Correct Answer is C

Explanation

To calculate the number of hours it will take to finish the infusion at the current rate, you can use the following formula:

Time (hours) = Volume (mL) / Rate (mL/hr)

In this case, the volume is 1.5 L, which is equivalent to 1500 mL, and the rate is 75 mL/hr.

Now, plug these values into the formula:

Time (hours) = 1500 mL / 75 mL/hr

Time (hours) = 20 hours

So, it will take 20 hours to finish the infusion at the current rate.

A. 250 mL/hr B. 166.67 mL/hr C. 41.67 mL/hr D. 1000 mL/hr

Correct Answer is B

Explanation

To calculate the mL/hr flow rate for a continuous infusion, you can use the following formula:

Flow Rate (mL/hr) = Total Volume (mL) / Total Time (hr)

In this case, the total volume is 2.5 liters, which is equivalent to 2500 mL. The total time is 15 hours.

Flow Rate (mL/hr) = 2500 mL / 15 hr
Flow Rate (mL/hr) = 166.67 mL/hr

So, the mL/hr flow rate for the continuous infusion of 2.5 liters of 0.9% sodium chloride solution over 15 hours is approximately 166.67 mL/hr.
