Question

which of the following is required to process a prescription for metoprolol (lopressor)?
patient gender
drug enforcement administration (dea) number
route of administration
national provider identifier (npi)

Explanation:

To process a prescription, key details about the medication - related to its administration - are crucial. The route of administration (e.g., oral, injection) determines how the drug will be given to the patient and affects dosing, absorption, etc. Patient gender is not essential for processing the prescription itself. Metoprolol is not a controlled substance so a DEA number isn't required. The NPI is more for identifying providers and not directly needed for processing the specific prescription for this drug.

Answer:

C. Route of administration
