To determine drug dosages, doctors estimate a person’s body surface area (BSA) (in meters squared) using the formula BSA = √ h m

krok68 [10]

Answer:

Step-by-step explanation:

Given that a person’s body surface area (BSA) (in meters squared) using the formula

$BSA =\frac{\sqrt{hm} }{60}$

We are to calculate the rate of change of BSA with respect to mass for a person of constant height h = 180 from m =70 to m =80

For this we calculate BSA for 80 kg and BSA for 70 kg first

Rate of change = $BSA(80)-BSA(70)$

= $\frac{\sqrt{180*80} }{60} -\frac{\sqrt{180*70} }{60} \\=2-1.871\\=0.129$

i.e. rate of change per 10 kg is 0.129

No BSA does not increase more rapidly
