D-dimer testing
Chemotherapy with ____ is used for patients with CML in blast crisis with more than __ blasts and is not intended for the chronic phase
idarubicin and cytarabine; 20%
What is imatinib/dasatinib/nilotinib?
tyrosine kinase inhibitor; targets CML with BCR-ABL fusion gene
Approximately 90% of patients with CML present in the chronic phase with less than 10% blasts in the blood and bone marrow.
Pt presents with pancytopenia with significant intravascular hemolysis and hemoglobinuria. Nonspecific abdominal pain and fatigue.
Paroxysmal nocturnal hemoglobinuria
Caused by a mutation in the gene that regulates production of glycophosphatidylinositol-anchoring proteins.
Diagnosis of paroxysmal nocturnal hemoglobinuria is based on ____ which can detect CD55 and CD59 deficiency on the surface of peripheral erythrocytes or leukocytes.
flow cytometry
Patients with coagulopathy of liver disease and low fibrinogen levels who are experiencing bleeding should receive immediate ____ transfusion.
cryoprecipitate
Fibrinogen levels less than ____ associated with active bleeding should be corrected.
100
It is often difficult to distinguish between disseminated intravascular coagulation (DIC) and the coagulopathy of liver disease, but ___ level points to liver disease instead of DIC.
a normal or increased factor VIII
chronic microcytic anemia with hemoglobin levels of approximately 10 g/dL (100 g/L) and a normal hemoglobin electrophoresis pattern
alpha thal trait
chronic microcytic anemia with elevated Hgb A2 and Hgb F
B thal minor
Patients with asymptomatic INR elevation between ___ and ___ are managed by simply withholding warfarin.

How is pre-eclampsia defined?
hypertension, edema, and proteinuria after the 20th week of gestation.
pre-eclampsia vs HELLP vs thrombotic thrombocytopenic purpura-HUS
Pre-eclampsia: SBP >140/DBP>90 after 20th week with edema and proteinuria, can have DIC parameters
HELLP: RUQ pain elevated LFTs, DIC parameters
TTP-HUS: MAHA and low plt in 1st or 2nd trimester with neuro findings and fever; no DIC
A history of mucosal or endometrial bleeding, normal prothrombin and activated partial thromboplastin times, and normal platelet count with evidence of a qualitative platelet defect suggest ____.
von Willebrand disease
