Question

An infusion pump is infsing heparin at a rate of 11.3 mL/hr. The infusion bag hanging has 25,000 units of heparin in 500 mL solution. Calculate the flow rate (units/hr) for these heparin infusions. Round the answer to the nearest whole number.

Answer 1

565 units/hour

Explanation:

As given in question,

rate of infusion of pump = 11.3 mL/hr

amount of heparin infusion bag contains = 25,000 units

amount of solution in infusion bag = 500 mL

Since, 500 mL of solution contains 25000 units of heparin

`\textrm{So, 1 mL of solution will contain heparin of amount}=(25000)/(500)units`

= 50 units

Since, 11.3 mL of solution can flow in 1 hour

So, the heparin contains in 11.3 mL of solution = 11.3 x 50

= 565 units

As, 565 units of heparin can flow in 1 hour so the rate of flow of heparin will be 565 units/hour.
