ATI Med surg exam 1A Proctored Exam ( 42 Questions)
Question 1 of 42 :
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
To determine the mL/hr rate for the IV pump, we need to calculate the infusion rate of the
potassium chloride solution. Given:
Potassium chloride concentration: 40 mEq in 500 mL Infusion rate: 10 mEq/hr
We can set up a proportion to find the mL/hr rate:
(40 mEq / 500 mL) = (10 mEq / x mL) Cross-multiplying the equation:
40 mEq * x mL = 500 mL * 10 mEq Simplifying:
40x = 5000
Dividing both sides by 40:
x = 5000 / 40
x ≈ 125
Therefore, the nurse should set the IV pump to deliver approximately 125 mL/hr.
