  1. Review: Hematology Krystal Pearce, MHS, MT(ASCP), CLS (NCA) Louisiana State University Health Sciences Center School of Allied Health Professions Department of Clinical Laboratory Sciences

  2. Reward Yourself!

  3. Before the test • Study plan • What • When (best time of day) • Where • How

  4. Preparation • Learn material • Exercise • Rest • Cofidence • REWARD!

  5. Practice

  6. Test Day • Dress comfortably • Arrive early • Come prepared

  7. Test Day • Come prepared • Schedule letter • Photo ID (may need two forms, current name and photo!) • Avoid other students • NO last minute review

  8. During the test • Relaxed & confident • Positive self-talk • Comfortable but alert • Maintain an upright posture

  9. Math problems • Write down formula first • Before you calculate, estimate • After you calculate, evaluate (sense) • At end of question, REDO all math

  10. During the test • Answer before looking • Memory lapses normal-don’t panic • Deep breathing

  11. During the test • Budget your time • Make yourself go back over the test question • Check ALL math

  12. Selecting the correct answer • Use qualifiers as clues • no, never, always, every, . . . • Restrictive • sometimes, often, frequently, generally . . . • More likely reflect reality

  13. Selecting the correct answer • NEVER heard of choice? • Probably NOT true

  14. Guessing • Eliminate those you KNOW are wrong • Reread the stem and remaining choices

  15. Computer Adaptive Testing • Correct response Wrong response • Harder item Easier item

  16. Computer Adaptive Testing • “Tailored” test • ability level = fair test • Test security maximized • Variety of items • less pass-along

  17. Computer Adaptive Testing • Random order of content • MUST answer when presented

  18. BOR Skill levels • Recall • Interpretative skills • Problem solving

  19. Check lists • Manageable chunks • Short review sessions • Longer study sessions

  20. RBC Morphology & Inclusions

  21. H I G K L J O M N

  22. P Q R S T U X V W

  23. Helpful Hints • Visualize- names often descriptive • Sickle cells • Auer rods • Cabot ring

  24. What hemoglobin abnormality is suggested by this peripheral blood smear? • A. CC • B. AS • C. SS • D. AC • E. SC

  25. What hemoglobin abnormality is suggested by this peripheral blood smear? • A. CC • B. AS • *C. SS • D. AC • E. SC

  26. RBC Disorders

  27. All of the following are associated with this disorder EXCEPT: • A. Abnormal RBC indicies • B. Abnormal retic count • C. Normal or small spleen • D. Abnormally susceptible to hypoxia

  28. All of the following are associated with this disorder EXCEPT: • A. Abnormal RBC indicies • B. Abnormal retic count (response to hemolysis!) • C. Normal or small spleen • D. Abnormally susceptible to hypoxia

  29. If this cell morphology was observed, the next step would be to perform: • A. Hemoglobin electrophoresis. • B. A bone marrow iron stain. • C. Kleihauer-Betke stain. • D. An erythrocyte sedimentation rate.

  30. If this cell morphology was observed, the next step would be to perform: • *A. Hemoglobin electrophoresis. • B. A bone marrow iron stain. • C. Kleihauer-Betke stain. • D. An erythrocyte sedimentation rate.

  31. What disorder could this morphology indicate? • A. Iron deficiency anemia • B. Folate deficiency • C. Acute leukemia • D. Infectious mononucleosis

  32. What disorder could this morphology indicate? • *A. Iron deficiency anemia • B. Folate deficiency • C. Acute leukemia • D. Infectious mononucleosis

  33. What disorder could this morphology indicate? • A. Iron deficiency anemia • B. Hereditary elliptocytosis • C. DIC • D. Infectious mononucleosis

  34. What disorder could this morphology indicate? • A. Iron deficiency anemia • B. Hereditary elliptocytosis • *C. DIC • D. Infectious mononucleosis

  35. What further lab tests are suggested by this morphology? • A. Serum iron and ferritin • B. Genetics carrier screening • C. Coag panel • D. EBV titers • E. Hgb electrophoresis

  36. What further lab tests are suggested by this morphology? • A. Serum iron and ferritin • B. Genetics carrier screening • *C. Coag panel (PT, PTT, fibr., FDP, D-Dimer) • D. EBV titers • E. Hgb electrophoresis

  37. Schistocytes • Can cause spurious incr. Plt counts

  38. WBC Morphology (& Inclusions)

  39. What is the best description of the WBC? • A. Variant lymphocyte • B. Pyknotic nucleus • C. Hypersegmented • D. Toxic granulation • E. Vacuolation

  40. What is the best description of the WBC? • A. Variant lymphocyte* • B. Pyknotic nucleus • C. Hypersegmented • D. Toxic granulation • E. Vacuolation

  41. What is the best description of the WBC? • A. Variant lymphocyte • B. Pyknotic nucleus • C. Hypersegmented • D. Toxic granulation • E. Vacuolation

  42. What is the best description of the WBC? • A. Variant lymphocyte • B. Pyknotic nucleus • *C. Hypersegmented • D. Toxic granulation • E. Vacuolation

  43. What can be done to help prevent this type of problem on peripheral smears? • A. Add albumin to blood then make smear • B. Use auto. Slide maker • C. Dilute blood with saline • Collect in Na citrate www.wadsworth.org
