A nurse is preparing to administer potassium chloride 20 mEq suspension PO daily. The amount available is potassium chloride suspension 10 mEq/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The nurse needs to administer 20 mEq of potassium chloride. Since the suspension is 10 mEq/mL, the nurse will need to administer 20/10 = 2 mL. So, the nurse should administer 2 mL of the potassium chloride suspension.
