Alterations in Hematologic Function

A set of flashcards covering key concepts and terms related to hematologic function and alterations.

Hemoglobin

A protein in red blood cells responsible for transporting oxygen to the body's tissues.

Erythrocytes

Another name for red blood cells (RBCs), which are responsible for oxygen transport.

Granulocytes

A type of white blood cell (WBC) crucial for the immune response.

Thrombus

A blood clot that forms in a blood vessel and obstructs blood flow.

Thromboembolism

A condition where a blood clot travels and blocks blood vessels.

Deep Vein Thrombosis (DVT)

A blood clot that forms in a deep vein, often in the legs.

Pulmonary Embolism (PE)

A blockage in a pulmonary artery in the lungs, typically caused by blood clots.

Anticoagulants

Medications that prevent blood clotting.

Hemorrhage

Excessive bleeding due to damaged blood vessels.

Anemia

A condition where there is a deficiency in the number or quality of red blood cells.

Vitamin B12 Deficiency Anemia

Anemia resulting from insufficient vitamin B12, leading to fewer healthy red blood cells.

Sickle Cell Anemia

A genetic disorder where red blood cells assume a sickle shape, leading to various health issues.

Multiple Myeloma

A cancer of plasma cells in the bone marrow, characterized by the proliferation of abnormal plasma cells.

Lymphoma

A type of cancer that originates in lymphatic cells, categorized as Hodgkin or Non-Hodgkin lymphoma.

Transfusion Reaction

An adverse response when the recipient's immune system attacks transfused blood cells.

Iron Deficiency Anemia

Anemia caused by inadequate iron, impairing hemoglobin production.

Clinical Presentation of DVT

Symptoms often include pain, swelling, redness, and warmth in the affected limb.

CBC (Complete Blood Count)

A blood test used to evaluate overall health and detect various disorders, including anemia.

Coagulation Studies

Tests measuring how well and how fast blood clots, including Prothrombin Time (PT) and Partial Thromboplastin Time (PTT).

Hydroxyurea

A medication used to treat sickle cell disease by increasing fetal hemoglobin production.

Thrombectomy

A surgical procedure to remove a blood clot.

D-dimer test

A blood test that measures the presence of a substance that's released when a blood clot breaks up.

Pulmonary Embolism Symptoms

Chest pain, shortness of breath, and hemoptysis.

Chest x-ray

An imaging test to check for issues in the lungs and heart.

Chronic Pain in Sickle Cell Disease

Frequent episodes of pain due to sickle cell crises, impacting daily activities and quality of life.
