How should the nurse set the infusion pump for a 0.9% sodium chloride solution of 750 mL to infuse over seven hours?

• A. 110 mL/hr
• B. 107 mL/hr
• C. 100 mL/hr
• D. 120 mL/hr

Answer: (B)

To determine the correct infusion rate for a 0.9% sodium chloride solution of 750 mL to be infused over seven hours, you need to calculate the hourly rate. First, consider the total volume to be infused, which is 750 mL. Next, you need to know the total time for the infusion, which is seven hours. The calculation for the infusion rate is done by dividing the total volume by the total time in hours. The formula used is: Infusion rate (mL/hr) = Total Volume (mL) / Total Time (hours) Substituting in the values: Infusion rate (mL/hr) = 750 mL / 7 hours = 107.14 mL/hr Since infusion rates are typically rounded to the nearest whole number in clinical practice, you would round 107.14 mL/hr to 107 mL/hr. Thus, the most accurate infusion rate to set the pump would be 107 mL/hr, making it the correct answer. This type of calculation is crucial in nursing practice as it ensures that medications and IV fluids are delivered accurately, preventing under- or over-infusion which could lead to complications for the patient.
