Understanding Anaphylaxis and Allergies

What is a common characteristic of anaphylaxis?

What distinction is made between intolerance and allergies?

Which of the following is an example of objective dyspnoea?

Which grade of anaphylaxis indicates respiratory arrest?

What is urticaria commonly known as?

What symptoms are associated with Grade 2 anaphylaxis?

Which term refers to swelling beneath the skin surface?

Which grade of anaphylaxis is characterized by local reactions without changes in vital signs?

Anaphylaxis

Life-threatening allergic reaction affecting airway, breathing, and circulation (ABCs) potentially with skin symptoms
A generalised or systemic hypersensitivity reaction
Some individuals are more predisposed due to genetics or environmental factors

Slide 4 (Definitions)

Urticaria (hives): Red, itchy bumps with rash
Angioedema: Swelling beneath the skin's surface
Objective Dyspnoea: Gasping, increased respiratory rate, decreased oxygen saturation, use of accessory muscles

Grades of Anaphylaxis

Grade 1: Local skin reaction, no vital sign changes
Grade 2 (a/b): Mild/moderate, skin or gastrointestinal tract involvement (e.g., vomiting, diarrhea)
Grade 3 (a/b): Severe, respiratory or cardiovascular issues (e.g., changes in blood pressure, heart rate)
Grade 3C: Severe, respiratory arrest and/or cardiovascular arrest

Intolerances vs. Allergies

Intolerance and allergy terms are sometimes used interchangeably.
Intolerance is an adverse reaction to a substance (e.g., food group, lactose, gluten).
Symptoms are unpleasant and may cause significant discomfort, but are not life-threatening.
Intolerance reactions are often delayed, occurring several hours to even days after ingestion.

This quiz focuses on the life-threatening condition of anaphylaxis, highlighting its definitions, grades, and distinctions from intolerances. Test your knowledge on the various symptoms, genetic predispositions, and the physiological impacts of allergic reactions. Perfect for those studying allergy management and emergency response.
