Answer :
Final answer:
The nurse will need to add 7.5 mL of KCl to each litre of IV fluid.
Explanation:
To calculate the amount of KCl to be added to each litre of IV fluid, we need to determine the ratio of mEq per mL. From the given information, we know that the KCl solution contains 20 mEq per 10 mL. We can express this ratio as:
20 mEq / 10 mL
To find the volume of KCl needed for 15 mEq, we can set up a proportion:
20 mEq / 10 mL = 15 mEq / x mL
Cross-multiplying, we get:
20 mEq * x mL = 10 mL * 15 mEq
Simplifying, we have:
x mL = (10 mL * 15 mEq) / 20 mEq
Calculating this, we find that:
x mL = 7.5 mL
Therefore, the nurse will need to add 7.5 mL of KCl to each litre of IV fluid.
