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?
- AAnaphylactic reaction
- BDrug toxicity
- CSide effect
- DDrug intolerance
Show answer & explanationAnswer & 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.
