How fast should the patient be seen at the er having allergies

I don’t really know how the triaging works on private hospitals if a pedia patient came in with allergies face and body all covered in urticaria rashes eyes swelling but patient is still alert and conscious with no dob. Vitals are unremarkable except for the pulse patient also complains of throat itchiness. This seems to be an emergency but somehow the triage nurses doesn’t seem to have any sense of urgency. I understand that it might be the clinical clerk’s first rotation and is still learning but weren’t they oriented with proper referral and endorsements? Pedia patient was seen over an hour after the mom asked to be triaged out and to just transfer to another facility since no doctor came to check the Pedia patient. After over an hour ROD came and checked and only gave oral antihistamines it eventually worked for a while and patient was sent home but after several hours he had another allergic reaction patient was seen by a pediatric consultant mother told her about the recent visit to the ER and Pedia consultant wondered why the patient wasn’t given a shot? Good thing the patient is okay and is recovering. Question: what should’ve have been the process when a pedia patient came in with allergies? Do you think the clinical clerk failed to inform the ROD about the patient or at least just gave a short or brief description of the patient because she was scared that if she refers the patient without a complete history she would be given an extension? Or let’s say clinical clerk referred with a brief description but ROD was fast asleep and couldnt hear her phone ringing? Do er nurses or triage nurses not refer the patients coming in the er anymore since there are interns in the hospital already? How long should the patient be on hold if suffering from allergies? And what is the guidelines on managing patients with allergies? A Pedia patient.
