Anemia
Anemia ( 15 Questions)
Which of the following factors should the nurse include as potential causes of iron-deficiency anemia? (Select all that apply.)
Chronic gastrointestinal bleeding is a common cause of iron-deficiency anemia. Blood loss from the gastrointestinal tract leads to the loss of iron, ultimately depleting iron stores in the body and impairing hemoglobin synthesis.
High serum iron levels are not a potential cause of iron-deficiency anemia. Iron-deficiency anemia is characterized by low serum iron levels, as the body lacks sufficient iron to produce hemoglobin.
Inadequate dietary intake of iron can lead to iron-deficiency anemia, especially in individuals who do not consume enough iron-rich foods. A lack of dietary iron can result in reduced iron absorption and insufficient iron stores in the body.
Elevated serum ferritin levels are not a potential cause of iron-deficiency anemia. In fact, elevated serum ferritin levels are more indicative of iron overload conditions rather than iron deficiency.
Increased erythropoietic activity can be a compensatory response to iron-deficiency anemia. When the body senses low oxygen-carrying capacity due to reduced hemoglobin levels, it may increase erythropoietin production, leading to the production of more red blood cells (erythropoiesis) in an attempt to improve oxygen delivery to tissues.
Choice A rationale:
Chronic gastrointestinal bleeding is a common cause of iron-deficiency anemia.
Blood loss from the gastrointestinal tract leads to the loss of iron, ultimately depleting iron stores in the body and impairing hemoglobin synthesis.
Choice B rationale:
High serum iron levels are not a potential cause of iron-deficiency anemia.
Iron-deficiency anemia is characterized by low serum iron levels, as the body lacks sufficient iron to produce hemoglobin.
Choice C rationale:
Inadequate dietary intake of iron can lead to iron-deficiency anemia, especially in individuals who do not consume enough iron-rich foods.
A lack of dietary iron can result in reduced iron absorption and insufficient iron stores in the body.
Choice D rationale:
Elevated serum ferritin levels are not a potential cause of iron-deficiency anemia.
In fact, elevated serum ferritin levels are more indicative of iron overload conditions rather than iron deficiency.
Choice E rationale:
Increased erythropoietic activity can be a compensatory response to iron-deficiency anemia.
When the body senses low oxygen-carrying capacity due to reduced hemoglobin levels, it may increase erythropoietin production, leading to the production of more red blood cells (erythropoiesis) in an attempt to improve oxygen delivery to tissues.
