Session 8 GI Questions - University of Nevada School of MedicineSess


    Gastroenterology Remediation Questions


    Remediation this year will be done twice a month at a noon seminar time. It is MANDATORY for you to attend ALL of these

    sessions. The only exceptions are if you are on vacation, night shift, or actively participating in an ER shift. You are required to attend if you are in the ER for the month but not working on the day of remediation.

    This year’s program will consist of board style review questions to be discussed by the group. Approximately 1 week prior to the session you will each be assigned to a question. Your job is to research the answer and present teaching points related to the

    question assigned to the group. Please send us a written explanation of the question 2 days before the remediation session so we can provide everyone with the answers and explanations after the session. We encourage you guys to bring pictures, mnemonics,

    etc. to help teach your question. Attending physicians and the chief residents will be present to facilitate added discussion, however the responsibility of education is on you as a group. We expect each of you to arrive prepared and willing to contribute.
