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 and is diagnosed through a complete blood count (CBC) and iron level tests.
The body uses iron to produce hemoglobin, and low iron levels lead to fewer red blood cells, less hemoglobin, and reduced oxygen supply to the body.
Signs and symptoms of iron deficiency anemia may initially be vague, but as it progresses, they become more noticeable, including fatigue and shortness of breath.
Diagnosis involves CBC, iron level, and blood smear tests to examine red blood cells' appearance.
Treatment includes dietary changes, iron-rich foods, iron supplementation, and preventive measures.
In iron deficiency anemia, low iron levels lead to less hemoglobin and red blood cells, resulting in reduced oxygen in the body.
Causes of iron deficiency anemia include poor intake (e.g., pregnancy, poor diet, vegetarianism), absorption problems (e.g., intestinal surgery, celiac disease), and blood loss (e.g., heavy menstruation, GI bleeding).
Major signs and symptoms of iron deficiency anemia can be remembered using the mnemonic "low iron," including lethargy, overexertion, and shortness of breath due to low oxygen transport.
Hemoglobin, a protein containing iron, plays a crucial role in transporting oxygen and carbon dioxide in red blood cells.
Iron deficiency anemia can be caused by various factors, including poor intake, absorption problems, and blood loss.
Signs and symptoms of iron deficiency anemia include lethargy, overexertion, and shortness of breath due to low oxygen levels in the body.
