A nurse is preparing to administer lactated Ringer's IV to infuse at 60 mL/hr. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (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 ["60"]

To calculate the IV flow rate in gtt/min, you can use the following formula:

Flow rate (gtt/min) = (Volume to be infused (mL) x Drop factor) / Time (min)

In this case, the volume to be infused is 60 mL/hr, the drop factor is 60 gtt/mL, and we want to find the flow rate in gtt/min.

Flow rate (gtt/min) = (60 mL/hr x 60 gtt/mL) / 60 min

Flow rate (gtt/min) = (3600 gtt/hr) / 60 min

Flow rate (gtt/min) = 60 gtt/min

Correct Answer is ["0.9"]

Explanation

  • Convert the client’s weight from pounds to kilograms:

    • 1 kilogram (kg) = 2.2 pounds (lb)
    • Weight in kg = 187 lb / 2.2 = 85 kg

  • Calculate the dose of fentanyl in micrograms (mcg):

    • Dose = 0.5 mcg/kg × 85 kg = 42.5 mcg

  • Determine the volume of fentanyl to administer:

    • Available concentration is 50 mcg/ml
    • Volume (ml) = Dose (mcg) / Concentration (mcg/ml)
    • Volume (ml) = 42.5 mcg / 50 mcg/ml = 0.85 ml

  • Round the answer to the nearest tenth:

    • Rounded volume = 0.9 ml
