A continuous IV infusion of 0.9% saline at 85 mL/hr for 12 hours delivers how many milliliters?

Explanation:
Volume delivered equals flow rate times time. The infusion rate is 85 mL per hour, and it runs for 12 hours, so multiply: 85 × 12 = 1020. The hours cancel, leaving milliliters, so 1020 mL is delivered. The concentration of the solution doesn’t change the calculation of volume here; it only describes what's in the solution, not how much of it is given. Other options would require different durations or rates.
