  1. list and interpret critical clinical findings, including
    1. history of drug ingestion, food ingestion, stings, environmental and occupational exposures, exercise, or family history;
    2. results of an appropriate physical examination;
  2. list and interpret critical investigations, including
    1. appropriate use of tests designed to identify allergens;
