    Study Notes

    Hematopoiesis

    • Bone marrow is responsible for blood cell production
    • Produces stem cells that mature into various blood cell types: red blood cells, white blood cells, and platelets

    Red Blood Cells

    • Erythrocytes transport oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs
    • Contain hemoglobin, a protein that binds oxygen

    White Blood Cells

    • Leukocytes are responsible for immune responses
    • Include granulocytes (neutrophils, eosinophils, basophils) and lymphocytes
    • Granulocytes participate in host defenses against bacteria, fungi, and foreign substances
    • Lymphocytes are involved in adaptive immunity

    Platelets

    Hematological Function

    • Blood is formed and matured in the bone marrow.
    • Bone marrow constitutes 4-5% of total body weight.
    • Red blood cells (erythrocytes) are the most abundant blood cell type.
    • Hemoglobin is present in red blood cells. Each red blood cell contains thousands of hemoglobin molecules.
    • Hemoglobin picks up oxygen from the lungs and delivers it to tissues.
    • Hemoglobin picks up carbon dioxide from tissues and delivers it to the lungs.
    • White blood cells (leukocytes) are the least abundant blood cell type.
    • There are 4,500 - 11,000 white blood cells per mm3.
    • White blood cells represent 1% of blood volume.
    • White blood cells can migrate to other tissues.
    • White blood cells play a role in immune response against microorganisms, destruction of cancer cells, and wound healing.
    • Neutrophils are a type of granulocyte.
    • Neutrophils participate in host defenses against bacteria, fungi, debris, and foreign substances.
    • Neutrophils are phagocytic cells.
    • Eosinophils are another type of granulocyte.
    • Eosinophils comprise 1-3% of total white blood cells.
    • Eosinophils destroy foreign cells.
    • Eosinophils play a role in hypersensitivity reactions.
    • Basophils are another type of granulocyte.
    • Basophils are involved in responses against antigens, pathogens, and parasites.
    • Platelets (thrombocytes) control bleeding.
    • Platelets are stored in the spleen.
    • Plasma comprises a complex mixture of water, proteins, nutrients, electrolytes, nitrogenous wastes, hormones, and gases.
    • The spleen filters blood.
    • The spleen removes abnormal white blood cells and platelets.
    • The spleen plays a role in host defense.
    • The spleen stores blood and platelets.
    • The spleen is involved in lymphocyte formation.
    • Hemoglobin transports oxygen throughout the body.
    • The clotting cascade is a process that includes intrinsic and extrinsic pathways.
    • The clotting cascade is triggered by the formation of a platelet plug.
    • Hemostasis is a process that prevents blood loss from a damaged blood vessel and encompasses the following steps:
      • Vasospasm.
      • Formation of a platelet plug.
      • Development of a fibrin clot.
      • Clot retraction.
      • Fibrinolysis.
    • Blood clotting is initiated by a series of reactions called the clotting cascade, designed to control bleeding.
    • Inflammation and immunity are processes involved in eliminating the cause of injury, removing damaged tissue, and generating new tissue.

    Hematological Assessment

    • A nutritional history should be obtained.
    • Patients should be asked about recent changes in energy levels, ability to perform daily activities, pain, burning, or tingling sensations, changes in skin color or temperature, swelling (edema), bleeding or bruising tendencies, dizziness, fatigue, or changes in lymph nodes.
    • A past medical history should be obtained.
    • Patients should be asked about chronic diseases, pregnancies, hepatitis, cirrhosis, cancer, gallstones, or conditions that could affect vitamin K absorption ability.
    • A medication history should be obtained.
    • Patients should provide a list of all medications, including anticoagulants, aspirin, salicylates, herbs, nutritional supplements, and nutraceuticals.
    • Skin, head, and neck should be assessed during a physical examination.
    • Color of skin and mucous membranes should be evaluated.
    • Skin temperature, capillary refill, and edema should be assessed.
    • Skin and lymph nodes should be palpated.
    • Oral mucous membranes and skin should be inspected.
    • The tongue should be inspected.
    • Respiratory rate, rhythm, depth, and sound should be assessed during a respiratory physical examination.
    • Respiratory rates of less than 12 or greater than 20 breaths per minute are considered abnormal.
    • Vital signs and auscultation should be assessed during a cardiovascular physical examination.
    • The urinary meatus should be inspected for bleeding.
    • A urine specimen should be collected for analysis.
    • Abdominal pain and bone pain should be assessed during a musculoskeletal physical examination.
    • Range of motion of affected joints should be assessed.
    • The abdomen should be inspected and palpated.
    • If splenomegaly is noted, it should be palpated gently, as deep palpation could cause the spleen to rupture.

    Diagnostic Studies

    • A complete blood count (CBC) should be ordered.
    • A complete blood count measures hemoglobin, hematocrit, red blood cells, white blood cells, and platelets.
    • A reticulocyte count should be ordered.
    • An increase in reticulocyte count may suggest a response to treatment for anemia.
    • A decrease in reticulocyte count may indicate a problem with red blood cell production.
    • Hemoglobin electrophoresis separates and measures normal and abnormal hemoglobin.
    • Leukocyte alkaline phosphatase is an enzyme produced by normal mature neutrophils.
    • The Coombs test is used to detect the presence of immunoglobulins on red blood cells.
    • Iron studies.
    • Iron studies include serum ferritin, transferrin, and total iron-binding capacity.
    • Clotting studies.
    • Clotting studies include prothrombin time, bleeding time, international normalized ratio, partial thromboplastin time, and platelet aggregation.
    • Exams of bone marrow.
    • Bone marrow exams include bone marrow aspiration and bone marrow biopsy.

    Case Study

    • Ms. Starr is a 25-year-old female patient presenting with generalized fatigue and increased shortness of breath.
    • Ms. Starr's physical examination reveals a heart rate of 118 beats per minute, a blood pressure of 90/72 mm Hg, and a respiratory rate of 26 breaths per minute.
    • Ms. Starr's skin and nailbeds are pale, and her tongue is red and swollen.
    • Ms. Starr's complete blood cell count (CBC) with differential reveals the following:
      • RBC count of 3 million/mm3.
      • Hct of 31%.
      • Hgb of 9 g/dL.
    • Ms. Starr's serum ferritin levels are decreased.
    • The decrease in RBC count, Hct, Hgb, and ferritin levels, combined with the patient's complaints and physical examination findings, indicate iron-deficiency anemia.
    • Ms. Starr is prescribed iron supplements and referred to a hematologist for further evaluation.
