The healthcare provider prescribes furosemide 120 mg intravenously (IV) for a client with fluid overload. Furosemide is available in a vial labeled 10 mg/mL, and the recommended rate for IV administration is 40 mg/minute. The nurse should administer the medication over what length of time in minutes? (Enter numeric value only.)
The Correct Answer is ["3"]
Here's how to calculate the duration (minutes) for the nurse to administer furosemide:
Prescribed dose: 120 mg furosemide (given)
Recommended rate: 40 mg/minute (given)
We need to find the total time (minutes) required to administer the prescribed dose (120 mg) at the recommended rate (40 mg/minute).
Time (minutes) = Dose (mg) / Rate (mg/minute)
Time (minutes) = 120 mg / 40 mg/minute
Time (minutes) = 3 minutes
Therefore, the nurse should administer the medication over 3 minutes.

Explanation
Here's how to calculate the rate (mL/hour) for the infusion pump:
Heparin concentration:
The medication is available in a 250 mL bag containing 20,000 units of heparin.
Heparin concentration (units/mL) = Total heparin (units) / Volume (mL)
Heparin concentration (units/mL) = 20,000 units / 250 mL
Heparin concentration (units/mL) = 80 units/mL (round to nearest whole number)
Prescribed heparin dose: 1,400 units/hour (given)
We need to find the volume delivered per hour (mL/hour) to achieve the prescribed heparin dose (1400 units/hour) considering the concentration (80 units/mL).
Infusion rate (mL/hour) = Dose (units/hour) / Concentration (units/mL)
Infusion rate (mL/hour) = 1400 units/hour / 80 units/mL
Infusion rate (mL/hour) = 17.5 mL/hour (round to nearest whole number)
Therefore, the nurse should program the infusion pump to deliver approximately 18 mL/hour.
Correct Answer is ["1.3"]
Explanation
Here's how to calculate the volume (mL) of filgrastim the nurse should administer:
Client weight conversion:
Client weight: 176 pounds
Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 176 pounds / 2.205 lbs/kg
Client weight (kg) = 80 kg (round to nearest whole number)
Filgrastim dose per kg:
Dose per kg = 5 mcg/kg (given)
Filgrastim concentration:
The medication vial is labeled 300 mcg/mL. This indicates there are 300 mcg of filgrastim in every 1 mL of solution.
We need to find the volume (mL) containing the prescribed dose (based on weight) of filgrastim (5 mcg/kg) considering the concentration (300 mcg/mL) in the vial.
Total filgrastim dose (mcg): Dose (mcg/kg) x Client weight (kg)
Total filgrastim dose (mcg): 5 mcg/kg * 80 kg
Total filgrastim dose (mcg): 400 mcg
Volume to administer (mL): Total dose (mcg) / Concentration (mcg/mL)
Volume to administer (mL): 400 mcg / 300 mcg/mL
Volume to administer (mL) = 1.33 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 1.3 mL of filgrastim subcutaneously.
