A primary healthcare provider prescribes 1 liter of 0.9% saline to infuse over 6 hours. What is the infusion rate in mL/hour, rounded to the nearest whole number?

Explanation:
Infusion rate = total volume divided by time. A liter is 1000 mL, infused over 6 hours, so 1000 ÷ 6 ≈ 166.7 mL/hour. Rounded to the nearest whole number gives 167 mL/hour. The other options come from rounding or calculation differences: 166 would be truncating 166.7, 168 would require rounding up more than justified, and 170 is simply off by about 3 mL/hour.
