This is a case study that I already started. I sent you the guide, an example and my own one with a list of diferential diagnosis. The case study is basically to chose a patient with a symptom, in my case is dysnea, and do a full history taken and assessment, once you do that you give the list of diferential diagnosis. I have started that part, you can read and see that I have done the history taken and cardio and resp assessment and examination for my patient, ( neuro, abdominal and MSK examination was all clear ) I have also done the list with the diferential diagnosis. I need help in the next step You will have to choose a list of 20 of the diferential diagnosis that are more relevant ( some resp, some cardio, some abdominal , cancer must appear) and give a small definition of the diagnosis with a reference using NIce guidelines, CKS …. ( harvard reference ) and then you have to explain why you keep that differential diagnosis or why you refute ( based on the history taken and examination ) giving reason based on evidences and also with references. After that you have to say which test and further procedure you will do to back up your decision, also explaining why and with references. for example my patient would need a chest xray to rule out consolidation.
