The healthcare provider prescribes epoetin alfa 75 Units/kg subcutaneously for a client who weighs 80 kg. The available vial is labeled Epoetin Alfa 10,000 Units/mL. How many milliliters should the nurse administer to the client for a safe single dose? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.6"]
To calculate the volume of medication to administer, we can use the following formula: Volume = Dose / Concentration
In this case, the dose is 75 Units/kg and the client weighs 80 kg. We can calculate the total dose as follows: 75 Units/kg x 80 kg = 6000 Units
The medication is available in a 10,000 Units/mL vial. We can calculate the volume required as follows: 6000 Units / 10,000 Units/mL = 0.6 mL

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.
Correct Answer is ["56"]
Explanation
Answer: 56 gtt/min.
Rationale:
To calculate the infusion rate in gtt/min, we'll use the following formula:
Infusion Rate (gtt/min) = Volume (mL) / Time (min) x Drop Factor (gtt/mL)
1. Convert volume to mL:
2 liters = 2000 mL
2. Convert time to minutes:
12 hours = 12 x 60 = 720 minutes
3. Plug in the values:
Infusion Rate (gtt/min) = 2000 mL / 720 min x 20 gtt/mL
4. Calculate:
Infusion Rate (gtt/min) ≈ 55.56 gtt/min
5. Round to the nearest whole number:
Infusion Rate (gtt/min) ≈ 56 gtt/min
Therefore, the nurse should regulate the infusion to 56 gtt/min.
