Question

A 1L solution containing 25,000 units of heparin must run at 30mL/hr. How much heparin is administered per hour?

Answer 1

750 units

Explanation:

As given in question,

speed of solution = 30 mL/hr

1 L of solution contains heparin = 25000 units

=> 1000 mL of solution contains heparin = 25000 units

`=>\ \textrm{1 mL of solution contains heparin}\ =\ (25000)/(1000)\ units`

= 25 units

Hence, 30 mL of solutions contains heparin = 30 x 1 mL of solution contains heparin

= 30 x 25

= 750 units

Hence, heparin administered per hour = 750 units
