5 mL = ? t 1 t 15 mL = ? T 1 T

1 oz = ? mL 30 mL 1T=?t 3 t Find 1/2 oz = ? mL

15 mL 2 t = ? mL 10 mL 1/2 oz = ? T 1 T

t = ? mL 2.5 mL Calibrated Dropper Used to administer small quantities Useful in medication of children and adults and adding small quantities to liquid Dispense eye and ear medications

Pediatric Oral Devices Used with oral medications for children Teach caregivers to use correctly Oral syringes do not have a Luerlock hub and have a cap on the tip (safety issue)

Parenteral Medication Administration The term parenteral refers to any way of giving a drug that does not involve the gastrointestinal (GI) tract. The focus here is on intravenous, intramuscular, subcutaneous, and intradermal medications. There are a variety of syringes used for these types of injections.

Continued Must identify route of administration for injection Administration can be via a syringe and needle or an IV catheter

Must use principles of rounding to ensure safety! 3 mL Syringe Length of needle 1 1 inch for IM Luerlock syringe hub Needle

Barrel Plunger Rubber plunger tip 3 mL syringes Calibrations are measured in tenths

Find: 1.5 mL 2.3 mL 0.8 mL 5 mL and 10 or 20 mL syringes Find: 2.4 mL; 4.4 mL Find: 4 mL; 14 mL Prefilled Single Dose

Syringe Used only once and is discarded Discard any extra medication prior to injection

1 mL Syringe Also known as Tuberculin or TB syringe Used to administer small doses Calibrated in hundredths of a milliliter Can be used to give IM Length of needle is - 5/8 inch dosages of 0.5 mL or less, but you

must change needle to 1-1 inches 1 mL syringe Calibrations measured in hundredths Find 0.05 mL 0.25 mL 0.83 mL

Safety Syringes After use, the needle is protected by a shield Safety syringes are used to protect

from injury Continued Insulin Syringe The insulin syringe is a specially calibrated syringe that is used to measure and administer insulin (ONLY). Instead of measuring in mL, it measures in units. Typically a U-100 syringe is used, which means there are 100 units of insulin per

mL. Always make sure the concentration on the syringe matches the concentration on the insulin vial. Units -100 Insulin Syringe Measurement and administration of units-100 insulin only Do not use for

any other medications 3 Sizes of U-100 Insulin Syringes Insulin Syringe Calibrations are marked in units

Which syringe would you choose for the following doses? Dose: 35 units 5 units 63 units Different Sized Syringes: Calibrations Needless Syringe

Continued Prefilled needleless syringe Used for flushing IV lines
