A client receives a prescription for an intravenous (IV) infusion of 5% Dextrose Injection, USP in 0.45% Sodium Chloride Injection, USP at 55 mL/hour. The IV administration set delivers 10 gtt/mL. The nurse should regulate the drop rate to deliver how many gtts/minute? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["9"]
To calculate the drop rate in gtts/minute, we can use the following formula:
Drop rate (gtts/minute) = (Volume (mL) x Drop factor) / Time (minutes)
Volume to be infused: 55 mL/hour
Drop factor: 10 gtt/mL
Time: 60 minutes/hour
(55 mL x 10 gtt/mL) / 60 minutes = 9.17 gtts/minute
We can round this value to the nearest whole number to get 9 gtts/min

Explanation
The healthcare provider prescribes regular insulin 8 units/hour intravenously (IV).
The IV solution contains 100 units of regular insulin in 100 mL of 0.9% normal saline, so the concentration of insulin in the IV solution is 1 unit/mL (100 units / 100 mL).

Correct Answer is ["22"]
Explanation
The client receives a prescription for heparin sodium 20,000 Units in 5% dextrose injection 500 mL to be infused at a rate of 880 units/hour.
The concentration of heparin in the IV solution is 40 units/mL (20,000 units / 500 mL).
Since the healthcare provider prescribes 880 units/hour of heparin, the nurse should program the infusion pump to deliver 22 mL/hour of the IV solution (880 units/hour / 40 units/mL).
