The bevel is the slanted tip of the needle, designed to facilitate needle insertion and prevent coring (punching out a circular piece of skin) when inserting the needle. Safety: The bevel should always face upward when piercing the skin. The pointed tip entering the skin in front of the bevel limits the degree of tissue injury as the bevel allows for gradual increase in the size of the opening made in the skin. The shaft denotes needle length. Safety: Maintain the sterility of the entire needle. Do not touch any part of it. The needle has a plastic cap or cover that must be removed before use. Safety: To prevent accidental needle sticks with contaminated needles, never recap a used needle. Blood-borne pathogens can be transmitted from the patient to anyone stuck with the contaminated needle. the gauge (G) of a needle refers to the diameter of the needle and is indicated by numbers, typically between 14 G (2.1 mm) and 30 G (0.3 mm). The higher the gauge number, the smaller the diameter of the needle. A 14-G (2.1-mm) needle is a very large-diameter needle, while a 30-G (0.3 mm) needle is very tiny.

Size of gauge depends on - Viscosity of the medication, Route of administration, Size of patient and muscle mass. LENGTH. Needles come in different lengths, typically ranging from ¼ inch to 2 inches (0.64 to 5 cm). The length is measured from the tip of the bevel to the junction of the hub and shaft. The choice of length depends on the weight, amount of fat, and muscle development of the patient; the site of injection; and the route of administration. A subcut injection, which is injected into the layers of subcutaneous fat of an adult, is administered with a shorter needle, between and of an inch (0.9 to 2.2 cm) depending on the patient’s size. For a subcut injection in an infant, you might need a ¼- inch (0.64-cm) needle. For a school-age child, a -inch (1.6-cm) needle would be a likely choice. An IM injection for an adult, injected into the muscular layer below the subcutaneous layer, is administered in the body or largest portion of a muscle and requires a longer needle length, from 1 to 2 inches (2.5 to 5 cm). Children range in size from tiny newborns to adolescents who are similar in size to adults, so the range of needles used for IM injections varies significantly. A newborn might require a -inch (0.9-mm) needle, and a school-age child might require a -to 1-inch (1.6- to 2.5-cm) needle depending on the child’s size. Handling Syringes and Needles o Asepsis is a primary concern when handling syringes and needles. o Safety: It is important to maintain sterility of the appropriate parts of the syringes and needles you work with. As you prepare the syringe, peel the sterile package open and lay the package down with the syringe still resting in one side of the package until you are ready to attach the needle. Safety: Avoid taking the syringe out of the package and laying it on the bare countertop, where you risk contaminating the tip of the syringe.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
