Explanation
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 ["28"]
Explanation
Let's calculate the dosage step-by-step:
1. Convert pounds to kilograms:
154 lbs x 2.2 kg = 70 kg
2. Calculate the total dosage:
40 units/kg x 70kg = 2800 units
3. Determine the concentration of heparin in the solution:
25000 units / 250 mL = 100 units/mL
4. Calculate the volume needed:
2800 units / 100 units/mL ≈ 28 mL
