[sociallocker]Correct answer is C. This is a patient with acute onset dyspnea and clinical features suggestive of upper respiratory obstruction. Given his history of food allergies and urticarial, laryngeal edema is likely the cause of his respiratory symptoms. Patients with laryngeal edema typically present with acute onset dyspnea. There is usually an identifiable precipitating event, e.g. peanut ingestion in a patient with a history of peanut allergies. Physical examination will reveal stridor and harsh respiratory sounds from the trachea. Wheezing is generally absent on lung auscultation.
