A. Root Cause Analysis A root cause analysis (RCA) is a “systematic approach to understanding the causes of an adverse event and identifying system flaws that can be corrected to prevent the error from happening again” (Huber & Ogrinc, 2010). The root cause analysis is used to determine why the problem occurred in the first place and to identify the cause of a problem using a specific set of steps (Mind Tools, n.d.). The RCA team which consists of interprofessionals who are knowledgeable of the issues and processes related to the incident and the people who are involved in the incident should be formed first before the RCA meeting takes place (Huber & Ogrinc, 2010). In the given scenario, the team includes the emergency department (ED) physician (Dr.T), the RN (Nurse J), the LPN (Mr.B’s LPN), the risk manager, the ER nurse manager, the ER nurse educator, and the quality improvement professional. These members would meet and would discuss the causative factors, errors and hazards that caused Mr.B’s sentinel event. The root cause analysis process has five steps. The first step in conducting a RCA is defining the problem (Mind Tools, n.d.). In the given scenario, the problem is the unexpected death of Mr.B. The second step is collecting the data (Mind Tools, n.d.). It is very important to record and report the data as accurately and as completely as possible. Mr. B’s vital signs, pain scores, laboratory values, and history of medication administered during the situation must be collected. Mr. B is a 67 year old patient who was admitted at 3:30 p.m. for severe left leg and hip pain after a fall. His initial vital signs were blood pressure (BP) 120/80, heart rate (HR) 88, temperature 98.6, and respiratory rate (RR) 32. He rated his pain 10 out of 10 and appeared to be in moderate distress. Mr.B’s left leg was swollen, ecchymotic with limited range of motion. His
