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
