What is hypoglycemia?
The extreme, life-threatening form of an allergic reaction that involves multiple body systems and rapidly compromises the ABCs.
What is anaphylaxis?

What is the Right Lower Quadrant (RLQ)?
The three physical assessments that make up the Cincinnati Prehospital Stroke Scale.
What are facial droop, arm drift, and speech?
The classic "Three P's" (polyuria, polydipsia, polyphagia) are the primary early symptoms of this unchecked diabetic state.
What is hyperglycemia (or high blood sugar)?
The primary chemical released by the body's immune system during an allergic reaction, responsible for causing bronchoconstriction and vasodilation.
What is histamine?
The physical signs of a sympathomimetic overdose (like cocaine or methamphetamine) include tachycardia, hypertension, diaphoresis, and this specific pupil presentation.
What are dilated pupils?
Dark, tarry, and extremely foul-smelling stools that indicate an active upper gastrointestinal bleed.
What is melena?

What is syncope?
The deep, rapid breathing pattern that a patient in DKA develops in an attempt to blow off excess acids from their bloodstream.
What are Kussmaul respirations?
To be clinically classified as true anaphylaxis rather than just a severe allergic reaction, the patient must present with respiratory distress and/or this specific cardiovascular compromise.
What is shock (or severe hypotension)?
The acronym SLUDGEM is used to recall the massive parasympathetic signs and symptoms of exposure to this specific category of toxic substances.
What are nerve agents (or organophosphates/cholinergics)?
The physical assessment term for a rigid, board-like abdomen caused by the involuntary contraction of the abdominal wall muscles to protect inflamed internal organs.
What is guarding?
