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.)

Answer and Explanation

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.
