Please choose the correct ending to complete the given sentence: Health: [header] How to fill a syringe [title] Gather your supplies. [step] You will need the medication vial, syringe-needle unit, alcohol pads, a cotton ball, a band-aid, and a sharps container. [substeps] The alcohol pad is used to wipe the rubber top of the medication container once you remove the outer seal.

Ending1: You may also need to clean the area of the skin where the injection will be administered. The bandage and cotton ball are used to cover the area of the skin where you injected the medication to reduce bleeding. Ending2: Upon removal, the product will disappear and the container should be filled and ready to serve. The needle unit that holds the alcohol pad is used to transport the medicine to the pharmacy to be sent away. Ending3: A good cotton ball will also be used, to prevent the ink from running out of the syringe. An alcohol pen will allow you to write the medication notes on the injection site. Ending4: To nurse the syringe, you will need to put the injection disc into the syringe and open the vial to insert the needle inside. You should insert the needle into the vial, not into the vial, since the syringe may tip out during the insertion process.
