  • Hematology Assignment
    Hematology Assignment This unit is big, and mastery of the material requires a combination of reading the book, reviewing lecture notes and especially attention to the online exercises. It covers RBC and WBC disorders, problems of coagulation and diseases of the lymph nodes. Do not wait until week before the exam to try and do the reading. All of the material in this unit will be covered on the second exam, and it’s a bunch. You’ll be sunk if you put reading and online assignments off until the just few weeks before the exam. Here’s the scoop on just the hematology unit, the immunopathology comes later. Big Robbins: chapters 13 and 14. Little Robbins: Chapter 11 Wheater: Hematopoietic Slides: For the blood smears, the entire set is online. There are no slides in your box. For the lymph nodes, there are slides in your box and online. There are four online exercises for hematology unit, two cases and two tutorials. The tutorials are rather large but absolutely necessary. Don’t flush these or try to rush through them. Online stuff: Case 11, Mr. Herbert: A man complaining of lethargy. Module 24, Coagulation tutorial Module 19, Leukemia review Case 17, Mrs. Talbot: Woman with a neck mass. Slides and TBL stuff: There are no formal TBLs for this unt. Rather the blood smear section of the slides will serve that purpose. Approach of these cases as if you will see them, their histories and lab values in case studies on the written exam. The reason is, you will.
