Is There a Code Yellow?

The sounds of children's screams still make my skin crawl. The most memorable time during her university training was the code yellow we got on the floor one day. All non-essential nursing staff should immediately help in locking down the exits to ensure that the child can't leave. If I wasn't under the washable eye of my supervisor I think I'd have lost my mind with panic. It took until a supervising nurse told me for me to really understand how horrifying it was.
