What size syringe and needle gauge is typically used for subcutaneous injections?

For subcutaneous injections, the typical syringe size is between 0.5 to 3 mL, which is appropriate for delivering smaller volumes of medication that are often used in this route of administration. This volume allows for accurate dosing of medications that are commonly injected subcutaneously, such as insulin or heparin.

The gauge of the needle used for subcutaneous injections should be between 25 to 30 gauge. These finer gauges are suitable for administering medications in the subcutaneous tissue, minimizing discomfort and allowing for easier penetration into the skin without causing trauma to the underlying tissues. A thinner needle gauge is beneficial in reducing pain for patients when injections are given.

When considering the correct answer, it's important that the syringe and needle gauge align with the standard practices in medication administration for subcutaneous injections, maximizing patient comfort and medication efficacy. The other options are mismatched in terms of syringe size and needle gauge for this particular route of injection.
