What are signs of a severe allergic reaction?

A severe allergic reaction, also known as anaphylaxis, can present a variety of symptoms, and all the options provided indicate potential signs of such a reaction. Rash and skin irritation can occur, often manifesting as hives or swelling. Coughing and wheezing are respiratory symptoms that may indicate that a person's airways are narrowing, making it difficult to breathe. The feeling of tightness in the chest is also critical, as it can signal a severe respiratory or cardiovascular reaction that often accompanies anaphylaxis. Therefore, recognizing that all these symptoms can present in severe allergic reactions underscores the importance of swift recognition and response to these signs in a babysitting situation.
