Final answer:
The infusion rate for D5W 1000 mL to be administered over 12 hours is approximately 83.33 mL per hour.
Step-by-step explanation:
To calculate the rate at which D5W (dextrose 5% in water) should be infused intravenously per hour, you need to divide the total volume of the IV fluid by the total time it should be infused. The formula is:
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
Given a total volume of 1000 mL of D5W to be infused over 12 hours, the calculation is:
Infusion rate = 1000 mL / 12 hours = 83.33 mL/hour
Therefore, you would administer approximately 83.33 mL of D5W per hour.
