A patient is to receive 1500mg of an anti-infective agent IV. 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 via instructions state to further dilute the medication with 100mL of NS and infuse over one hour At what rate will the nurse set the IV pump?
The Correct Answer is ["115"]
Let's calculate the IV pump rate step-by-step:
1. Determine the total volume to be infused:
The medication is initially reconstituted to a concentration of 1 g/10 mL.
To obtain 1500 mg (or 1.5 g), we need 1.5 g * 10 mL/g = 15 mL.
After further dilution with 100 mL of NSS, the total volume becomes 15 mL + 100 mL = 115 mL.
2. Determine the infusion rate:
The infusion time is given as 1 hour.
To calculate the infusion rate, divide the total volume by the infusion time:
115 mL / 1 hour = 115 mL/hour

Correct Answer is ["538"]
Explanation
1. Convert pounds to kilograms: 1 pound = 0.453592
158 lbs x 0.453592 kg/lb ≈ 71.71 kg
2. Calculate the total daily dosage:
15 mg/kg/day x 71.71 kg ≈ 1075.65 mg/day
3. Calculate the dosage per dose (divided equally every 12 hours):
1075.65 mg/day / 2 doses ≈ 537.83 mg/dose
4. Round to the nearest whole number:
537.83 mg ≈ 538 mg
