Which of the following is a potential consequence of anaphylaxis?

Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen. One of the most critical consequences of anaphylaxis is the occurrence of shock and organ failure. During anaphylaxis, the body's immune system releases a surge of chemicals that can cause widespread inflammation and lead to a dramatic drop in blood pressure, known as anaphylactic shock. This state of shock can impair blood flow and oxygen delivery to vital organs, potentially leading to their failure if not treated immediately.

The other options may be associated with different medical conditions or reactions, but they do not encapsulate the most critical consequences of anaphylaxis as effectively as shock and organ failure. Understanding this severe reaction's potential outcomes underscores the importance of prompt recognition and treatment, typically with epinephrine, which can reverse the symptoms and prevent the progression to more severe complications like organ failure.
