In which part of the syringe is medication drawn?

The correct choice for where medication is drawn in a syringe is the barrel. The barrel is the hollow cylindrical part of the syringe that holds the medication. When the plunger is pulled back, it creates a vacuum that allows the medication to be drawn into the barrel.

The design of the barrel is crucial for accurately measuring the dosage of the medication, as it typically has markings or calibrations along its side. This helps healthcare professionals to ensure they are drawing the correct amount of medication.

In contrast, while the plunger is the part that is pushed or pulled to administer or draw the medication, it does not hold the medication itself. The needle hub is the part that connects the needle to the syringe, and the safety shield is a protective cover that prevents accidental needle sticks. Therefore, the barrel is the only part of the syringe that is involved in the actual holding and measurement of the medication during the drawing process.
