Final answer:
To determine the number of mL to draw up for Oxacillin 500mg IV, divide the total dosage by the concentration of the medication, which is typically given as a ratio or percentage. In this case, if the concentration is 100mg/mL, you would draw up 5 mL of the medication.
Step-by-step explanation:
To calculate the number of mL to draw up for Oxacillin 500mg IV, you need to know the concentration of the medication. This information is typically provided as a ratio or percentage. Once you have the concentration, you can use a simple formula:
Amount of medication (in mg) = Concentration x Volume
For example, if the concentration of Oxacillin is 100mg/mL, you would divide 500mg by 100mg/mL to get the volume:
Volume = 500mg / 100mg/mL = 5 mL
Therefore, you would draw up 5 mL of Oxacillin 500mg IV.
