With 30 mEq KCl added to a 1 L bag of normal saline, what fluid rate would provide the patient with 2 mEq KCl/hour?

A. 66.67 mL/hr
B. 100 mL/hr
C. 133.33 mL/hr
D. 150 mL/hr

Answer :

Final answer:

To provide a patient with 2 mEq of KCl per hour from a 1 L bag containing 30 mEq of KCl, the fluid rate should be set to 66.67 mL/hr.

Explanation:

The question asks for the calculation of the fluid rate needed to deliver 2 mEq of KCl per hour when 30 mEq of KCl is added to a 1 L bag of normal saline. To determine the correct fluid rate, we can use the following calculation:

Total KCl in the bag: 30 mEq KCl

Total volume of the bag: 1 L (1000 mL)

Desired delivery rate: 2 mEq KCl/hour

We can calculate the fluid rate by dividing the total volume of the bag by the total amount of KCl and then multiplying by the desired delivery amount:

Fluid rate = (1000 mL / 30 mEq) × 2 mEq/hour = 66.67 mL/hour

Therefore, the correct answer is (option a) 66.67 mL/hr.
