The furosemide shown here is an example of

A. a medication that is administered IM only: The label on the vial specifies that the medication is for "IM or IV Use." This indicates that the medication can be administered via more than one route. B. a multiple-dose vial: The label clearly states "4 mL Single Dose Vial." This indicates that the vial's contents are meant for one-time use and should be discarded after a single dose has been withdrawn. C. a single-dose vial: The label explicitly indicates that this is a "4 mL Single Dose Vial." This type of vial is intended to be used for one dose and then discarded. The label's "Preservative Free" notation further supports that it is not intended to be stored after opening. D. a medication that needs to be reconstituted: The label lists the contents as "Each mL contains: Furosemide 10 mg... Water for Injection q.s.," which indicates that the medication is already in a sterile liquid solution and is ready for use. It does not come as a powder that requires a liquid diluent to be added before administration.
