A client with heart failure (HF) is receiving an IV infusion of 0.9% normal saline 250 mL at a keep-vein-open (KVO) rate of 40 mL/hour. The IV tubing has a mini drip chamber that delivers 60 micro drops/mL. The nurse should regulate the micro drop gravity IV infusion to deliver how many micro drops/minute?
(Enter numeric value only.)
The Correct Answer is ["40"]
A client with heart failure (HF) is receiving an IV infusion of 0.9% normal saline 250 mL at a keep-vein-open (KVO) rate of 40 mL/hour.
The IV tubing has a minidrip chamber that delivers 60 microdrops/mL.
To calculate the infusion rate in microdrops/minute, we need to multiply the infusion rate in mL/hour (40 mL/hour) by the number of microdrops/mL (60 microdrops/mL) and divide by the number of minutes in an hour (60 minutes/hour).
The nurse should regulate the microdrop gravity IV infusion to deliver 40 microdrops/minute (40 mL/hour * 60 microdrops/mL / 60 minutes/hour).

Correct Answer is ["239"]
Explanation
The child receives a prescription for asparaginase 4,780 IU IV.
The vial is labeled "Asparaginase 10,000 IU single-use vial" and for IV use, it should be reconstituted in 5 mL.
Since the child needs 4,780 IU of asparaginase and the vial contains 10,000 IU, the nurse should administer 2.39 mL of medication (4,780 IU / 10,000 IU * 5 mL).
Correct Answer is ["6"]
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.
