Study Notes
Anemia
- A deficiency in the number of erythrocytes (RBCs) or the quantity of hemoglobin (Hgb) or the volume of packed RBCs (hematocrit)
- Not a specific disease, but rather a manifestation of a pathological process
- Diagnosis based on complete blood count (CBC), reticulocyte count, and peripheral blood smear
Causes of Anemia
- Deficient nutrients (iron, cobalamin, folic acid)
- Decreased erythropoietin
- Decreased iron availability
- Blood loss (chronic or acute)
- Increased RBC destruction (hemolysis)
- Sickle cell disease
- Medication
- Incompatible blood
- Trauma
- RBC function
Functions of RBCs
- Transport oxygen from lungs to systemic tissues
- Carry carbon dioxide from tissues to lungs
Classification of Anemia
- Morphology
- Cellular characteristics
- RBC size and color
- Etiology
- Cause
- Clinical condition causing anemia
Lab Values
- Hemoglobin: Male 14-18 (g/dl), Female 12-16 (g/dl), Low < 6.0, High > 20.0
- Hgb levels are often used to determine severity of anemia
Manifestations of Anemia
- Restlessness and irritation
- Fatigue
- Shortness of breath
- Vary based on how fast anemia has evolved, its severity, and any coexisting disease
- Fatigue/weakness, dyspnea, dizziness, palpitations
- Pallor
- Decreased Hgb
- Decreased blood flow to the skin
- Conjunctiva of the eyes can appear pale
Nursing Interventions
- Alternate rest and activity
- Prioritize activities to accommodate energy levels and to maximize O2 supply for vital functions
- Get ADL's done early
- Aid to minimize risk of injury from falls
- Monitor cardiorespiratory response
- Evaluate nutritional needs
Iron Deficiency Anemia
- Most common nutritional disorder in the world
- Most susceptible: very young people, poor diet, women in reproductive years
- Iron rich foods: grains, red meat, leafy greens, shellfish, egg yolks, cooked spinach, green peas, broccoli, brussels sprouts, poultry, dried fruits, legumes
- Etiology: inadequate dietary intake, malabsorption, blood loss
- Clinical manifestations: dyspnea, fatigue, pallor, palpitations, dizziness, glossitis, cheilitis
- Diagnostic studies: Hgb, Hct, MCV, MCH, MCHC, reticulocytes, ferritin, serum iron, TIBC, bilirubin, platelets
- Interprofessional and nursing management: treat underlying problem causing loss, reduced intake or poor absorption of iron

Description
This quiz covers the definition, causes, and diagnosis of anemia, a deficiency in red blood cells or hemoglobin. It includes the factors that contribute to anemia, such as nutrient deficiencies and decreased erythropoietin, as well as the methods used to diagnose anemia, including complete blood counts and peripheral blood smears.
