Which area is NOT typically used for subcutaneous injections?

The inner forearm is not typically used for subcutaneous injections, as this area is more commonly reserved for intradermal injections or for certain intravenous access due to its proximity to major blood vessels and nerve pathways. Subcutaneous injections are generally used in areas where there is a sufficient amount of adipose (fat) tissue to ensure proper medication absorption, which is why locations such as the abdomen, scapular area of the back, and upper ventrodorsal gluteal area are preferred. These areas provide a thicker layer of fatty tissue, making them ideal for subcutaneous administration, where the medication can be deposited just under the skin and absorbed into the bloodstream effectively. Therefore, the inner forearm does not meet the criteria typically associated with subcutaneous injection sites.
