A72-year-old woman with complaints of increasing fatigue has completed a series of fecal occult blood tests that indicate the presence of blood in her stool. which of the following health problems is likely to accompany this patient's gastrointestinal bleed?
a) hemolytic anemia
b) aplastic anemia
c) iron-deficiency anemia
d) megaloblastic anemia

C) Iron-deficiency anemia

Explanation:

Iron anemia or deficiency of iron is a condition in which blood lacks adequate amount of healthy red blood cells. In this condition the body does not contain enough iron so as to produce hemoglobin. The blood loss from the body, inability of the body to absorb the iron from the food, pregnancy all can also be the cause of iron- deficiency anemia. For the identification of this condition the blood can be seen in the stool,brittle nails, weakness, extreme fatigue, and pale skin can be looked upon.

Thus C is the correct option.
