Answer :
Final answer:
The nurse will add 7.5 mL of potassium chloride stock solution to the IV bag to achieve the 15 mEq potassium chloride infusion prescribed.
Explanation:
The question is about preparing IV solutions in the context of a medical healthcare setting. Specifically, it is about calculating how much potassium chloride (KCl) to add to an IV bag. In this scenario, there are 15 mEq of KCl to be added to 1,000 mL of D5W (5% dextrose in water) IV solution. The stock solution contains 40 mEq of KCl per 20 mL, which is equal to 2 mEq per mL. Since the prescribed infusion rate is 2 mEq/hr, we are calculating how much KCl the nurse will add to the IV based on the available stock solution concentration.
To add 15 mEq of KCl to the IV bag, we need to divide the amount of KCl needed (15 mEq) by the concentration of the stock solution (2 mEq/mL). This gives us:
15 mEq / 2 mEq/mL = 7.5 mL of KCl stock solution.
Therefore, the nurse will add 7.5 mL of the potassium chloride stock solution to the IV bag to get the required concentration of KCl for infusion.
