The correct answer is: All of the above

A dental hygienist can perform certain functions when a dentist is not present, and understanding the scope of their practice is essential in the context of Minnesota Dental Laws. When looking at the various functions: Administering local anesthesia is a task that dental hygienists are trained to perform in many jurisdictions, provided they have completed the necessary coursework and obtained additional certification. The legalities regarding administering local anesthesia vary by state, but some allow hygienists to do so under specific conditions without the dentist on-site. Monitoring a patient under nitrous oxide is another function allowed to dental hygienists. They are trained to assess and ensure the safety of patients who are undergoing treatment with nitrous oxide, which is significant for patient care and comfort. This monitoring can be done effectively, as hygienists have the skills to recognize any adverse reactions and act accordingly even in the absence of a dentist. Taking radiographs falls within the responsibilities of a dental hygienist. They are trained to position and expose radiographic images and may do this without the direct supervision of a dentist, as long as they follow established protocols and regulations. Given these aspects, the scope of practice for dental hygienists in Minnesota aligns with the assertion that they can carry out all the functions listed, including administering local anesthesia
