How much fluphenazine decanoate should a nurse administer if the available concentration is 25 mg/mL and the ordered dose is 12.5 mg?

How much fluphenazine decanoate should a nurse administer if the available concentration is 25 mg/mL and the ordered dose is 12.5 mg?

• A. 1 mL
• B. 2 mL
• C. 0.5 mL
• D. 0.25 mL

Answer: (C)

To determine the correct volume of fluphenazine decanoate to administer, it’s essential to use the concentration of the medication available. Given that the concentration is 25 mg/mL, you need to find out how many milliliters correspond to the ordered dose of 12.5 mg. To calculate the required volume, you can set up a proportion based on the concentration: 1. First, take the ordered dose of 12.5 mg and divide it by the concentration of the solution (25 mg/mL): \[ \text{Volume} = \frac{\text{Ordered Dose}}{\text{Concentration}} = \frac{12.5 \text{ mg}}{25 \text{ mg/mL}} = 0.5 \text{ mL} \] Thus, administering 0.5 mL will provide the patient with the correct dose of 12.5 mg of fluphenazine decanoate. This calculation is crucial in ensuring proper dosing for patient safety and therapeutic effectiveness.
