Final answer:
To determine how many milliliters will remain in the syringe after giving one ordered dose of the drug, divide the amount of medication by the concentration of medication. In this case, 0.2 milliliters will remain in the syringe.
Step-by-step explanation:
To determine how many milliliters will remain in the syringe after giving one ordered dose of the drug, we need to do a simple unit conversion. The medication is available in a pre-filled syringe that contains 10 mg/mL. Dr. Garrett has ordered 2 mg of pain medication, so we can use the following equation to find the volume:
Volume (mL) = Amount of medication (mg) / Concentration of medication (mg/mL)
Plugging in the values, we get:
Volume (mL) = 2 mg / 10 mg/mL = 0.2 mL
Therefore, after giving one ordered dose of the drug, 0.2 milliliters will remain in the syringe.
