Certainly! Let's break down the problem step by step.

1. Understanding the Problem:
- We need to administer 1 liter of Lactated Ringers IV fluid over 6 hours.
- We need to find out how many milliliters (mL) will be administered per hour and round it to the nearest whole number.

2. Convert Liters to Milliliters:
- 1 liter is equivalent to 1000 milliliters. Therefore, the total volume of fluid to be administered is 1000 mL.

3. Determine the Time Frame:
- We need to administer the fluid over a period of 6 hours.

4. Calculate the Administration Rate:
- To find out how many milliliters per hour will be administered, we divide the total volume by the total time (in hours).
- [tex]\[ \text{mL per hour} = \frac{\text{Total Volume (mL)}}{\text{Total Time (hours)}} = \frac{1000 \text{ mL}}{6 \text{ hours}} \approx 166.66666666666666 \text{ mL/hour} \][/tex]

5. Round to the Nearest Whole Number:
- We need to round 166.66666666666666 to the nearest whole number.
- The nearest whole number to approximately 166.67 is 167.

So, the rate at which the IV fluid should be administered is 167 mL per hour.

Answer:

167 mL/hour

Explanation:

The first step in this dosage calculation problem is to convert the volume of Lactated Ringer's from liters (L) to milliliters (mL). The prefix milli- reflects one-thousandth of the unit it precedes. Thus, 1 L is equivalent to 1000 mL.

Next, divide this 1000 mL by the duration it is ordered to be infused over, which is 6 hours (hrs).

1000 mL ÷ 6 hr
= 166.66667
≈ 167

The Lactated Ringer's should be administered at a rate of 167 mL per hour, or 167 mL/hr.
