This is a Type IV delayed hypersensitivity reaction, which is mediated by T cells and manifests days after exposure to the antigen. In this case, the client's exposure to something in the garden led to the development of an erythematous rash on the hands after 2 days, fitting the timeline for a Type IV reaction.
