Verified step by step guidance

Begin by understanding the term 'anaphylactic shock'. It is a severe and rapid allergic reaction that can be life-threatening.

Recognize that anaphylactic shock involves multiple systems in the body, primarily affecting the respiratory and cardiovascular systems.

Identify the symptoms of anaphylactic shock, which include difficulty breathing, swelling, hives, and a significant drop in blood pressure.

Understand that anaphylactic shock requires immediate medical attention and is often treated with epinephrine to counteract the severe allergic response.

Note that individuals with known allergies, such as to peanuts, should carry an epinephrine auto-injector and avoid exposure to allergens to prevent anaphylactic shock.
