Medication with strength 1 g/2 mL has been ordered at 10 mg/kg. The patient weighs 197 lb. How much should be administered? (If less than 1, round to the nearest hundredth; otherwise, round to the nearest tenth.)
Given
Weight :197lb (0.454*197=89.4kg)
Available :1g/2ml (1g=1000mg) therefore 1000mg=2ml
Order :10mg/kg
When 1kg=10mg
Then 89.4kg=??mg
Cross multiply and divide
=89.4*10/1
=89.4*10
=894mg
When 1000mg=2ml
Then 894mg=??ml
Cross multiply and divide
=894*2/1000
=1788/1000
=1.788
As it is greater than 1 it has to be rounded to the nearest tenth =1.8
Ans:1.8 ml has to be administered
