Answer:
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.
Step-by-step 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.
