The nurse needs to report how many ml remain to be infused for a secondary infusion of 265 ml started 2 hours ago at 85 ml/hour. How many ml are left?

To determine how many milliliters (ml) remain to be infused for the secondary infusion, we first need to calculate how much fluid has already been infused after 2 hours.

The infusion rate is 85 ml/hour. In 2 hours, the total amount infused is calculated as follows:

Total infused = infusion rate × time

Total infused = 85 ml/hour × 2 hours = 170 ml

Now, we start with the initial volume of the secondary infusion, which is 265 ml. To find out how much remains to be infused, we subtract the total amount infused from the initial volume:

Remaining volume = initial volume - total infused

Remaining volume = 265 ml - 170 ml = 95 ml

Thus, there are 95 ml remaining to be infused, making it clear why this option is the correct choice. The calculations confirm that after infusing 170 ml over 2 hours, the nurse would accurately report that 95 ml are left in the secondary infusion.
