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.
