Which of the following constitutes a reason for a DC to be found incompetent?

Fraudulent practice is recognized as a key reason for a Doctor of Chiropractic (DC) to be deemed incompetent. This conduct undermines the trust that is essential in the practitioner-patient relationship and violates ethical standards in healthcare. Engaging in fraudulent practices could include falsifying patient records, misrepresenting treatments, or billing for services not rendered. Such actions not only violate state laws and regulations governing chiropractic practice but also endanger public safety and patient welfare.

Other factors, like certification from another field, miscommunication with clients, or licensing in other states, do not reflect on a DC's professional competency in the same way. Certification from another field can enhance a practitioner’s qualifications, while miscommunication may arise from misunderstandings rather than incompetence. Similarly, holding licenses in multiple states indicates compliance with various state regulations, which generally demonstrates professionalism rather than incompetency.
