Question

A regular insulin drip at 7 units/hour is ordered for a patient with dka. The IV of 1000 NS contains 50 units of regular insulin. At what rate should the infusion pump be set

Answer 1

Answer: The rate at which the infusion pump should be set is  140 mL/hr

Explanation:

Given that;

the insulin drips at 7 units/hour

The IV is 1000NS  and it contains 50 units of insulin

ratt =?

Now

Rate = (7 units / 1 hour) × (1000 / 50 units )

the concentration is 0.05 units/mL

Rate = 7000 / 50 mL/hr  

Rate = 140 mL/hr.

Therefore The rate at which the infusion pump should be set is  140 mL/hr
