jewelry
 

Can players wear jewelry if it's completely taped and not visible?
ie watch, bracelets.

No.

As I tell the girls in the catholic youth games I do: No ear rings, no nose rings, no engagement rings.

See rule 3-5-7
Page 30 in the Rule Book.
Sorry I can not copy and paste from NFHS AllAccess

I can.

Taped Earrings ...
 

NFHS rules now have us approaching the head coach instead of the player in the layup line.

Not sure about NFHS, but IAABO, oddly, has two officials approach the head coach, one to inform, and one as a "witness".

2022-23 NFHS Basketball Rules Interpretations
SITUATION 1: An official notices that No. 23 on Team A is wearing earbuds during pregame warm-ups. The official notifies the head coach of Team A that wearing equipment which, in the referee’s judgment, is dangerous or confusing to other players or is not appropriate is not allowed. The official then directs the coach to notify No. 23 that the earbuds need to be removed. No penalties are assessed. RULING: Correct procedure. COMMENT: Officials’ jurisdiction, prior to the game, begins when they arrive on the floor. Officials should use pregame warm-ups and the pregame meeting to identify and address illegal uniforms and equipment. Items that have the potential to increase risk, such as headphones and earbuds, should be corrected when addressed by the official. Illegal items that do not increase risk, such as player equipment that violates the manufacturer’s logo or color rules, must be corrected before the player(s) can enter the game. (2-2-2, 2-4-5, 3-5-1)

And Nothing But The Truth ...
 

From IAABO:

Pregame: Addressing Uniform, Equipment and Apparel Issues

In a Crew of Two, it is recommended that both officials approach the Head Coach. The Referee would lead the discussion, while the Umpire continues to observe both teams in warmups. This provision was added to help protect officials from misunderstandings that can occur when addressing sensitive issues related to uniforms, equipment and apparel.
