Which of the following statements is common to most lipid storage diseases? | They are caused by a missing metabolic enzyme. |
What is an unusual complication that may occur in infectious mononucleosis? | Hemolytic anemia |
A patient who has a persist leukocytosis, Dohle bodies, and an elevated LAP score most likely has a: | Leukemoid reaction |
What pools of leukocytes are included in the typical white blood count? | only cells freely circulating |
What pools of cells is the first to arrive when extra granulocytes are needed in the tissues? Those: | that are marginating. |

What is the earliest stage of maturation where a neutrophil can be distinguished from an eosinophil? | myelocyte |
What neutrophils are capable of chemotaxis? | band |
A segmented neutrophil performs all of the following: | chemotaxis, phagocytosis, and pinocytosis |
A segmented neutrophil can NOT perform: | mitosis |
What cells are described as a large cell with abundant cytoplasm containing minute granules, lacy chromatin, and an indented or curved nucleus? | Monocyte |
Which cells are normally produced in multiple sites including the bone marrow, and thymus? | Lymphocytes |
B cells and T cells are subgroups of what cell type? | Lymphocytes |
Lymphocytes become transformed when they are: | being stimulated by an antigen. |
An autosomal disorder that manifests itself with large lysosomal inclusions, recurring infections, and albinism: | Chediak-Higashi |
Pelger-Huet anomaly is characterized mainly by: | Hyposegmentation of the nucleus is the neutrophils |
Dohle bodies consist of: | Ribosomal RNA |
All of the following are lipid storage syndromes/diseases: | Gaucher's disease, Tay-Sachs disease, and Niemann-Pick disease |
This is not a lipid storage syndrome/disease: | Chediak-Higashi syndrome |

In what condition are monocytes increased? | Tuberculosis |
What is the causative agent in infectious mononucleosis? | EBV |
The process of ingesting, digesting, and killing bacteria is termed: | Phagocytosis |
Qualitative changes in the white blood cell include all of the following: | Toxic granulation, toxic vacuolization, and dohle bodies |
Qualitative changes in the white blood cell does NOT include: | Gaucher's cells |

DO NOT see: reactive monocytes |
Opsonization of neutrophils is defined as: | preparing neutrophils to be ingested |
All of the following are mechanisms by which neutropenia is usually produced: | decreased production by the bone marrow, impaired release from the bone marrow to the blood, and increased destruction |
The mechanism by which neutropenia is NOT usually produced: | bacterial infection |
