Q11

Please read the question carefully then answer the question below

Some medications have Individualised doses based on a patient's weight and body surface area (BSA), for children, frail adults, adults: for instance, chemotherapy drugs. This is because many of these drugs are very toxic with a narrow therapeutic range. While you may not calculate these doses, you are required to have an understanding of how to do a calculation using BSA. The units of BSA are per square
millimeter (m2). BSA is calculated from a formula that employs the height and weight.

There are numerous formulas - in use here is the Mosteller formula - one of the most commonly used

Mostella formula used to calculate BSA is 

CASE STUDY

Mrs Jones is a 76yr old woman who is to commence chemotherapy. Her weight is 51kg and her height is 165cm

To calculate BSA of Mrs Jones

use a calculator with a Square root symbot √ 51 X 165 /60 = 1.52 (m²).
Therefore, Mrs Jones's BSA (m²) is 1.52 (m²).

Mrs Jones is ordered Cisplatin (for CA of the bladder) 50mgs / (m² ) as a single IV infusion.

Please calculate how many mgs will be needed using the above BSA for Mrs Jones.
