A mild allergic reaction is characterized by which of the following symptoms?

A mild allergic reaction is primarily characterized by localized symptoms such as skin rashes, urticaria (hives), or mild swelling without significant respiratory involvement or systemic symptoms. The presence of skin rashes, like hives or redness, indicates an immune response that is generally not severe enough to affect breathing or cause other serious health issues.

In contrast, options involving respiratory distress or severe swelling of the tongue are associated with more serious allergic reactions, such as anaphylaxis, which can lead to significant airway compromise and require immediate intervention. Loss of consciousness is another indication of a severe reaction and may signal shock or a significant systemic response. Therefore, skin rashes with no respiratory involvement accurately reflect the nature of a mild allergic reaction, distinguishing it from more severe forms of allergic responses.
