Which of the following is true about the procedures an extern can perform?

The statement regarding an extern performing procedures requiring certification only after meeting eligibility requirements is accurate because training and oversight are critical components of chiropractic education and practice. In Arizona, externs are permitted to perform certain procedures as long as they have the necessary certifications and meet specific eligibility criteria outlined by the regulatory board. This ensures that the extern has received adequate training and is qualified to perform those tasks safely and effectively under the guidance of a licensed preceptor.

This structure is designed to protect patient safety and maintain the integrity of chiropractic practice while allowing externs to gain practical experience. Therefore, oversight and regulation of what procedures can be performed by externs ensure compliance with legal and ethical standards within the field.
