Feedback:
The needle's gauge and length are both important when choosing the correct type for injection. The gauge (G) is the needle's inner diameter (bore), through which medication is administered. The gauge is stated using numbers. A 25-G needle has a very small opening and would be used for subcutaneous or intradermal injections; a 23-G needle, which has a larger bore, may be used for IM injections of more viscous (thicker) liquids; an 18-G needle has a very large bore and may be used for IV injection of large amounts of medication. Needles commonly used range in length from ? to 2 inches. A subcutaneous injection is given with a short needle (usually ? inch in length); an IM injection requires a longer needle, with a larger bore, to ensure delivery into the muscle tissue.
