Correct Answer is ["2.4"]
Explanation
Desired dose = 4,780 IU
Determine the available concentration for IV use after reconstitution:
Available concentration = 10,000 IU / 5 mL
= 2,000 IU/mL
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (IU) / Available concentration (IU/mL)
= 4,780 IU / 2,000 IU/mL
= 2.39 mL
Round to the nearest tenth:
Rounded volume = 2.4 mL
Correct Answer is ["1.4"]
Explanation
Convert the client's weight from pounds to kilograms:
Weight (kg) = Weight (pounds) / 2.2 pounds/kg
= 190 pounds / 2.2 pounds/kg
≈ 86.36 kg
Calculate the prescribed daily dose in micrograms:
Daily dose (mcg) = Prescribed dose (mcg/kg/day) x Client's weight (kg)
= 5 mcg/kg/day x 86.36 kg
≈ 431.8 mcg
Calculate the volume to administer in mL:
Available concentration = 480 mcg / 1.6 mL
= 300 mcg/mL
Volume to administer (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
= 431.8 mcg / 300 mcg/mL
≈ 1.439... mL
Round to the nearest tenth:
Rounded volume = 1.4 mL
