K.W. is a patient in a psychiatric ward. His physician has ordered haloperidol 3.5 mg IM stat. If haloperidol is available in a 5 mg/mL vial, what is the volume in mL that will be administered to K.W.?
To determine the volume in mL that will be administered to K.W., we can use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Given that the dose is 3.5 mg and the concentration is 5 mg/mL, we can substitute these values into the formula:
Volume (mL) = 3.5 mg / 5 mg/mL
Simplifying this expression, we find:
Volume (mL) = 0.7 mL
Therefore, the volume in mL that will be administered to K.W. is 0.7 mL.
