A nurse is preparing to administer potassium chloride elixir 40 mEq divided into 2 equal doses 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 whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["15"]
Calculate the single dose: 40 mEq / 2 doses = 20 mEq/dose
Calculate the volume: 20 mEq X (5 mL / 6.7 mEq) = 14.93 mL
Round to the nearest whole number: 15 mL

Correct Answer is ["675"]
Explanation
Convert pounds to kilograms: 198 lb ÷ 2.2 lb/kg = 90 kg
Calculate the total daily dose: 15 mg/kg/day X 90 kg = 1350 mg/day
Calculate the dose per administration: 1350 mg/day ÷ 2 doses = 675 mg/dose
Correct Answer is ["50"]
Explanation
Total volume to infuse = 50 mL
Total infusion time in minutes = 20 minutes
Drop factor = 20 gtt/mL
Drip rate (gtt/min) = (Total volume in mL) X (Drop factor) / (Total infusion time in minutes)
= 50 mL X 20 gtt/mL / 20 minutes = 50 gtt/min
