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:
✅Pruritic facial wheals
🚨 Pruritic wheals (hives) are a hallmark of IgE-mediated allergic reactions
🚨 Facial involvement suggests systemic hypersensitivity, not a mild side effect
🚨 Wheals result from histamine release, causing vasodilation and itching
🚨 This finding is a classic sign of penicillin allergy
✅ High-pitched inspiration
🚨 High-pitched inspiration (stridor) indicates airway narrowing
🚨 It suggests laryngeal edema, a dangerous manifestation of hypersensitivity
🚨 This finding signals potential anaphylaxis, a medical emergency
🚨 Immediate intervention is required when this sign is present
❌ Incorrect Options
❌ Gustatory alterations
❌ Taste disturbances are non-allergic side effects
❌ They do not indicate immune-mediated hypersensitivity
❌ Dental discoloration
❌ Dental staining is associated with tetracyclines, not penicillins
❌ It is not related to allergic reactions
❌ Nausea and anorexia
❌ These are common gastrointestinal side effects
❌ They do not reflect an immune hypersensitivity response
❌ Frequent loose stools
❌ Diarrhea is related to altered gut flora, not allergy
❌ It does not indicate an IgE-mediated reaction
