Correct Answer: 57
Calculation:
⦁ Convert the client's weight from pounds to kilograms
Weight = 178 lb ÷ 2.2
Weight = 80.9 kg
⦁ Calculate the prescribed dose in mg
Ordered Dose = 140 mg/kg × 80.9 kg
Ordered Dose = 11,326 mg
⦁ Identify the available concentration
Available Concentration = 200 mg/mL
⦁ Calculate the volume to administer
Volume = Ordered Dose ÷ Concentration
Volume = 11,326 ÷ 200
= 56.63 mL
⦁ Round to the nearest whole number
= 57 mL
