Which of the following prescriptions would likely be outside the scope of practice for a dentist?

The prescription for atorvastatin would likely be outside the scope of practice for a dentist because atorvastatin is a medication primarily used to manage cholesterol levels and reduce the risk of cardiovascular disease. While dentists are authorized to prescribe certain medications related to oral health, their practice typically focuses on dental issues and associated pain management which would not generally include long-term management of systemic conditions like hyperlipidemia.

In contrast, ibuprofen, amoxicillin, and lidocaine are commonly prescribed by dentists. Ibuprofen is often used for pain relief and inflammation control, amoxicillin is an antibiotic frequently prescribed for dental infections, and lidocaine is used as a local anesthetic during dental procedures. These medications are directly relevant to the procedures and conditions that dentists commonly encounter in their practice.
