Which of the following symptoms indicate a mild to moderate allergic reaction?

The symptoms that indicate a mild to moderate allergic reaction are characterized by skin-related manifestations and discomfort. Pruritis (itchiness), hives (urticaria), and reddish skin are common responses to allergens that stimulate the immune system. These symptoms arise from the release of histamine and other chemicals by mast cells in the skin, which is a typical response during allergic reactions.

In mild to moderate cases, these symptoms can vary in intensity but often do not progress to more severe systemic reactions. Understanding these symptoms is essential for early identification and management of allergic reactions, ensuring appropriate steps are taken to alleviate the symptoms and prevent progression.

In contrast, the other options present symptoms that are more indicative of conditions outside the spectrum of mild to moderate allergic reactions, focusing instead on different health issues. For example, chest pain, cough, and shortness of breath suggest a more severe allergic reaction, possibly anaphylaxis. Similarly, symptoms like dizziness, lack of appetite, and fatigue are nonspecific and not typically associated with allergic reactions.
