A 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 nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["22ml\/hour"]
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).

Correct Answer is ["2.5 tablets per day"]
Explanation
The client weighs 172 pounds which is equivalent to 78.02 kg (1 kg = 2.20462 pounds).
The prescription for levothyroxine is 1.6 mcg/kg/day, so the client should receive 124.83 mcg of levothyroxine per day (1.6 mcg/kg/day * 78.02 kg).
The medication is available in 50 mcg scored tablets, so the nurse should administer 2.5 tablets per day (124.83 mcg / 50 mcg/tablet).
Correct Answer is ["6 mL\/hour."]
Explanation
To calculate the infusion rate in mL/hour, we can use the following formula:
Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:
200 mg/40 mL = 5 mg/mL
We can calculate the infusion rate as follows:
2 mg/minute x 60 / 5 mg/mL = 24 mL/hour
However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:
200 mL / (120 minutes) = 100 mL/hour
So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:
2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:
X = (2 x 60 x 1) / 5 = 24 mL/hour
So we should program the infusion pump to deliver 6 mL/hour.
