A medical assistant is documenting a patient's medication allergies. The patient states they are allergic to Penicillin, experiencing 'hives and difficulty breathing' when exposed. This type of reaction is classified as which of the following?

  1. AAnaphylactic reaction
  2. BDrug toxicity
  3. CSide effect
  4. DDrug intolerance
Show answer & explanation

Correct answer: A. Anaphylactic reaction

Hives (urticaria) and difficulty breathing (dyspnea) are classic symptoms of an anaphylactic reaction, which is a severe, life-threatening systemic allergic response.

Why the other options are wrong

  • B. Drug toxicity occurs when the drug level in the body is too high, leading to adverse effects, which are not typically hives and difficulty breathing as an allergic response.
  • C. A side effect is a predictable, non-allergic, often mild, secondary effect of a medication.
  • D. Drug intolerance refers to a lower threshold for the normal pharmacologic effects of a drug, not an immune response like hives or breathing difficulty.

Anaphylaxis

A severe, potentially life-threatening systemic allergic reaction that can involve multiple body systems, often characterized by rapid onset of symptoms like hives, swelling, difficulty breathing, and a drop in blood pressure.

  • Requires immediate medical intervention.
  • Caused by exposure to an allergen.
  • Can be fatal if untreated.
