Which of the following pharmaceutical agents can be prescribed?

The correct answer, auto-injector epi pens, is a suitable choice because optometrists are allowed to prescribe medications for the treatment of certain medical conditions, including anaphylaxis, which can be life-threatening. Auto-injector epi pens contain epinephrine and are used to treat severe allergic reactions. The authority for optometrists to prescribe these emergency medications is recognized in various state regulations, including Arizona's, where they have been granted the ability to manage certain urgent care scenarios.

Prescribing oral antifungal medications and oral immunosuppressive agents falls outside the typical scope of practice for optometrists. These medications are generally managed by other specialists, such as dermatologists or rheumatologists, due to the complexities of their usage and the potential side effects that require close monitoring.

IV medications are also not typically within the scope of practice for optometrists. Administering medications intravenously entails a level of training and oversight that is generally reserved for other healthcare providers.

In summary, the choice of auto-injector epi pens aligns with the practices and regulations that govern optometry, enabling practitioners to effectively respond to acute allergic reactions while ensuring patient safety and care.
