Sugar Highs & Lows
This metabolic disorder is characterized by the total lack of insulin production, typically appearing in childhood, and requires lifelong synthetic insulin.
What is Type 1 Diabetes Mellitus?
This antibody is responsible for "misactivating" during an allergic reaction, directing mast cells to release inflammatory chemicals.
What is the IgE antibody?
This "stress hormone" is essential for maintaining blood pressure and regulating the metabolism of carbohydrates, proteins, and fats.
What is Cortisol?
This high-pitched respiratory sound is a critical red flag for laryngeal swelling and impending airway occlusion.
What is Stridor?
Unlike hypovolemic shock, Neurogenic Shock is characterized by warm, dry skin and this distinct heart rate presentation due to the loss of sympathetic tone.
What is Bradycardia?
A blood glucose level below this threshold (in mmol/L) defines clinical hypoglycemia.
What is 4.0 mmol/L?
The "Classic Triad" of anaphylaxis involves the integumentary system, the cardiovascular system, and this system.
What is the Respiratory System?
Patients with this condition, caused by excess cortisol, may present with a "moon face" and thinning skin.
What is Cushing Syndrome?
A patient exhibiting this type of posturing (extension of the arms and legs) likely has severe damage at the level of the brainstem.
What is Decerebrate Posturing?
The "Widowmaker" is a colloquial term for an occlusion in this major coronary artery, which supplies the anterior wall of the left ventricle.
What is the Left Anterior Descending (LAD) artery?
In Diabetic Ketoacidosis (DKA), the body burns fat for energy, leading to the production of these acids.
What are Ketones?
This phenomenon occurs when a "second wave" of anaphylactic symptoms returns hours after the initial reaction has resolved.
What is a Biphasic Reaction?
This life-threatening emergency is the extreme manifestation of hyperthyroidism, presenting with high fever, tachycardia, and agitation.
What is a Thyroid Storm (or Thyrotoxic Crisis)?
Often mistaken for intoxication, this cluster of symptoms includes headache, confusion, slurred speech, and seizures due to brain glucose deprivation.
What is Neuroglycopenia?
This type of metabolism occurs without oxygen, producing lactate and eventually leading to metabolic acidosis.
What is Anaerobic Metabolism?
This specific respiratory pattern, characterized by deep, labored breathing and fruity breath odor, is a key sign of DKA.
What are Kussmaul respirations?
Often presenting early in a reaction, this skin condition is characterized by hives, flushing, and intense itching.
What is Urticaria?
Primary Adrenal Insufficiency, known by this name, is often caused by an autoimmune attack on the adrenal cortex and leads to salt cravings and hyperpigmentation.
What is Addison Disease?
Patients with Addison’s disease often crave this specific substance due to its loss.
What is Salt?
A patient describing a "tearing" or "ripping" pain radiating to the back, coupled with unequal pulses in the arms, is likely suffering from this.
What is an Aortic Dissection?
Unlike DKA, this condition primarily affects Type 2 diabetics, involves extreme hyperglycemia (>33 mmol/L), but lacks significant ketosis.
What is Hyperosmolar Hyperglycemic Syndrome?
Derived from Greek, this term literally translates to "without protection."
What is Anaphylaxis?
This severe form of hypothyroidism is characterized by hypothermia, bradycardia, and a significant deterioration in level of consciousness.
What is Myxedema Coma?
This respiratory pattern involves oscillating periods of apnea and hyperpnea (fast breathing) and suggests metabolic or structural distress.
What are Cheyne-Stokes Respirations?
These sensory receptors, located in the aortic arch and carotid sinuses, detect falling blood pressure and trigger the sympathetic nervous system.
What are Baroreceptors?
