SYRINGE TYPES. There are four major types of syringes, two of which are designed for administration of specific medications. A standard syringe is most frequently used for IM or subq injections. It is calibrated in milliliters (mL), and some also have minims (m) marked on them as well. Standard syringes are available in 1-, 3-, 5-, 10-, 20-, and 60-mL sizes. You will use the 1-, 3-, and 5-mL syringes for most injections. The tuberculin (TB) syringe is a smaller diameter syringe that holds a total volume of 1 mL and is calibrated in tenths and hundredths of a milliliter as well as sixteenths of a minim, making it an excellent choice for administration of the small and precise volumes of medication required by newborns and infants as well as for the TB skin test for which it was designed. The insulin syringe is similar in size and shape to a TB syringe, but it is calibrated in units of insulin and used only for injecting insulin. Safety: It is no longer considered safe to abbreviate the word unit with “U.” The Joint Commission has included it on the list of Do Not Use Abbreviations. The word “units” must always be spelled out. There are several sizes of insulin syringes that hold different total volumes of 0.3, 0.5, or 1 mL. A standard insulin syringe is 1 mL and holds up to 100 units of insulin. The smaller size that holds only 0.3 mL is best for children who need very small doses of insulin and for people with poor eyesight. The calibrations are printed in a larger font, making it easier for patients with impaired vision to see the numbers more accurately. An insulin syringe usually has a tiny-gauge, short, permanently attached needle. The most common syringe size is

marked for use with U-100 insulin, meaning the strength of the insulin is 100 units of insulin per 1- mL volume. Prefilled syringes are single-dose, ready-to-use, disposable syringe cartridges, some with an attached needle and some to which you must attach a needle, that contain specific dosages of specific medications. The cartridge is loaded into a reusable plastic holder for administration. This drug-delivery device offers various advantages, including ease of use, convenience, and safety. Prefilled injection systems such as Carpuject® (Abbott) and Tubex® (Wyeth-Ayerst) are designed for safe and quick loading and unloading. After using the cartridge, unscrew it from its holder and drop it vertically into a disposal container. Needles The needle is a small, hollow, cylindrical tube with a sharp, beveled cutting-edge tip used to pierce the skin. It is usually made of steel or other metal. Parts of a Needle A hypodermic needle consists of a plastic hub used to attach the needle to the syringe, the bevel, the cannula or shaft, and a safety guard to cover the used needle as soon as it is withdrawn from the patient’s body.

    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.
