A nurse in a mental health unit is preparing to administer a loading dose of fluphenazine 7.5 mg PO to an older adult client who has schizophrenia. Available is fluphenazine elixir 2.5 mg/5 mL. How many mL should the nurse plan to administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["15"]
To determine the correct dosage in mL:
The prescribed dose is 7.5 mg.
The concentration of the elixir is 2.5 mg/5 mL.
Calculate the volume to administer:
Volume (mL) = Desired Dose (mg)÷Concentration (mg/mL)
First, find the concentration in mg/mL:
Concentration=2.5 mg÷5 mL
= 0.5mg/mL
Next, calculate the volume:
Volume = 7.5 mg÷ 0.5 mg/mL
= 15 mL
So, the nurse should administer 15 mL of the elixir.
