Which of the following is a valid reason for the physical therapy section to suspend or revoke a physical therapist's license?

The physical therapy section has established regulations to maintain professional standards and ensure the safety and well-being of patients. Each of the provided reasons directly relates to conduct that undermines the integrity of the profession and could pose risks to patients.

Habitual indulgence in controlled substances can impair a physical therapist's judgment and ability to perform safely and effectively, making it a valid reason for suspension or revocation. Such behavior could indicate substance abuse issues that affect the therapist's practice.

A conviction of a felony, particularly if it relates to issues of moral turpitude or involves a violent crime, can also justify disciplinary action. A felony conviction raises concerns about a therapist's reliability, trustworthiness, and ability to comply with the ethical standards expected in healthcare professions.

Obtaining a license by fraud compromises the integrity of the licensing process. License fraud not only reflects dishonesty but also raises questions about the qualifications and competencies of the individual practicing as a physical therapist.

Given that all of these points outline significant breaches of professional conduct, it is clear why the physical therapy section would find any one of these actions sufficient grounds for suspending or revoking a license, supporting the conclusion that all the reasons are valid.
