Which of the following roles may supervise laboratory operations?

A Medical Technologist is typically the correct choice for supervising laboratory operations. This role involves overseeing various laboratory processes, ensuring the quality and accuracy of test results, managing laboratory personnel, and maintaining compliance with regulatory standards. Medical Technologists have the extensive training and expertise required to handle complex laboratory equipment and procedures, which positions them to supervise both the technical and operational aspects of a laboratory effectively.

In contrast, the other roles listed do not have the same level of involvement or responsibility in laboratory settings. Practical Nurses focus primarily on patient care and nursing tasks rather than laboratory operations. Certified Professional Coders are geared towards coding medical procedures and diagnoses for billing purposes, with minimal interaction with laboratory operations. Health Information Specialists manage medical records and health information but do not typically have roles within the laboratory environment.
