A client is ordered 8 mg of Trifluoperazine orally. 40mg in 6 ml is available. How many millilitres will you administer?

If a client has been ordered 8 mg of trifluoperazine orally, and its presentation is 40 mg in 6 mL, the client should be administered 1.2 ml per dose.

Explanation:

Trifluoperazine is a phenothiazine derivative used as an antipsychotic drug, especially in cases of schizophrenia and some cases of anxiety and major depression.

If Trifluoperazine is available in 40mg/6mL vials, 1.2 mL should be administered when the prescription is for 8 mg. This is calculated as follows:

Trifluoperazine 40 mg 6mL

Indicated dose   8 mg    X

X = (8 X 6)/ 40

X = 48 / 40

X = 1.2 mL

The total volume of drug, according to the indicated dose, is 1.2 mL.
