ATI Med Surg Exam 1A Questions
Question 1 of 5
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:
To determine the mL/hr rate, set up a proportion: (40 mEq / 500 mL) = (10 mEq / x mL). Cross-multiply: 40x = 5000, so x = 5000 / 40 = 125 mL/hr.
Question 2 of 5
A nurse is reviewing a client's laboratory values and discovers the client has a serum potassium of 6.2 mEq/L. Which of the following interventions should the nurse anticipate?
