Question 1 of 5

A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose? (Round to the nearest tenth.)

Correct Answer: 7.5

Rationale: The correct answer is 7.5 mL.
To determine this, first calculate the total daily dose: 20 mEq/day ÷ 2 doses/day = 10 mEq/dose. Next, find the mL per dose using the available concentration: 10 mEq ÷ 6.7 mEq/5 mL = 7.46 mL, which rounds to 7.5 mL. This ensures the patient receives the correct dose of potassium chloride elixir. Other choices are incorrect because they do not follow the correct calculation or rounding process, leading to potential under or overdosing.
