A client is receiving a continuous infusion of IV insulin at 8 mL/hour. Pharmacy makes an infusion of 75 units of regular insulin in 150 mL of Normal Saline for this Institution. How many units per hour is the client receiving? (Use a preceding zero if it applies. Do not use trailing zeros)
The Correct Answer is ["4"]
To calculate the infusion rate in units/hour, we'll follow these steps:
Determine the concentration of insulin in the infusion:
75 units ÷ 150 mL = 0.5 units/mL
Multiply the concentration by the infusion rate:
0.5 units/mL × 8 mL/hr = 4 units/hr

Correct Answer is ["116"]
Explanation
To calculate the IV pump rate, we'll follow these steps:
Determine the required volume of the reconstituted medication:
1,000,000 units ÷ 250,000 units/4 mL = 16 mL
Determine the total volume to be administered:
16 mL (reconstituted volume) + 100 mL (dilution with IV fluid) = 116 mL
Calculate the infusion rate:
116 mL ÷ 1 hour = 116 mL/hour
Correct Answer is ["260"]
Explanation
To calculate the total fluid intake, we'll need to convert all the volumes to a common unit (mL).
Juice:
½ cup = 120 mL (assuming a standard 8-ounce cup)
Gelatin:
3 oz = 90 mL (1 ounce is approximately 30 mL)
Ice pop:
1 oz = 30 mL
Ginger ale:
20 mL
Total intake:
120 mL + 90 mL + 30 mL + 20 mL = 260 mL
