A nurse is preparing to administer 40 mEq of potassium chloride in 45% sodium chloride (NaCl) 500 mL IV to infuse 10 mEq/hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
125
Rationale
Calculation: (10 mEq/hr ├À 40 mEq) ├ù 500 mL = 125 mL/hr, ensuring the correct potassium infusion rate.
