A nurse is preparing to administer calcitonin 8 units/kg IM to a client who weighs 165 lb. Available is 200 units/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
To calculate the volume (mL) that the nurse should administer, we can follow these steps:
Convert the weight from pounds to kilograms.
1 lb = 0.453592 kg
165 lb×0.453592 kg/lb≈74.843 kg
Calculate the total dose using the weight and prescribed dose:
Total Dose (units)=Dose per kg×Weight (kg)
Total Dose=8 units/kg×74.843 kg≈598.744 units
Determine the volume using the concentration of the available solution:
Volume (mL)=Total Dose (units)/Concentration (units/mL)
Volume =598.744 units/200 units/mL ≈ 2.994 mL
Therefore, the nurse should administer approximately 3 mL of calcitonin for the 8 units/kg IM dose, rounded to the nearest whole number.
