A patient is to receive 1500 mg of an anti-infective agent IVPB. Pharmacy sends a vial with instructions to reconstitute with enough sterile water to yield a concentration of 1 Gm/10 mL. After withdrawing the required dose from the vial, Instructions state to further dilute the medication with 100 mL of NSS and infuse over one hour. At what rate will the nurse set the IV pump?
The Correct Answer is ["115"]
To determine the IV pump rate, let’s follow these steps:
Reconstitute the medication:
The concentration after reconstitution is 1 Gm/10 mL.
Since 1 Gm = 1000 mg, the concentration is 100 mg/mL.
Calculate the volume needed for the required dose:
The patient needs 1500 mg.
Using the concentration, calculate the volume: 1500/100= 15 mL
Further dilute the medication:
Add the 15 mL of reconstituted medication to 100 mL of normal saline solution (NSS).
Total volume to be infused = 15 mL + 100 mL = 115 mL.
Set the IV pump rate:
The medication is to be infused over one hour.
Therefore, the IV pump rate is: 115/1= 115 mL/ hr

Correct Answer is ["20"]
Explanation
To calculate the medication dosage, we'll follow these steps:
Determine the required volume:
500 mg ÷ 125 mg/5 mL = 20 mL
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
