The physician orders an IV of 20mEq of potassium chloride in 1000mL of 0.9% NS to infuse over 6 hours. Calculate the flow rate in milliliters per hour. Round to the nearest whole number

Rationale: Step 1: Identify what is given Total IV fluid volume: 1000 mL Total infusion time: 6 hours Step 2: Use the formula for flow rate Flow rate (mL/hr) = Total volume (mL) ÷ Time (hr) Step 3: Substitute the values Flow rate = 1000 mL ÷ 6 hr = 166.67 mL/hr Step 4: Round to the nearest whole number 166.67 mL/hr ≈ 167 mL/hr Final Answer: The nurse should set the IV flow rate to 167 mL/hr.
