The blood smear of a patient with iron-deficiency anemia shows a decreased hemoglobin level and small red blood cells. These cells are described as which of the following?

This describes red blood cells that are larger than normal (macrocytic) and have varying levels of hemoglobin saturation (polychromic). Macrocytic cells are typically associated with conditions like vitamin B12 or folate deficiency, which is not relevant in iron-deficiency anemia, where cells are actually smaller.

While the cells are indeed microcytic, "normochromic" implies that the hemoglobin content is normal. In iron-deficiency anemia, the hemoglobin level is decreased, making this description inaccurate for the condition.

This term refers to red blood cells that are of normal size (normocytic) but have reduced hemoglobin (hypochromic). In iron-deficiency anemia, the red blood cells are actually smaller than normal, thus this option does not accurately reflect the condition.

This describes red blood cells that are of normal size (normocytic) and have varying levels of hemoglobin (polychromic). This is typically associated with conditions like hemolytic anemia, which does not apply to iron-deficiency anemia characterized by smaller, hypochromic cells.
