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

Correct Answer is D

Explanation

A. The drip chamber should not be filled completely with blood, as this can cause clotting and occlusion.
B. The blood should not be infused for more than 4 hr, as this increases the risk of bacterial contamination and transfusion reactions.
C. Medications are usually administered separately from blood products to avoid incompatibility.
D. The packed RBCs should be connected by Y tubing to normal saline to prevent hemolysis and maintain fluid balance. This is an expected finding because it allows the nurse to flush the line with normal saline before and after the blood transfusion, and to switch to normal saline in case of a transfusion reaction.
