You are providing a continuing education session for your EMS department regarding anaphylaxis, as you have just returned from a national conference at which current issues related to this pathology were discussed. During your session, one of your fellow EMS providers asks you how the body can "suddenly" become allergic to something. What is your best response?
A) "The body's white blood cells are uniquely sensitive to certain allergens, and when they are exposed to these allergens for the first time, the body will develop an allergic reaction." B) "It is actually not true that someone 'suddenly' becomes allergic to something. Research shows the person was always allergic to it, but incorrectly assumed he was exposed once before." C) "After a repeat exposure, the newly formed antigens of the body will attack the red blood cells, causing them to die, as well as causing airway closure and bronchoconstriction." D) "After exposure to a new antigen, the body will create antibodies to fight it; these antibodies can be the root cause of the anaphylactic response later."
