A physician orders 2000 ml of fluid to be given over a 20-hour period. What flow rate, in ml per hour, is required?

Question

TheoryPractice · Accepted Answer

100 ml/hr. 2000 ml divided by 20 hours equals a flow rate of 100 ml/hr.

Why the other options are incorrect:
• 90 ml/hr: Running at 90 ml/hr would yield only 1800 ml over 20 hours, falling 200 ml short of the order.
• 95 ml/hr: At 95 ml/hr, the total infused would be 1900 ml, still 100 ml below the prescribed volume.
• 105 ml/hr: A rate of 105 ml/hr would deliver 2100 ml, which exceeds the prescribed amount.
• 110 ml/hr: At 110 ml/hr, the patient would receive 2200 ml, significantly above what was ordered.
