A 10-year-old male is stung by a bee while playing in the yard. He begins itching and develops pain, swelling, redness, and respiratory difficulties. He is suffering from:

  • A. Immunodeficiency
  • B. Autoimmunity
  • C. Anaphylaxis
  • D. Tissue-specific hypersensitivity
Correct Answer: C

Rationale: The correct answer is C: Anaphylaxis. Anaphylaxis is a severe, immediate allergic reaction mediated by IgE. In this scenario, the symptoms of itching, pain, swelling, redness, and respiratory difficulties following a bee sting are indicative of anaphylaxis. Choice A, Immunodeficiency, refers to a weakened immune system's inability to protect the body from infections and diseases, which is not the case here. Choice B, Autoimmunity, involves the immune system attacking healthy cells and tissues by mistake, which is not the mechanism at play in anaphylaxis. Choice D, Tissue-specific hypersensitivity, does not accurately describe the immediate, systemic reaction seen in anaphylaxis.
