If a surgical team member refuses to perform a count, the ST should address the concern immediately, explain the importance of accurate counts, and involve the team leader if necessary.
Step-by-step explanation:
If a surgical team member refuses to perform a count during set-up, the Surgical Technologist (ST) should respond by addressing the concern immediately. The ST should inquire about the reason for the refusal and calmly explain the importance of accurate counts for patient safety. It may be necessary to involve the team leader or supervisor if the refusal persists.
