Injection into the tissues under the dermis of the skin. Injection into the dermis just under the epidermis. Inject medication slowly but smoothly: withdraw needle smoothly, hold syringe steady, apply antiseptic pad, apply gentle pressure at the site. Syringes and needles: type of medication, volume of solution, route of the injection, patients body size. *a syringe consists of a cylindrical barrel, a tip designed to fit the hub of a hypodermic needle, and a plunger. Syringes are single use, disposable, and either luer-lok or non luer-lok. Luer-lok syringe uses a needle that slips onto the tip. A luer-lok syringe uses a needle that twists onto the tip and locks into place. The luer-lok design prevents the accidental removal of a needle from the syringe. *smaller the needle gauge the larger the needle diameter.
