Answer :
Using the Mosteller formula, the BSA for a patient who is 118 cm and 21 kg is approximately 0.83 m2. The recommended medication dosage range based on BSA is then calculated to be 3 mg to 7 mg after rounding to the nearest whole number.
To calculate the Body Surface Area (BSA) of a patient who is 118 cm and 21 kg, we can use the Mosteller formula: BSA (m2) = √((height(cm) x weight(kg))/3600). Therefore, BSA = √((118 x 21)/3600) = √(2478/3600) = √(0.6883) ≈ 0.83 m2. For a medication with a recommendation of 4 mg per m2 to 8 mg per m2, the dosage range for this patient is 0.83 m2 x 4 mg/m2 to 0.83 m2 x 8 mg/m2, which is 3.32 mg to 6.64 mg. After rounding to the nearest whole number, the proper dosage range would be 3 mg to 7 mg.
