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 the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["7.5"]

The correct answer is 7.5 ML

To answer this question, we need to use the formula:

mL to administer = (mEq ordered / mEq available) x mL available Plugging in the values from the question, we get:

mL to administer = (20 mEq/day / 6.7 mEq/5 mL) x 5 mL Simplifying, we get:

mL to administer = (2.99 mL/mEq) x 5 mL Multiplying, we get:

mL to administer = 14.95 mL/day

Since the order is to divide the dose equally every 12 hours, we need to divide the total daily dose by 2:

mL to administer per dose = 14.95 mL/day / 2 Dividing, we get:

mL to administer per dose = 7.475 mL

Rounding to the nearest tenth, we get:

mL to administer per dose = 7.5 mL

Therefore, the nurse should administer 7.5 mL of potassium chloride elixir per dose.
