Answer 1

Given

Order :Regular insulin

Available: 100 units

Volume :100ml NS

(It means 100 units=100ml NS)

Rate:8 units/hr

First calculate the volume present in 8units

As 100units=100ml

Then 8units=??ml

Cross multiply and divide

=8*100/100

=800/100

=8

Therefore 8units is present in 8ml (i.e.,8units/8ml/hr)

Ans:The pump has to be set at 8ml/hr
