Body Surface Area Calculations

Front

What is Body Surface Area (BSA)?

Back

Body Surface Area (BSA) is a measurement used to estimate the total surface area of the human body, often used in medical settings to calculate drug dosages and medical treatments.

Front

How is Body Surface Area (BSA) calculated for adults?

Back

BSA can be calculated using the Du Bois formula: BSA (m²) = 0.007184 × height (cm)⁰.725 × weight (kg)⁰.425.

Front

What is the significance of BSA in medication dosing?

Back

BSA is significant in medication dosing as it provides a more accurate estimation of drug requirements based on the patient's body size, especially in chemotherapy and other treatments.

What is the formula to convert pounds to kilograms?

Back

To convert pounds to kilograms, divide the weight in pounds by 2.2046.

Front

What is the formula to convert inches to centimeters?

Back

To convert inches to centimeters, multiply the height in inches by 2.54.

Front

If a patient has a BSA of 1.5 m² and the medication dose is 10 mg/m², what is the total dose?

Back

Total dose = BSA × dose per m² = 1.5 m² × 10 mg/m² = 15 mg.

Front

How do you calculate the volume of medication needed based on concentration?

Back

Volume (mL) = Total dose (mg) / Concentration (mg/mL).

Front

What is the BSA of a patient weighing 180 lbs and 6 feet 2 inches?

Back

The BSA is approximately 2.06 m².

Front

What is the BSA of a patient weighing 70 lbs and 4 feet 5 inches?

Back

The BSA is approximately 0.95 m².

Front

How do you calculate the total amount of drug needed for a patient with a specific BSA?

Back

Multiply the patient's BSA by the drug dosage per square meter (mg/m²).
