question 385

Multiple Choice

Rationalize the denominator. Assume that all variables represent nonnegative numbers and that the denominator is not
zero.
-When determining appropriate doses of medication, it is sometimes important to estimate the body surface area (BSA) of a patient. This surface area (in $\mathrm { m } ^ { 2 }$ ) can be approximated using the Mosteller formula BSA $= \left( \frac { h \cdot w } { 3600 } \right) 1 / 2$ where $h$ is the patient's height in centimeters and $w$ is the weight in kilograms. Determine the BSA for a patient with height $172 \mathrm {~cm}$ and weight $90 \mathrm {~kg}$ . Round your answer to two decimal places.

• A) \(4.30 \mathrm {~m} ^ { 2 }\)
• B) \(18.49 \mathrm {~m} ^ { 2 }\)
• C) \(0.03 \mathrm {~m} ^ { 2 }\)
• D) \(2.07 \mathrm {~m} ^ { 2 }\)
