Question

A patient's IV is infusing at 50 mL/hr and one liter was hung at 1300. When the nurse makes room rounds at 1800, _____ mL should be remaining (or left to be absorbed) in the patient's IV. Answer with a whole number without any decimals. Do not include the unit of measurement in your answer.

Answer 1

To find the remaining IV fluid at 1800 when it infuses at 50 mL/hr from 1300, calculate the total infused over 5 hours (250 mL) and subtract it from 1 liter (1000 mL). The result is 750 mL remaining at 1800.

Step-by-step explanation:

The patient's IV is infusing at a rate of 50 mL/hr, and at 1300 hours, 1 liter (or 1000 mL) was hung. To find out how much will be remaining at 1800 hours, we must calculate the total amount infused between 1300 and 1800 hours which is a period of 5 hours (1800 - 1300 = 5). Therefore, the calculation would be 50 mL/hr × 5 hr = 250 mL. To find the remaining amount, we subtract this from the original volume: 1000 mL - 250 mL = 750 mL. Thus, at 1800 hours, 750 mL should be remaining in the patient's IV.
