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
Rationale
To calculate: (20 mEq / 40 mEq) × 15 mL = 7.5 mL, which is the correct dose to administer.
