NURSING MNEMONIC
Biphasic Reaction May occur several hours after inital attack resolves as secondary or Biphasic and happen hours to several days after initial
DIAGNOSTICS What Will Serum Study Display What Will Identify Cause What Will Confirm Food Allergy Elevated IgE for antigen exposure Skin/RAST test confirms antigen skin pricking test, allergen specific IgE serum level, atopy patch test
Acute Intervention NPO!!!! Benadryl IV, first drug of choice epinephrine, oral diphenhydramine (histamine inhibitor such as rantiidine, cimetidine, or corticosteroids may be indicated-dexamethasone IV
Epinephrine Dosage Child 0.01mg/kg/dose of 1:1000 concentration Epi Pen 0.3mg for children 25kg (55lbs) and above Epi Pen Jr 0.15 for whicren 10-25kg (22-55lbs)

What Should be Available At All Times for Nurse What Access is Priority What Do You Do In Vascular Collapse Patient with Heart Palpitations and Tachycardia laryngoscope, intubation tray, trachestomy kit, code cart Start IV access with Large Bore Needle in at least one site preferably two for meds If vascular collapse administer extra fluids (crystalloids or colloids) and plasma volume expander Heart palpitations and tachycardia are normal in this situation
