The assignment explores the importance of nurses in emergency preparedness, particularly in response to earthquakes and tsunamis. It outlines the three phases of emergency planning: first phase (facilitating care and communication), second phase (emergency operations, search and rescue, public warning systems), and third phase (recovery, psychosocial support, mental health counseling). The paper highlights the need for nurses to be flexible in adjusting their nursing role during disasters, provide leadership in coordinating patient safety, and undertake various roles such as communicator, psychosocial supporter, clinician, leader, and coordinator with joint commission, local governments, and healthcare team.
