A client is suspected to have anemia. The nurse advises the client to increase the intake of which dietary component to help differentiate between iron-deficiency anemia and other types of anemia?
Vitamin C
Folate
Vitamin B12
Protein
The Correct Answer is A
A) This choice is correct. Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based foods and supplements), so increasing vitamin C intake can help improve iron absorption. This can help differentiate between iron-deficiency anemia (improved iron absorption with increased vitamin C) and anemia of chronic disease (improved iron absorption with decreased vitamin C intake).
B) This choice is incorrect because increasing folate intake may help with megaloblastic anemia caused by folate deficiency, but it does not directly differentiate between iron-deficiency anemia and other types of anemia.
C) This choice is incorrect because increasing vitamin B12 intake does not help differentiate between iron-deficiency anemia and other types of anemia.
D) This choice is incorrect because increasing protein intake is important for overall health but does not directly help differentiate between iron-deficiency anemia and other types of anemia.

Correct Answer is C
Explanation
A) This choice is incorrect because hemolytic anemia typically presents with normocytic and normochromic red blood cells, as the bone marrow compensates by releasing immature red blood cells.
B) This choice is incorrect because sickle cell anemia is characterized by the presence of sickle-shaped red blood cells and is not associated with microcytic and hypochromic cells.
C) This choice is correct. Thalassemia is a type of anemia in which the synthesis of globin chains is impaired, leading to microcytic and hypochromic red blood cells.
D) This choice is incorrect because pernicious anemia is associated with macrocytic and normochromic red blood cells due to vitamin B12 deficiency.
Correct Answer is C
Explanation
A) This statement is incorrect because anemia is characterized by a decrease in red blood cell production or an abnormal decrease in hemoglobin levels, not an increase in red blood cell production.
B) This statement is incorrect because anemia is caused by a deficiency in iron, not an excess of iron.
C) This statement is correct. Anemia is characterized by a reduced number of red blood cells or a decreased hemoglobin concentration, which leads to a diminished ability of the blood to carry oxygen throughout the body.
D) This statement is incorrect. Anemia is not caused by a viral infection affecting the bone marrow; rather, it is typically caused by nutritional deficiencies, chronic diseases, or blood loss.
