A nurse is preparing to administer 0.45% sodium chloride (NaCl) 1000 mL IV to infuse over 8 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)
The Correct Answer is ["125"]
-
Identify the given values:
- Total volume = 1000 mL
- Total infusion time = 8 hours
-
Use the formula for infusion rate:
Infusion Rate (mL/hr) = Total Volume (mL) ÷ Total Time (hours)
Infusion Rate = 1000 mL ÷ 8 hours
Infusion Rate = 125 mL/hr
Final Answer:
The nurse should set the IV pump to 125 mL/hr for the 0.45% NaCl solution

Correct Answer is B
Explanation
A. The nurse should not withhold the dose without consulting the provider, especially with a low potassium level.
B. A client who is receiving diuretic therapy may lose potassium through urine and develop hypokalemia, which is a low level of potassium in the blood. Hypokalemia can cause cardiac arrhythmias, muscle weakness, and fatigue. The normal range of serum potassium is 3.5 to 5.0 mEq/L. A serum potassium level of 3.2 mEq/L indicates mild hypokalemia and requires potassium supplementation
C. While it's important to verify lab results, the nurse should first administer the prescribed dose of KCL since the patient has mild hypokalemia.
D. This is important but it may delay the treatment of hypokalemia and increase the risk of complications.
