Cancer Flashcards
_____ carry hemoglobin for oxygenation tissues.
Low-anemia
High- polycythemia
Erythrocytes
Low erythrocytes (RBC) is called
Anemia
High erythrocytes level is called
Polycythemia
____ main function is immune system (innate) inflammation
Leukocytes
Low leukocyte level is ___ ___
Immune dysfunction
Cancer leukemia
___ main function is immune (acquired)
Problems is lymphoma cancer and multiple myeloma
Lymphocytes
____ forms blood clots (thrombi) and stops bleeding
Thrombocytes
Low thrombocytes means there is ___
Bleeding
High thrombocytes Meanss there is ____
Clotting DVT
Anemia means
Not enough RBC, RBC doesn’t have enough Hgb to carry oxygen. Check Hgb level and types of Hgb (electrophoresis) and RBC don’t work right (shape/morphology)
Know
Anemia manifestations:
Reduced oxygen carrying capacity
Fatigue, weakness, dyspnea, dizziness w position change
Signs: Rapid HR Pallor Heart murmur Enlarged heart even failure Pale conjuctiva
Know
What triggers RBC production:
Low oxygen levels in the kidneys stimulates release of ERYTHROPOIETIN, a hormone.
Erythropoietin stimulates the bone marrow to release RBC
Sometimes immature RBC reticulocytes are released, indicating higher production
Need enough iron to make the hemoglobin for new RBC
Know
Two causes of anemia
Loss of RBC or diminished erythropoiesis (not making RBC)
Know
If the terms end in ____ it is describing size of a cell
Either size hemoglobin or shape
Cytic
Macrocytic means ___
Large
Microcytic means ____
Small
Normocytic means ____
Normal size
Terms that end with chromic means _____ ___
Size Hgb or shape
Hemoglobin content
Normochromic means normal ___
Hgb
Hypochromic means
Low Hgb
____ is red cells in different sizes
Anisocytosis
____ is red cells in various shapes
Poikilocytosis
____ ___ anemia is acute blood loss. Normocytic normochromic (normal size and Hgb normal) too fast to compensate cells look normal. TRAUMA AND SURGERY causes
Post hemorrhagic
___ ___ anemia is chronic blood loss, blood loss is greater than replacement capacity of bone marrow. Associated with SLOW blood loss like menstruation or colon cancer
Iron deficiency
Blood loss due to RBC destruction as well-
hemolytic anemia:
RBC are destroyed faster than they can be made: ex sickle cell disease, auto immune disorder
Happens fast and can be lethal
Know
Macrocytic normochromic anemia (big RBC)
Also called megablastic anemia
Unusually LARGE STEM CELLS
DEFECTIVE DNA SYNTHESIS
nutrient deficit of folate and vitamin b 12
Know
____ anemia cause is lack of intrinsic factor from gastric parietal cells. Require vitamin b12 absorption. When Hgb drops 7-8 g/dL. Weakness, fatigue, difficulty walking; PARESTHESIAS, loss of appetite, abdominal pain, weight loss, sore tongue
Neurologic manifestations irreversible*
Life long b 12 replacement
Pernicious anemia
___ deficiency (macrocytic anemia) DAILY dietary intake of folate. 50-200mg qd, absorption of folate occur in upper small intestine and no Neuro symptoms, common in alcohol abuse
Folate deficiency
Iron deficiency anemia is the most common type of anemia world wide.
Microcytic hypochromic anemia’s- small pale RBC
Red cells are small and low Hgb *
Related to iron deficiency *
Chronic loss of RBC
Poor intake or absorption
Know
Microcytic hypochromic anemia: iron deficiency
You’ll see manifestations when Hgb decreases to 7-8 per/dL
Early symptoms: fatigue, weakness, shortness of breath, pale earlobes, Palms and conjuctiva
Progress of iron deficiency anemia causes brittle thin coarsely ridgid and spoon shaped nails (kolionychia) cheilosis, stomatitis, painful ulceration in mouth and dysphasia
Know
Normocytic, normochromic anemia’s
Cells are NORMAL but not enough of them *
Cause:
Acute blood loss, or hemorrhage
Hemolysis/ red blood cells broken down, die too soon.
Chronic illness or inflammation
A plastic anemia- bone marrow can’t make ANY blood cell types
Know
___ is where RBC broken down, die too soon.
Hemolysis
___ anemia is where bone marrow can’t make ANY blood cell Tyler
Aplastic anemia
___ anemia is a rare anemia. *reduction in RBC, WBC, and platelets.
Manifestations: all types of blood cells missing.
Low RBC- fatigue and pallor
Low platelet: petechiae, bruising, bleeding gums, GI
Low wbc increased infections
Why? Damaged bone marrow due to cancer leukemia, radiation, meds or chemo
Aplastic anemia
___ anemia normocytic normochromic anemia, RBC FRAGILE*, causes drugs infection, difficult to get rid of Hgb breakdown so they get jaundice**
Hemolytic
Anemia of chronic disease is due to decreased erythropoiesis and impaired iron utilization in chronic disease or inflammation
