A nurse is preparing to administer aripiprazole 9 mg. IM to a client. Available is aripiprazole injection 9.75 mg/3 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not trailing zero.)
The Correct Answer is ["1.2"]
Determine the concentration of the aripiprazole injection:
Available concentration: 9.75 mg / 1.3 mL
Calculate the volume (in mL) needed for a 9 mg dose:
Use the concentration as a conversion factor:
Volume (mL) = Ordered dose (mg) / Concentration (mg/mL) Volume (mL) = 9 mg / (9.75 mg / 1.3 mL)
Simplify the complex fraction:
Volume (mL) = 9 mg x (1.3 mL / 9.75 mg)
Calculate:
Volume (mL) = (9 x 1.3) / 9.75 = 11.7 / 9.75 = 1.2 mL

Correct Answer is ["2"]
Explanation
Determine the concentration of the chlorpromazine injection:
Available concentration: 25 mg/mL
Calculate the volume (in mL) needed for a 50 mg dose:
Use the concentration as a conversion factor:
Volume (mL) = Ordered dose (mg) / Concentration (mg/mL) Volume (mL) = 50 mg / 25 mg/mL = 2 mL
