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)
Answer and Explanation

The Correct Answer is ["125"]

  1. Identify the given values:

    • Total volume = 1000 mL
    • Total infusion time = 8 hours

  2. 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 ["56"]

Explanation

To calculate the infusion rate for Ringer's lactate, we need to use the following formula: Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)

Plugging in the values from the question, we get:

Infusion rate (gtt/min) = 500 mL x 20 gtt/mL / 180 min Simplifying, we get:

Infusion rate (gtt/min) = 10000 gtt / 180 min Dividing, we get:

Infusion rate (gtt/min) = 55.56 gtt/min

Since we need to round the answer to the nearest whole number, the final answer is: Infusion rate (gtt/min) = 56 gtt/min
