The healthcare provider prescribes 2 L of 5% dextrose in water (DW) IV to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["21"]
Here's how to calculate the infusion rate (gtt/min) for the nurse to regulate:
1. We know:
Total volume of D5W solution: 2 L (liters)
Infusion time: 24 hours
IV administration set gtt/mL: 15 gtt/mL
2. We need to find the infusion rate in gtt/min.
Steps:
a. Convert liters to milliliters (mL) for better calculation:
1 liter = 1000 mL
Total volume (mL) = 2 L * 1000 mL/L
Total volume (mL) = 2000 mL
b. Convert infusion time from hours to minutes:
Infusion time (minutes) = Infusion time (hours) x Minutes per hour
Infusion time (minutes) = 24 hours * 60 minutes/hour
Infusion time (minutes) = 1440 minutes
c. Calculate the total volume of solution to be infused per minute:
Volume rate (mL/min) = Total volume (mL) / Infusion time (minutes)
Volume rate (mL/min) = 2000 mL / 1440 minutes
Volume rate (mL/min) = 1.389 mL/min (round to nearest hundredth)
d. Finally, calculate the infusion rate in gtt/min:
Infusion rate (gtt/min) = Volume rate (mL/min) x gtt/mL
Infusion rate (gtt/min) = 1.389 mL/min * 15 gtt/mL
Infusion rate (gtt/min) = 20.835 gtt/min (round to nearest whole number as requested)
Therefore, the nurse should regulate the infusion at approximately 21 gtt/min

Correct Answer is ["0.8"]
Explanation
Here's how to calculate the volume the nurse should administer:
Concentration of epoetin alfa: 10,000 units/mL (given on the vial label)
Prescribed dose: 8,200 units
We need to find the volume (in mL) that contains the prescribed dose (8,200 units) of epoetin alfa.
Dosage calculation:
Volume to administer (mL) = Dose (units) / Concentration (units/mL)
Volume to administer (mL) = 8,200 units / 10,000 units/mL
Volume to administer (mL) = 0.82 mL (round to nearest tenth as requested)
Therefore, the nurse should administer 0.8 mL.
Correct Answer is ["12000"]
Explanation
Here's how to calculate the total heparin units the client will receive in 12 hours
Heparin concentration:
The medication is delivered in a 500 mL bag containing 20,000 units of heparin.
Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)
Heparin concentration (units/mL) = 20,000 units / 500 mL
Heparin concentration (units/mL) = 40 units/mL
Infusion rate: 25 mL/hour (given)
Time: 12 hours (given)
We need to find the total number of heparin units delivered in 12 hours.
Total volume delivered in 12 hours:
Volume delivered (mL/hour) x Time (hours) = Total volume delivered (mL)
25 mL/hour x 12 hours = 300 mL
Total heparin units delivered:
Heparin concentration (units/mL) x Total volume delivered (mL) = Total heparin units
40 units/mL x 300 mL = 12,000 units
Therefore, the client will receive 12,000 units of heparin in 12 hours.
