Class A violations include which of the following?

Class A violations in veterinary practice typically encompass serious infractions that undermine the integrity of the profession. Intoxication while practicing - where a veterinarian is impaired by drugs or alcohol during the performance of their duties - represents a significant violation of professional ethics and standards. This behavior not only endangers the lives of animals but can also jeopardize the safety of clients and the public, leading to potential harm.

In contrast, minor malpractice and fraudulent advertising would not typically fall under Class A violations, as these infractions may not carry the same level of severity or immediate risk to public safety. Minor malpractice may be addressed in different ways, often depending on its severity and the context, while fraudulent advertising usually has its own regulatory framework that might categorize it differently. Thus, intoxication stands out as a clear violation of both ethical standards and legal guidelines for practitioners.
