Calculation
A client is receiving a secondary IV infusion of potassium chloride (KCI) 30 mEq at a rate of 10 mEq an hour. The pharmacy dispenses a 100 mL of 0.9% normal saline (NS) containing KCI 30 mEq. The nurse should program the infusion pump to deliver how many mL/hour (Enter numeric value only. If rounding is required, round to the nearest whole number.)
mL/hr
Explanation & Rationale
Rationale: Given: Total dose of Potassium Chloride: 30 mEq Volume of solution: 100 mL Infusion rate: 10 mEq/hour Step 1: Determine the concentration of Potassium Chloride in the solution: Concentration (mEq/mL) = Total Potassium Chloride (mEq) / Volume of solution (mL) Concentration (mEq/mL) = 30 mEq / 100 mL Concentration (mEq/mL) = 0.3 mEq/mL Step 2: Calculate the infusion rate in mL/hr: Infusion rate (mL/hr) = Infusion rate (mEq/hr) / Concentration (mEq/mL) Infusion rate (mL/hr) = 10 mEq/hr / 0.3 mEq/mL Infusion rate (mL/hr) = 33.33 mL/hr Step 3: Round to the nearest whole number: Infusion rate (mL/hr) ≈ 33 mL/hr
