3. Your patient weighs 30 kg and is 93 cm. What is the patient's body surface area (BSA)?

A. 0.77 m²
B. 0.88 m²
C. 0.67 m²
D. 0.23 m²

Answer :

Final answer:

Using the Mosteller formula to calculate Body Surface Area (BSA), a patient who weighs 30 kg and is 93 cm tall has a BSA of approximately 0.67 m².

Explanation:

The body surface area (BSA) of a patient can be calculated using different formulas. In pediatrics, the most common one used is the Mosteller formula. According to this formula, BSA is based on the square root of ((height in cm * weight in kg) / 3600). Therefore, if the patient weighs 30 kg and is 93 cm tall, using the Mosteller formula we will compute: BSA = sqrt ((30 * 93) / 3600). This calculation results in a BSA of approximately 0.67 m², making option C the correct answer.
