A nurse is preparing to administer amphotericin B lipid complex 3.75 mg/kg via intermittent IV bolus to a client who weighs 167 lb. Available is amphotericin B lipid complex 300 mg in 300 mL of dextrose 5% in water. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies.)
The Correct Answer is ["285"]
Calculation:
Convert the client's weight from pounds (lbs) to kilograms (kg):
Formula: Weight in kg = Weight in lbs / 2.2 lbs/kg
= 167 lbs / 2.2 lbs/kg
≈ 75.91 kg
Calculate the total dose of amphotericin B lipid complex needed:
Ordered dose: 3.75 mg/kg
Client's weight in kg: ≈ 75.91 kg
Formula: Total dose (mg) = Ordered dose (mg/kg) × Client's weight (kg)
= 3.75 mg/kg × 75.91 kg
≈ 284.66 mg
Determine the concentration of the available amphotericin B lipid complex solution:
Available amount: 300 mg
Volume of solution: 300 mL
Formula: Concentration (mg/mL) = Total amount (mg) / Total volume (mL)
= 300 mg / 300 mL
= 1 mg/mL
Calculate the volume of solution to administer:
Formula: Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
= 284.66 mg / 1 mg/mL
= 284.66 mL
Round the answer to the nearest whole number:
284.66 mL rounded to the nearest whole number is 285 mL.

Correct Answer is ["25"]
Explanation
Calculation:
Determine the total volume to be infused per hour:
Ordered rate: 100 mL/hr
Determine the drop factor of the IV tubing:
Drop factor: 15 gtt/mL
Calculate the total number of drops to be infused per hour:
Formula: Total drops per hour (gtt/hr) = Total volume (mL/hr) × Drop factor (gtt/mL)
= 100 mL/hr × 15 gtt/mL
= 1500 gtt/hr
Convert the flow rate to drops per minute:
Conversion factor: 1 hour = 60 minutes
Formula: Flow rate (gtt/min) = Total drops per hour (gtt/hr) / 60 min/hr
= 1500 gtt/hr / 60 min/hr
= 25 gtt/min
Correct Answer is ["4"]
Explanation
Calculation:
Determine the desired dose:
Ordered dose: 10 mg
Determine the available concentration of the medication:
Available concentration: 5 mg / 2 mL
Calculate the volume needed to administer the desired dose:
Formula: Volume (mL) = Desired dose (mg) × (Volume of solution (mL) / Available dose (mg))
= 10 mg × (2 mL / 5 mg)
= 20 mL / 5
= 4 mL
