The physician orders 250mg every 12hrs The patient weighs 42

The physician orders 250mg every 12hrs. The patient weighs 42kg. The recommended dose is 7mg/kg every 12hrs. What is the maximum safe dose for this patient?

Solution

Recommended dose = 7 mg/kg every 12 hours

7mg dose for patient with weight 1 kg every 12 hours

xmg of dose for patient with weight 42 kg every 12 hours

Hene by equating the equation we get

x/7 = 42/1

x = 42 * 7 = 294mg/kg every 12 hours

Hence the maximum same dose for this patient is 294 mg/kg

Since the physician dose is 250mg every 12hrs which is lesser than maximum safe dose but it will not be therapeutic for man\'s weight
