Final answer:
Give 0.8 mL of Thorazine liquid (15 mg/mL concentration) for the one-time dose of 12 mg.
Step-by-step explanation:
To calculate the amount of Thorazine liquid to give, you can use the following formula:
Volume (mL) = Ordered Dose / Available Concentration
In this case:
Volume (mL) = 12 mg / 15 mg/mL
Volume (mL) = 0.8 mL
Therefore, you would give 0.8 mL of Thorazine liquid for the one-time dose of 12 mg.
