Correct answer: B — Remove latex exposure, arrange IgE-focused allergy assessment and document an emergency plan
Explanation lettering: D = shown as B · E = shown as D · B = shown as E
D is correct. Immediate contact urticaria, angioedema and respiratory symptoms after latex exposure indicate a potentially systemic type I, IgE-mediated reaction. Exposure should stop, occupational health and allergy assessment should be arranged, and the worker needs documented avoidance and emergency planning appropriate to severity. Patch testing investigates type IV allergy to rubber additives and does not assess immediate latex-protein allergy. Cotton liners do not prevent airborne or direct allergen exposure, emollients address irritant dermatitis rather than wheeze, and deliberate workplace challenge is unsafe. Employers should provide a suitable latex-free environment while protecting confidentiality and reviewing fitness for duties.
