Definition
Anaphylaxis is a severe systemic allergic reaction that can involve airway compromise, respiratory distress and circulatory collapse.
Why it matters for NCLEX
Anaphylaxis is a high-priority NCLEX scenario because delayed action can rapidly lead to airway obstruction or shock. Students should recognize connected cues rather than treating itching as an isolated symptom.
Clinical example
After an IV antibiotic starts, a patient develops lip swelling, wheezing, oxygen saturation of 88% and blood pressure of 86/48 mmHg.
