Abstract: This thesis explores the nature of the emergency department environment as it continues to challenge emergency nurses to meet the health needs of an increasingly complex emergency department population. The emergency nurse is also facing conflict and challenge with regard to workplace safety and patient rights. The author suggests that, until recently, very little debate or consideration has been given to the moral dilemmas raised in the ability of emergency department staff to deliver timely and appropriate care in an overcrowded environment. She goes on to say that, in New Zealand, there is no national consistency with regard to the waiting crisis, no national guidelines and no national consensus putting the emergency nurse at risk. This thesis argues the need to acknowledge waiting times as a significant safety issue at a national level as increasing waiting times continue to impact on patient outcomes and nursing practice. It challenges current practice, in particular the role of the emergency nurse and the potential to legitimise expansion of the role to improve the patient experience of waiting in the emergency department.
