What volume will be administered if a patient is prescribed 1.5 mg of a drug with a concentration of 0.5 mg/mL?

To determine the volume that will be administered, you can use the formula that relates the dose, concentration, and volume:

Volume (mL) = Dose (mg) / Concentration (mg/mL).

In this scenario, the prescribed dose is 1.5 mg, and the concentration of the drug is 0.5 mg/mL. Plugging these values into the formula:

Volume = 1.5 mg / 0.5 mg/mL = 3.0 mL.

This calculation indicates that in order to deliver the prescribed dose of 1.5 mg using a solution that has a concentration of 0.5 mg/mL, a total volume of 3.0 mL must be administered.

Other choices do not correspond to this calculated volume, as administering less than 3.0 mL would not provide the full prescribed dose, and administering more would exceed the required dosage and potentially lead to an overdose. Thus, the correct answer reflects the accurate calculation based on the drug concentration and prescribed dose.
