What are common symptoms of an allergic reaction?

The correct answer encompasses a variety of symptoms that can manifest during an allergic reaction. Allergic reactions can present in several ways, depending on the individual's sensitivity and the nature of the allergen.

Nausea, itchy rashes, and coughing are common early signs of allergies. Itchy rashes often signal a skin allergy, while coughing may indicate respiratory involvement, such as with pollen or pet dander.

Hives and a swollen face are also classic indicators, suggesting more severe allergic responses, such as anaphylaxis. Fever is less common in allergic reactions but can accompany other illnesses that involve allergic responses.

Furthermore, abdominal pains and diarrhea can occur, especially in food allergies, while shortness of breath can result from asthma-like reactions in response to allergens.

By recognizing that all these symptoms contribute to the broader spectrum of allergic reactions, the correct answer shows the importance of understanding how diverse and complex allergic responses can be. Each symptom reflects different bodily responses, reinforcing why it's essential for food service managers to be aware of these potentially life-threatening issues.
