If a physician orders 10 mg of a drug and the concentration available is 5 mg/mL, how many mL will the nurse need to administer?

• A. 1 mL
• B. 2 mL
• C. 3 mL
• D. 4 mL

Answer: (B)

To determine the volume of medication the nurse needs to administer, you can use the formula that relates dose, concentration, and volume: Volume (mL) = Dose (mg) / Concentration (mg/mL). In this scenario, the physician has ordered a dose of 10 mg, and the concentration available is 5 mg/mL. Plugging these values into the formula gives: Volume (mL) = 10 mg / 5 mg/mL = 2 mL. This means that to deliver the required dose of 10 mg, the nurse must administer 2 mL of the medication.
