Practice Question
Which patient assessment findings are clinical indicators of a hypersensitivity reaction to penicillin? (Select all that apply.)
Answer Choices:
Correct Answer:
Pruritic facial wheals
Rationale:
🟦 Penicillin hypersensitivity reactions are immune-mediated responses that can range from mild to life-threatening.
🟦 Pruritic facial wheals indicate urticaria (hives), a classic sign of an allergic reaction.
🟦 High-pitched inspiration suggests laryngeal edema or bronchospasm, which are manifestations of anaphylaxis.
🟦 These findings reflect histamine release and airway involvement, requiring immediate attention.
🟦 Early recognition is critical to prevent airway compromise and cardiovascular collapse.
Gustatory alterations
🟦 Changes in taste are a non-allergic side effect, not a hypersensitivity reaction.
🟦 They do not indicate immune system activation.
Dental discoloration
🟦 Dental staining is associated with tetracyclines, not penicillin.
🟦 It is unrelated to allergic reactions.
Nausea and anorexia
🟦 These are gastrointestinal side effects, not immune-mediated responses.
🟦 They do not signal hypersensitivity.
Frequent loose stools
🟦 Diarrhea reflects GI flora disruption, not allergy.
🟦 It is a common adverse effect, not a hypersensitivity sign.
