So, my cousin is an RN in the ER and she was on the panel to interview new grads at her hopsital. She told me to study major cases like Abdominal Aortic Anuerysms, Stroke, MI, Abdominal pain, DKA, Trauma, spinal cord injury. I googled everything I thought was major, life threatening and read up on nursing care for each. On my latest interview they did not ask one single situation question like this! They asked things like "Tell me about yourself," "What do you know about our hospital," "Tell me about a time a patient was upset and yelled at you," "Tell me about a tough decision you had to make." What I did to prepare was google "behavioral style interview questions for nurses." This helped tremendously. You really do need to have real-life examples of situations. That is what they are going to ask you for. I went on several interviews while in nursing school prior to practicing this style and THEY ALL asked this style of question. Best of luck to you!
