. I believe jewlery can be worn if it is small and not hanging for example stud earrings. Hanging jewlery can be a threat to the healthcare providers and the patients themselves as it can get tangled up in medical equiptment or in some cases patients can pull on them, harming the provider. D is also somewhat correct but I haven't read anything about jewlery contaminating scenes, the reason I've heard more often is that most jewlery hangs.
