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

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
