Which procedure can a licensed veterinary technician perform under direct supervision of a veterinarian?

A licensed veterinary technician can indeed induce anesthesia under the direct supervision of a veterinarian. This procedure requires a specific skill set and knowledge of anesthetic agents and their effects on various species. The technician must follow protocols and directives set forth by the supervising veterinarian to ensure the safety and well-being of the animal.

In the context of veterinary practice, inducing anesthesia is a critical procedure that must be done carefully to prevent complications. The veterinary technician is trained to monitor the animal's vital signs and adjust anesthetic levels as necessary during the process, making this skill essential in a clinical setting.

The other options listed involve responsibilities that are typically outside the scope of practice for veterinary technicians. Diagnosing animal diseases and prescribing medications both require a veterinary license since they involve higher levels of medical decision-making and legal authority. Performing surgeries also falls under the direct purview of a veterinarian, as these procedures involve significant risks and require comprehensive medical knowledge and experience. Therefore, inducing anesthesia is a procedure that fits well within the veterinary technician's scope of practice when supervised appropriately.
