A nurse is preparing to administer lactated Ringer’s 250 mL IV to infuse over 15 min. 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 ["1000"]
To calculate the infusion rate, use the formula: mL/hr = (mL x drop factor) / time in minutes
In this case, mL = 250, drop factor = 60 (assuming microdrip tubing), and time = 15 minutes
Plug in the values and simplify: mL/hr = (250 x 60) / 15 - mL/hr = 1000
The nurse should set the IV pump to deliver 1000 mL/hr

Correct Answer is ["0.8"]
Explanation
Convert the client's weight from pounds to kilograms: 183 lb / 2.2 = 83.18 kg
Calculate the dose of furosemide in mg: 0.1 mg/kg x 83.18 kg = 8.32 mg
Calculate the volume of furosemide in mL: 8.32 mg / 10 mg/mL = 0.832 mL
Round the answer to the nearest tenth: 0.8 mL
The nurse should administer 0.8 mL of furosemide via IV bolus.
Correct Answer is ["9.4"]
Explanation
To calculate the dose of acetaminophen liquid, use the formula: Dose (mL) = Ordered dose (mg) / Concentration (mg/mL)
Substitute the values in the formula: Dose (mL) = 300 mg / (160 mg/5 mL)
Simplify and solve for Dose (mL): Dose (mL) = 300 mg x 5 mL / 160 mg
Dose (mL) = 9.375 mL
Round the answer to the nearest tenth: Dose (mL) = 9.4 mL
The nurse should administer 9.4 mL of acetaminophen liquid per dose.
