What is Agranulocytosis?
A condition where there is a dangerously low number of white blood cells called granulocytes in the blood
What is Erythropoiesis?
The process of producing red blood cells (RBCs) in the body
What is hemolysis?
The process of red blood cell destruction. It occurs when red blood cells (RBCs) break down prematurely, releasing their hemoglobin into the bloodstream. This can be caused by various factors, including:
Inherited disorders: Such as sickle cell anemia and thalassemia.
Infections: Like malaria and sepsis.
What is megaloblastic anemia?
Is a type of anemia characterized by abnormally large, immature red blood cells (megaloblasts).
Megaloblastic anemia is primarily caused by deficiencies in which two essential vitamins?
Vitamin B12 (cobalamin) and Folate
Megaloblastic anemia is also caused by three other reasons, and they are?
Malabsorption disorders (e.g., celiac disease, Crohn’s disease)
Certain medications (e.g., methotrexate, hydroxyurea)
Inherited disorders (e.g., megaloblastic anemia due to inherited disorders of folate metabolism)
Pancytopenia is a medical condition characterized by a significant decrease in the number of all three types of blood cells. Can you name the types of blood cells ? (PAN means all)
- Red blood cells (erythrocytes): Carry oxygen throughout the body. 4.35-5.65
- White blood cells (leukocytes): Fight infections. 5-10,000
- Platelets: Help with blood clotting. 150-450,000
Polycythemia is defined as characterized by an abnormally high number of what type of cell?
RBC -Polycythemia is defined as a hematocrit (percentage of red blood cells in the blood) greater than 52% in men and 48% in women,
What is neutropenia?
A condition characterized by an abnormally low number of neutrophils in the blood- a count less than 1500
Tissue hypoxemia is a condition where there is an inadequate supply of what to the body’s tissues?
1. Blood
2. Oxygen
3. WBCs
4. Water
Oxygen
What is anemia?
A medical condition where the body does not have enough healthy red blood cells
True or False Anemia can be caused by various factors, including blood loss, iron deficiency, vitamin deficiencies (B12 and folate), chronic diseases (e.g., kidney disease), and bone marrow disorders.
True
What foods would a nurse recommend for a person with anemia?
A nurse may recommend iron-rich foods to a client with iron deficiency anemia, such as red meat, seafood, beans, and dark green leafy vegetables.
Microcytic, normocytic, and macrocytic anemia are types of anemia categorized by what in particular?
The size of RBCs
What are the three types of anemia?
Microcytic, normocytic, and macrocytic
What is a condition where the number of platelets in the blood is abnormally low?
Thrombocytopenia-
(normal platelet count is 150-450,000)
What is a protein produced by the parietal cells in the stomach lining? It plays a crucial role in the absorption of vitamin B12 (cobalamin) in the small intestine.
IF -intrinsic factor
What is a condition in which there is an abnormally low number of white blood cells (leukocytes) in the blood?
Leukopenia
What is the normal WBC count?
4-11,00 or 5-10,00
What is a type of anemia where red blood cells (RBCs) are destroyed prematurely, leading to a decrease in the number of healthy RBCs in the bloodstream?
Hemolytic Anemia
Hemolytic anemia can be a result of three conditions can you name them?
1) Inherited disorders: Such as sickle cell anemia, thalassemia, and G6PD deficiency.
2) Acquired conditions: Such as autoimmune diseases, infections, blood transfusions, and certain medications.
3) Mechanical damage: From trauma, surgery, or prosthetic heart valves.
What are some nursing diagnosis for a client with anemia?
Fatigue, decreased activity tolerance, and inadequate oxygenation. Other diagnoses can include nutritional deficiencies, risk for infection, and risk for bleeding.
Adults over the age of 65 are at risk for nutrition deficient anemias (iron, vitamin B 12, and folate True or False?
True
Gastrointestinal bleeding is a common cause of anemia in adults > 65 True or False
True
