The physician orders potassium chloride 20 mEq in 100 mL of D5W to infuse at 10 mEq/hr. The nurse has available 20 mEq in 100 mL. What is the rate in mL/hr?

Answer :

The infusion rate should be set to 50 mL/hr.

To determine the infusion rate in mL/hr, we need to calculate how many mL correspond to 10 mEq.

Given that the solution contains 20 mEq in 100 mL:

Find the mEq per mL ratio: 20 mEq / 100 mL = 0.2 mEq/mL.

Determine the infusion rate in mL/hr: 10 mEq/hr ÷ 0.2 mEq/mL = 50 mL/hr.

Thus, the infusion rate should be set to 50 mL/hr.
