A nurse is preparing to administer potassium chloride 20 mEq. The amount available is potassium chloride liquid 40 mEq/15 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
7.5 mL
Rationale
Desired dose is 20 mEq, available concentration is 40 mEq/15 mL. mL = (20 mEq ├À 40 mEq) ├ù 15 mL = 7.5 mL.
