Final answer:
The certification exam for surgical techs is given by the National Board of Surgical Technology and Surgical Assisting (NBSTSA). The Association of Surgical Technologists (AST) publishes standards for aseptic technique but does not administer the exam.
Step-by-step explanation:
The certification exam for surgical techs is administered by the National Board of Surgical Technology and Surgical Assisting (NBSTSA). The NBSTSA is responsible for the certification of surgical technologists and surgical first assistants. This ensures that individuals meet the national standard in terms of knowledge and proficiency for their roles in the surgical setting. The Association of Surgical Technologists (AST) does not administer the certification exam but plays a significant role in the field by publishing standards for aseptic technique, which includes creating and maintaining a sterile field, a key competency for surgical techs.
