A physician prescribes 5mg of a drug per kilogram of body weight b.i.d. for a patient
weighing 110 lb. How may 0.5g tablets of a drug are required for a 10-day duration?
a) 5
b) 10
c) 20
d) 40 - Answer Convert lbs to kg using proportion.
1 kg/2.2 lbs = X/110lbs
X= 50kg
Calculate mg for course of treatment (per kg):
5 mg/kg x 2 per day x 10 days
= 100 mg/kg
Calculate mg for this 50 kg patient.
100mg/kg = Xmg / 50 kg
X = 5000mg
Convert to g.
5000 mg = 5 g
Divide.
5g / .5g tablets
= 10 tablets
