What type of practitioner is NOT allowed to prescribe controlled substances?

In the context of Arkansas law, registered nurses are not authorized to prescribe controlled substances. The regulation of prescribing rights is designed to ensure that only qualified individuals with the necessary education and training can prescribe medications, especially those that are controlled due to their potential for abuse and dependence.

Mid-level practitioners, which may include nurse practitioners and physician assistants, have specific authority under Arkansas law to prescribe controlled substances, provided they meet certain requirements and have a supervisory or collaborative agreement with a physician. Dentists also have the legal authority to prescribe controlled substances within the scope of dental practice, often for pain management or other dental-related issues. Similarly, veterinarians can prescribe controlled substances for the treatment of animals under their care.

The distinction lies within the scope of practice and the legislative framework governing each profession. Registered nurses, without additional qualifications or specific designations as advanced practice registered nurses, do not have the authority to prescribe controlled substances, making this the correct answer in the question presented.
