What condition is characterized by a lower than normal number of red blood cells or hemoglobin?

• A. Anemia
• B. Leukemia
• C. Polycythemia
• D. Thrombocytopenia

Answer: (A)

Anemia is characterized by a lower than normal number of red blood cells or a decrease in the amount of hemoglobin in the blood. This condition leads to reduced oxygen transport throughout the body, resulting in symptoms such as fatigue, weakness, and pallor. Anemia can be caused by various factors including nutritional deficiencies (like iron, vitamin B12, or folate), chronic diseases, or bone marrow issues. Understanding this condition is crucial for CNAs, as it affects patient care and the monitoring of symptoms related to oxygenation and overall health. In contrast, leukemia refers to cancer of the blood or bone marrow, leading to abnormal white blood cell proliferation. Polycythemia is the opposite of anemia, characterized by an increased number of red blood cells. Thrombocytopenia involves a low platelet count, which relates to bleeding risks rather than red blood cell levels.
