EXAM 7 Hematology Oncolgy
Glucose is important to the body because?
The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells Glucose is transported from the intestines or liver to body cells via the bloodstream, and is made available for cell absorption via the hormone insulin, produced by the body primarily in the pancreas.
What is the white layer that is between the RBC's and the Plasma layer? What does it contain?
The buffy coat, WBC's, platelets, +/- microfilariae, +/- NRBC's. Nucleated RBCs (NRBCs) are immature RBCs are not normally seen in the peripheral blood beyond the neonatal period.
"A nurse is caring for a 25-year-old client with end-stage testicular cancer who has been referred to hospice care. Which of the following criteria excludes the client from hospice care?

Therefore, the nurse should identify the client's tobacco use as being the greatest risk factor for developing bladder cancer.
The nurse is preparing a client for magnetic resonance imaging (MRI) to confirm or rule out a spinal cord lesion. During the MRI scan, which of the following would pose a threat to the client?
The client wears a watch and wedding band
FALSE
The correct term for an increase in neutrophils is neutrocytosis
Cytoplasm is
The fluid portion of a cell, excluding the nucleus
Plasma is....
The fluid portion of anti-coagulated whole blood - would come from a LTT, Gray TT, or Green TT. Plasma has two acceptable "normal" color options: Clear or Straw.
Serum is....
The fluid portion of coagulated blood - would come from RTT, Serum Seperator Tube (Marble Top Tube),
Chromatin is
The genetic material of the cell nucleus
MCHC (Mean Corpuscular Hemoglobin Concentration) is..... Formula for MCHC calculation is: Hb (hemoglobin) X 100 / (divided by) PCV (packed cell volume) This is rounded to tenths place and reported in g/dl Do cells have the correct amount of Hb (hemoglobin) in them for that species?
The mean corpuscular hemoglobin concentration, a measure of the concentration of hemoglobin in a given volume of packed red blood cells. It is reported as part of a standard complete blood count. Reported as NR = Normochromic Higher than normal = Hyperchromic Lower than normal = Hypochromic (cells are lacking in hemoglobin (Hb)
MCV (Mean Cell Volume) is... Formula for MCV=PCV(packed cell volume) X 10 /(divided by) RBC's = (fl) fentoliters is unit - round to tenths place Microcytic cells are smaller than they should be for a species Macrocytic cells are larger than they should be for a species
The mean corpuscular volume, or "mean cell volume" (MCV), is a measure of the average red blood cell size that is reported as part of a standard complete blood count. The MCV is calculated by dividing the total volume of packed red blood cells (also known as hematocrit) by the total number of red blood cells. The resulting number is then multiplied by 10. The red blood cells get packed together when they are spun around at high speeds in a centrifuge. In patients with anemia, it is the MCV measurement that allows classification as either a microcytic anemia (MCV below normal range), normocytic anemia (MCV within normal range) or macrocytic anemia (MCV above normal range).
FALSE
The order of the granulocyte pools is: Dividing, Maturation, Storage, Marginating, Circulating & the tissues

The reticulocyte count is used to help determine if the bone marrow is responding adequately to the body's need for red blood cells (RBCs) and to help determine the cause of and classify different types of anemia. The number of reticulocytes must be compared to the number of RBCs to calculate a percentage of reticulocytes; so the test is ordered along with a RBC count. A hemoglobin and/or hematocrit are usually ordered in order to evaluate the severity of anemia.
Thrombocytes are...
The smallest formed elements in the blood. There purpose is blood clotting and they are formed in the red bone marrow.

The nurse should expect a client who has iron-deficiency anemia to have weakness, pallor, fatigue, reduced tolerance for activity, and cheilosis (ulcerations of the corners of the mouth). The nurse should expect a client who has folic acid deficiency to have pallor and jaundice; a smooth, beefy-red tongue (glossitis); fatigue; and weight loss. This type of anemia is caused by nutritional deficiencies, malabsorption syndromes (Crohn's disease), and medications (e.g., anticonvulsants, oral contraceptives). A client who has pernicious anemia is unable to absorb vitamin B12 due to a lack of intrinsic factors in the stomach. The nurse should expect this client to have pallor and jaundice; a smooth, beefy-red tongue (glossitis); fatigue; weight loss; and paresthesias to the hands and feet. Sickle cell anemia is an autosomal recessive disorder in which the RBCs develop a sickle shape following conditions in which decreased oxygen is available. These sickled cells then clump together and become fragile, causing tissue ischemia leading to eventual organ damage. Manifestations of sickle cel anemia include pain, pallor, cyanosis, dyspnea, fatigue, and weakness.

Which of the following transfusion reactions should the nurse suspect? a. Febrile b. Allergic c. Acute Pain d. Hemolytic
D A hemolytic transfusion reaction occurs when antibodies in the recipient's blood react to foreign blood cells introduced by the transfusion. The antibodies bind to the foreign cells and destroy them in a process known as hemolysis. The destroyed cells are excreted by the kidneys (hemoglobinuria), causing the red-tinged urine. Hemolytic transfusion reactions can result in acute renal injury, disseminated intravascular coagulation, and circulatory collapse. -- A febrile transfusion reaction can occur in clients who have received multiple blood product transfusions. It is a response in which anti-white blood cell (WBC) antibodies react with the WBCs remaining in the blood product. This results in chills, fever, hypotension, tachycardia and tachypnea. Clients who have a history of multiple blood product transfusions may receive leukocyte reduced blood or single-donor HLA matched platelets along with a WBC filter to prevent febrile reactions. Allergic (anaphylactic) transfusion reactions occur most often in clients who have pre-existing allergies. It is thought to be the result of a reaction to the plasma protein contained in the blood product. Manifestations include urticaria, itching, and flushing. In extreme cases, bronchospasm and laryngeal edema, and shock may occur. Onset may occur as late as 24 hr following the transfusion. Clients who have a history of allergies may receive blood products in which the WBCs, plasma, and immunoglobulin A has been removed or the client may be pre-treated with antihistamines and corticosteroids. An acute pain transfusion reaction can occur during or following transfusion with blood products. It manifests as severe chest, joint, and back pain, along with hypertension and flushing of the face and neck. The client is often anxious. Acute pain transfusion reactions are treated symptomatically with medications for pain and rigors.

A nurse is assessing a client who has atrial fibrillation. Which of the following pulse characteristics should the nurse expect? a. Slow b. Not palpable c. Irregular d. Bounding
c. Irregular With atrial fibrillation, multiple ectopic foci stimulate the atria to contract. The AV node is unable to transmit all of these impulses to the ventricles, resulting in a pattern of highly irregular ventricular contractions and thus an irregular pulse. Atrial fibrillation is an abnormal cardiac rhythm in which the atria are unable to effectively contract because of multiple rapid stimuli causing the atria to depolarize in an organized manner. The atrial rate can range from 300 to 600 bpm, with the ventricular rate being 120 to 200 bpm. The heart's contraction is not normal in the client who has atrial fibrillation. The atria quiver rather than contract, and the ventricles contract in a rapid, chaotic fashion. The ventricular response provides the client with a palpable pulse, although it may be difficult to count the rate. With atrial fibrillation, the amplitude of the client's pulse is highly variable. There is a decrease in ventricular filling, resulting in varying stroke volumes.

A nurse is caring for a client who is recievig a unit of packed red blood cells. Fifteen minutes following the start of the transfusion, the nurse notes that the client is febrile, with chills and red-tinged urine. Which of the following transfusion reactions should the nurse suspect? a. Febrile b. Allergic c. Acute Pain d. Hemolytic
d. Hemolytic A hemolytic transfusion reaction occurs when antibodies in the recipient's blood react to foreign blood cells introduced by the transfusion. The antibodies bind to the foreign cells and destroy them in a process known as hemolysis. The destroyed cells are excreted by the kidneys (hemoglobinuria), causing the red-tinged urine. Hemolytic transfusion reactions can result in acute renal injury, disseminated intravascular coagulation, and circulatory collapse. A febrile transfusion reaction can occur in clients who have received multiple blood product transfusions. It is a response in which anti-white blood cell (WBC) antibodies react with the WBCs remaining in the blood product. This results in chills, fever, hypotension, tachycardia and tachypnea. Clients who have a history of multiple blood product transfusions may receive leukocyte reduced blood or single-donor HLA matched platelets along with a WBC filter to prevent febrile reactions. Allergic (anaphylactic) transfusion reactions occur most often in clients who have pre-existing allergies. It is thought to be the result of a reaction to the plasma protein contained in the blood product. Manifestations include urticaria, itching, and flushing. In extreme cases, bronchospasm and laryngeal edema, and shock may occur. Onset may occur as late as 24 hr following the transfusion. Clients who have a history of allergies may receive blood products in which the WBCs, plasma, and immunoglobulin A has been removed or the client may be pre-treated with antihistamines and corticosteroids. An acute pain transfusion reaction can occur during or following transfusion with blood products. It manifests as severe chest, joint, and back pain, along with hypertension and flushing of the face and neck. The client is often anxious. Acute pain transfusion reactions are treated symptomatically with medications for pain and rigors.

Erythropoiesis is...
the process by which red blood cells (erythrocytes) are produced. It is stimulated by decreased O2 in circulation, which is detected by the kidneys, which then secrete the hormone erythropoietin.[2] This hormone stimulates proliferation and differentiation of red cell precursors, which activates increased erythropoiesis in the hemopoietic tissues, ultimately producing red blood cells.
Sodium levels in animals is important for:
the regulation of blood pressure, blood volume, the transmission of nerve impulses (signals), as well as the maintenance of acid/base balance in the body. The total amount of sodium affects the amount of fluid in blood and around cells. The body continually monitors blood volume and sodium (and other electrolyte) concentrations. When either becomes too high, sensors in the heart, blood vessels, and kidneys detect the increases and stimulate the kidneys to increase sodium excretion, thus returning blood volume to normal. When blood volume or sodium concentration becomes too low, those sensors trigger mechanisms to increase blood volume. These mechanisms include the following: The kidneys stimulate the adrenal glands to secrete the hormone aldosterone. Aldosterone causes the kidneys to retain sodium and to excrete potassium. When sodium is retained, less urine is produced, eventually causing blood volume to increase. The pituitary gland secretes antidiuretic hormone. Antidiuretic hormone causes the kidneys to conserve fluid. Then blood volume increases.
PCV (Packed Cell Volume) is
the volume percentage (%) of RBC's contained in a whole blood sample. It is the ratio of the volume occupied by packed red blood cells to the volume of the whole blood. Centrifuge is used to spin (force) the RBC's to pack together (PCV) and forces the plasma cells out and to the top of the tube. This reading is made on a microhematocrit card reader.
