Good day,my sister was directly sent from the GP an hour ago to the clinic.Complains of chestpain,weakness and vomiting.While she was there,the Sr triaged her as a Green patient.I called my husband and asked to speak to the Sr.She had a attitude,why must she speak to me.When she spoke to me,she was also aggitated.Said they have 2Pshyciatric pts to see.As im also in the nursing profession,i asked her,according to my knowledge,chestpain is a emergency,like the GP said.And as a trauma nurse,i know chestpain is treated as a Orange patient.It is really sad that people react like that as a professional.
