For a patient with a BSA of 1.95, how much drug should be administered if the dose is 40 mg/sq. meter?

• A. 40 mg
• B. 78 mg
• C. 80 mg
• D. 95 mg

Answer: (B)

To determine the correct amount of drug to be administered based on the patient's body surface area (BSA) and the dosage provided, you can use the formula: Dose = BSA (m²) × Dose per square meter In this case, the patient's BSA is 1.95 m², and the prescribed dose is 40 mg/m². Calculating it: Dose = 1.95 m² × 40 mg/m² Dose = 78 mg Thus, the amount of drug that should be administered is 78 mg. This calculation clearly shows how the BSA is utilized to tailor medication dosage to the individual patient, ensuring effectiveness while minimizing potential side effects. Understanding BSA calculations is essential in pharmacy practice, as it allows pharmacists and technicians to provide safe and accurate medication dosing. The choice of 78 mg aligns precisely with the calculation based on the patient's specific BSA and the standardized dosage requirement, ensuring appropriate drug administration.
