A primary healthcare provider prescribes 1.5 L of normal saline (NS) to be given over 24 hours for continuous intravenous (IV) infusion to a client who has diarrhea.
What should be the rate of infusion that is required to be set in the infusion pump?

41.7 mL/hr

83.3 mL/hr

20.8 mL/hr

62.5 mL/hr

Answer and Explanation

The Correct Answer is D

To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)

1.5 L = 1500 mL (since 1 L = 1000 mL)

Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.

Correct Answer is A

Explanation

To calculate the gt/min ﬂow rate, we need to determine the total number of drops and divide it by the total time in minutes.

First, let's convert the volume from liters to milliliters:

1 L = 1000 mL

Next, we need to determine the total number of drops. This can be calculated using the drop factor and the volume of the solution:

Total drops = Volume (mL) * Drop factor

= 1000 mL * 15 gt/mL

= 15000 gt

Now, we need to calculate the ﬂow rate in gt/min. We divide the total drops by the total time in minutes: Flow rate = Total drops / Total time (min)

= 15000 gt / 360 min

≈ 41.67 gt/min (rounded to the nearest whole number)

Therefore, the correct answer is:

a. 41.6 gt/min

A. 45 mL/hr B. 60 mL/hr C. 75 mL/hr D. 90 mL/hr

Correct Answer is C

Explanation

To calculate the rate (in mL/hr) at which the IV pump should be programmed to deliver the dose of esmolol, we can use the following formula:

Rate (mL/hr) = (Dose × Patient weight × 60) / (Concentration × Time)

Given:

Dose = 2.5 grams Patient weight = 110 lb Concentration = 250 mL

Time = 1 hour (since the dose is given per hour)

Converting the patient's weight from pounds to kilograms:

Patient weight = 110 lb ÷ 2.2046 = 49.9 kg

Substituting the values into the formula:

Rate (mL/hr) = (2.5 g × 49.9 kg × 60) / (250 mL × 1)

Simplifying the equation:

Rate (mL/hr) = (2.5 × 49.9 × 60) / 250

Rate (mL/hr) = 74.85

Rounding to the nearest whole number, the nurse should program the IV pump to deliver 75 mL/hr.

Therefore, the correct answer is c. 75 mL/hr.
