Study Notes
NCLEX Review: Iron Deficiency Anemia
- Iron deficiency anemia is caused by low iron levels, leading to decreased red blood cells and hemoglobin, resulting in oxygen deprivation to tissues and organs.
- It is the most common type of anemia, caused by low iron levels leading to fewer red blood cells and less hemoglobin, resulting in decreased oxygen supply to the body.
- Signs and symptoms of iron deficiency anemia are initially vague, but become more noticeable as the condition worsens.
- Diagnosis involves complete blood count (CBC), iron level tests, and blood smear tests to assess red blood cells and hemoglobin levels.
- Treatment includes diet changes, iron-rich foods, iron supplementation, and preventive measures.
- The pathophysiology involves the role of red blood cells in transporting oxygen and removing carbon dioxide, facilitated by hemoglobin containing iron.
- Low iron levels result in less hemoglobin and red blood cells, leading to decreased oxygen in the body.
- Causes of iron deficiency anemia include poor intake of iron, absorption problems in the gut, and iron loss from blood loss.
- Major signs and symptoms of iron deficiency anemia can be remembered using the mnemonic "low iron": lethargy, overexertion, and shortness of breath due to low oxygen levels.
- Risk factors for iron deficiency anemia include pregnancy, poor diet, intestinal surgery, celiac disease, heavy menstruation, and gastrointestinal bleeding.
- Patients with iron deficiency anemia may initially experience vague symptoms, but as the condition worsens, symptoms become more noticeable.
- Diagnosis of iron deficiency anemia involves CBC, iron level tests, and blood smear tests to assess red blood cells and hemoglobin levels.
