Which of the following may result in disciplinary action for a practitioner?

Obstructing an investigation is a serious violation of professional ethics and state laws governing cosmetology practice. When a regulatory body conducts an investigation into a practitioner’s conduct, cooperation is essential to ensure transparency and accountability. Failing to provide information, withholding cooperation, or engaging in any behavior that hinders the investigation can lead to severe disciplinary action, including suspension or revocation of a practitioner’s license. This action upholds the integrity of the profession and ensures that standards of practice are maintained for the safety and welfare of clients.

In contrast, the other options, while they may raise concerns or reflect poor practice, typically do not carry the same level of risk for disciplinary action as obstructing an investigation. Allowing a client to determine the duration of their service can reflect poor judgment but may not constitute a direct violation of standards. Moving equipment could potentially be a safety concern but is not inherently illegal or unethical. Providing services without an appointment may violate specific salon protocols but is less likely to result in formal disciplinary action compared to obstructive behaviors during an investigation.
