A nurse is preparing to administer furosemide 0.1 mg/kg via IV bolus to a client who weighs 183 lb. Available is furosemide 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:
183 lb ÷ 2.2 = 83.18 kg
Rounding to the nearest hundredth, the client’s weight is 83.18 kg.
Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:
0.1 mg/kg × 83.18 kg = 8.32 mg
Rounding to the nearest hundredth, the total medication required is 8.32 mg.
Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:
8.32 mg ÷ 10 mg/mL = 0.832 mL
Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.

Correct Answer is ["2"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. So, the client’s weight in kg is 175 lb ÷ 2.2 lb/kg = 79.55 kg. Step 2 is to calculate the total dose of lorazepam. The total dose is 0.05 mg/kg × 79.55 kg = 3.9775 mg. Step 3 is to calculate the volume to administer. The volume is 3.9775 mg ÷ 2 mg/mL = 1.98875 mL.
So, the correct answer is 2 mL after rounding to the nearest whole number.
Correct Answer is ["48"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the medication dosage is prescribed in mg/kg. Given that 1 kg is approximately 2.2 lb, the conversion is:
210 lb ÷ 2.2 = 95.45 kg (rounded to the nearest hundredth).
Step 2 is to calculate the total amount of medication needed using the formula:
Dose (mg/kg) × Weight (kg) = Total medication needed (mg)
5 mg/kg × 95.45 kg = 477.27 mg (rounded to the nearest hundredth).
Step 3 is to calculate the volume to administer using the formula:
Total medication needed (mg) ÷ Concentration (mg/mL) = Volume to administer (mL)
477.27 mg ÷ 10 mg/mL = 47.73 mL
Rounding off to the nearest whole number, the nurse should administer 48 mL of gentamicin.
