A nurse is preparing to administer potassium chloride elixir 40 mEq divided into 2 equal doses every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) ​​​​​​

Order: Potassium chloride elixir 40 mEq divided into 2 equal doses every 12 hours Supply: 6.7 mEq/5 mL Divide total daily dose into 2 doses: 40 mEq ÷ 2 = 20 mEq per dose Set up proportion to find volume for 20 mEq: 6.7 mEq : 5 mL = 20 mEq : X mL Cross-multiply: 6.7 × X = 20 × 5 6.7X = 100 X = 100 ÷ 6.7 X ≈ 14.93 Round to the nearest whole number: 15 mL
