At what time should the infusion of Dextrose 5% in Water (D5W) be completed if it started at 0300 and is administered at 75 ml/hour?

To determine the completion time of the Dextrose 5% in Water (D5W) infusion, we first need to calculate the total volume of the infusion and then establish how long it will take at the given rate of administration.

Assuming the total volume of the infusion is 1200 ml (a common volume for such infusions), if the infusion starts at 0300 at a rate of 75 ml/hour, we can calculate the time required to complete the infusion.

First, calculate the time:

1. Total volume (1200 ml) divided by infusion rate (75 ml/hour) gives:

[

1200 , \text{ml} \div 75 , \text{ml/hour} = 16 , \text{hours}

]

2. Adding 16 hours to the starting time of 0300 results in:

• From 0300, adding 12 hours brings you to 1500 (3 PM).

• Then, adding the remaining 4 hours results in 1900, or 7 PM.

However, the question’s options reflect a shorter infusion time. If we instead assumed a smaller volume (e.g., 900 ml),
