A nurse is preparing to administer regular insulin 5 units/hr by continuous IV infusion. Available is regular insulin 100 units in 0.9% sodium chloride 1,000 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["50"]
Calculation:
Determine the total units of insulin available:
Available insulin: 100 units
Determine the total volume of the solution:
Total volume: 1000 mL
Calculate the concentration of the insulin solution in units per milliliter:
Formula: Concentration (units/mL) = Total units / Total mL
= 100 units / 1000 mL
= 0.1 units/mL
Determine the desired dose of insulin per hour:
Ordered dose: 5 units/hr
Calculate the IV pump flow rate in mL/hr:
Formula: Flow rate (mL/hr) = Desired dose per hour (units/hr) / Concentration (units/mL)
= 5 units/hr / 0.1 units/mL
= 50 mL/hr

Correct Answer is ["14"]
Explanation
Calculation:
Determine the total volume to be infused:
Total volume: 250 mL
Determine the total infusion time in minutes:
Infusion time: 3 hours × 60 minutes/hour = 180 minutes
Determine the drop factor of the IV tubing:
Drop factor: 10 gtt/mL
Calculate the total number of drops needed:
Formula: Total drops (gtt) = Total volume (mL) × Drop factor (gtt/mL)
= 250 mL × 10 gtt/mL
= 2500 gtt
Calculate the flow rate in drops per minute (gtt/min):
Formula: Flow rate (gtt/min) = Total drops (gtt) / Total time (minutes)
= 2500 gtt / 180 minutes
≈ 13.89 gtt/min
Round the answer to the nearest whole number:
13.89 gtt/min rounded to the nearest whole number is 14 gtt/min.
Correct Answer is A
Explanation
A. The medication can be used for IV administration: The label clearly states that the medication is for intramuscular or intravenous use only. This means the medication is indeed suitable for IV administration.
B. The medication can be used for up to 14 days after reconstitution: The label specifically mentions that the reconstituted medication should be used within 48 hours. This is less than 14 days.
C. The medication should be reconstituted with 0.9% sodium chloride solution: The label specifies that the medication should be reconstituted with bacteriostatic water for injection, not 0.9% sodium chloride solution.
D. The vial contains a single dose: The label indicates that this is a multiple dose vial, meaning it contains more than one dose.
