What cells are derived from pluripotent hematopoietic stem cells? (think- what are the components of a CBC with differential?)
A 17-year old girl notices a swollen lymph node in her neck and biopsy shows Reed-Sternberg cells. What disease is this?
A 7 year old girl has an elevated white blood cell count, easy bruising and fatigue. What should she be evaluated for?
A newborn baby shows signs of anemia and jaundice within the first 24 hours of life. What might he have?
A woman starts to feel exhausted and light-headed a week after beginning a course of penicillin. What is this?
A patient develops an itchy, raised, red rash 2 to 3 days after using a new brand of detergent. What is this?
A patient begins receiving a blood transfusion. He develops fever, chills, hypotension and DIC. What happened?
A child receives a bone marrow transplant from his healthy brother. Several months later he develops a rash, jaundice and diarrhea. What is this reaction?
An alcoholic man presents with anemia. Would you expect his mean corpuscular volume (MCV) to be high or low? What is he probably deficient in?
A 53-year old man has been feeling tired lately. His hemoglobin level is 8.0. What should you be sure to order?
An elderly woman has lung cancer. What might characterize her anemia for chronic disease?
What infection are blood-transfusion recipients at greatest risk for?
What causes TRALI (transfusion related acute lung injury?)
What characterizes TRALI clinically?
What is the most common metabolic side effect of massive blood transfusion?
What correlates to the severity of a febrile non-hemolytic transfusion reaction?
What is the risk of FFP transfusion?
What causes these allergic reactions?
What type of patients will have anaphylactic reactions?
A 1-year old child is brought to the pediatrician by her mother with complaints of several episodes of turning blue during playing. The child squats down when she turns blue and then a few seconds later she resumes playing. What congenital heart disease can cause this symptom?
What is hemoglobin H disease?
What is hemoglobin Barts?
What are schistocytes and how do they form?
What are the two categories of autoimmune hemolytic anemias?
Mechanistically, what are two ways that hemolysis occurs?
Define erythrocytosis
What coagulation factor is deficient in hemophilia A?
Which coagulation factor is deficient in hemophilia B?
What lab findings characterize DIC?
In ABO blood groups, what is Landsteiner rule?
What blood type is the universal recipient?
What does Rh+ indicate?
What is Rh immune globulin?
What does the direct antiglobulin test (DAT or direct Coombs) detect?
What does the indirect antiglobulin test (IAT or indirect Coombs) detect?
Describe the process for performing both the DAT and IAT
In addition to the Rh system, what are some other clinically significant RBC antigens?
What tests are performed on donated blood to screen for human immunodeficiency virus (HIV) contamination?
What is used as an anticoagulant in blood components?
How does the anticoagulant work?
What are the available blood components for transfusion?
How many units of whole blood does the average adult have in his/her body?
On average, giving 1 unit of packed RBCs should raise the hemoglobin level by how much?
What type of RBCs should be given to patients who have had previous problems with febrile reactions to blood products, or who will be chronically transfused?
What should be used as an intravascular volume expander?
When might you give a patient platelets?
What is the usual dose of platelets?
What are apheresis platelets?
What does cryoprecipitate contain?
What is the most common metabolic side effect of massive blood transfusion?
What correlates to the severity of a febrile nonhemolytic transfusion reaction?
What is the risk of FFP transfusion?
What causes these allergic reactions?
What type of patients will have anaphylactic reactions?
What can be done to prevent anaphylactic reactions in these individuals?
What causes TRALI (transfusion-related acute lung injury)?
What characterizes TRALI clinically?
A patient reports severe nausea and dizziness within an hour of eating shrimp. What type of hypersensitivity reaction is this?
A 4 year old child has allergic rhinitis, eczema (atopic dermatitis) and asthma. What is the hypersensitivity type?
A woman is Rh- and pregnant with her second Rh+ child. If she does not receive anti-Rh immunoglobulin during either pregnancy, what will likely happen?
A newborn baby shows signs of anemia and jaundice within the first 24 hours of life. What might he have?
A woman starts to feel exhausted and light headed a week after beginning a course of penicillin. What is this?
A patient develops an itchy, raised, red rash 2 to 3 days after using a new brand of laundry detergent. What is this?
A patient begins receiving a blood transfusion. He develops fever, chills, hypotension, and DIC. What happened?
What is an autograft?
What is an allograft?
