Hesi Dosage Calculations Care

Hesi Dosage Calculations Care ( 41 Questions)

Question 1 :

A client with dehydration is prescribed a potassium chloride infusion at 10 mEq/hr. Potassium chloride 80 mEq is mixed with 1 liter of normal saline. The nurse should regulate the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)


Correct Answer: ["83 mL\/hour."]


To calculate the infusion rate, we can use the following formula:

Infusion rate = (Total volume of solution x dose of potassium chloride) / time in hours

In this case, the total volume of solution is 1 liter or 1000 mL. The dose of potassium chloride is 10 mEq/hr. Since 80 mEq is mixed with 1 liter of normal saline, we can calculate the dose of potassium chloride in mL/hr as follows:

80 mEq / 1000 mL = 0.08 mEq/mL

10 mEq/hr x 0.08 mEq/mL = 0.8 mL/hr

Therefore, the infusion pump should be regulated to deliver 83 mL/hour.
