If a patient is prescribed 1 L of saline to infuse at 100 mL/hr, how long will it take for the infusion to complete?

To determine how long it will take for a 1 L saline infusion at a rate of 100 mL/hr to complete, you can use the relationship between volume, rate, and time.

First, convert 1 L to mL since the infusion rate is given in mL/hr. There are 1,000 mL in 1 L.

Next, you can calculate the time required for the infusion by dividing the total volume to be infused by the rate of infusion:

[

\text{Time (hours)} = \frac{\text{Total Volume (mL)}}{\text{Infusion Rate (mL/hr)}}

]

Substituting in the numbers gives you:

[

\text{Time (hours)} = \frac{1000 \text{ mL}}{100 \text{ mL/hr}} = 10 \text{ hours}

]

As a result, the correct answer is that it will take 10 hours for the infusion to be completed.

The chosen answer of 8 hours does not align with the calculations, as an infusion rate of 100 mL per hour over a total volume of 1,000 mL logically requires more time than 8 hours
