Standard Syringe
The 3mL syringe is one of the most common, used for parenteral administration. Have scales calibrated in milliliters. Smaller syringes may have divisions of tenths, two-tenths, or even hundredths of a milliliter.
Safety Syringes
Have the same components as their standard counterparts: however their needles are protected by a plastic shield. These shields help prevent needlestick injury
Prefilled Syringes
Are shipped from the manufacturer filled with a single dose of medication. If the patient is given only a portion of the dose, the rest must be discarded before the medication is administered
Insulin Syringes
Are used only to measure and administer insulin. Measured in units, are unique. Most common strength is U-100; it contains 100 units of per mL.
Tuberculin Syringes
Are used to administer subcutaneous injections as well as the intradermal purifies protein derivative (PPD) skin test that determines if a person has been exposed to tuberculosis. They are small syringes used when small doses of medication, less than 1mL, are administered.
Syringes for Established Intravenous Lines
Administer medication through already established intravenous lines. Although these syringes are needleless, they still have calibrations that must be read carefully
Large-Capacity Syringes
Maximal volume of an IM injection is 3 mL in any one site. Larger volumes of medications may be added to IV infusions or administered IV push, therefore, syringes with 5, 6, 10, and even 12 mL or even more are available
