Syringes and Needles

The idea
Injections use a syringe and a needle, and the needle is described by its gauge and its length.
In practice
The right needle depends on the type of injection, the site, and the patient's size and age; the provider's order and the practice's procedure guide the choice.
Where people slip
Read the syringe's markings carefully, because syringes are scaled differently.
