Final answer:
In the assembly of an anesthetic syringe, the anesthetic cartridge is loaded first to avoid contamination and prepare the syringe for effective delivery of the medication.
Step-by-step explanation:
During the loading of an anesthetic syringe, the anesthetic cartridge is loaded first. This is because the cartridge contains the anesthetic solution that will be administered to the patient. The syringe is prepared by first inserting the anesthetic cartridge into the barrel of the syringe. After the cartridge is in place, the needle is then attached, and finally, the plunger is inserted. This sequence ensures that the anesthetic does not become contaminated and that the syringe is ready to deliver the medication effectively.
