A nurse is assessing a client diagnosed with anemia. Which of the following statements about anemia is correct?
Anemia is characterized by an increase in red blood cell production.
Anemia is primarily caused by an excess of iron in the body.
Anemia results in a decreased oxygen-carrying capacity of the blood.
Anemia is a viral infection affecting the bone marrow.
The Correct Answer is C
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.

Correct Answer is D
Explanation
A) This choice is incorrect because while blood pressure monitoring is essential for clients with chronic kidney disease, it is not specifically related to ESA therapy.
B) This choice is incorrect because serum potassium levels are important in chronic kidney disease, but they are not directly related to ESA therapy.
C) This choice is incorrect because dietary sodium intake is important in managing fluid balance in chronic kidney disease, but it is not directly related to ESA therapy.
D) This choice is correct. ESA therapy stimulates the production of red blood cells, and adequate iron levels are necessary for this process. Clients with chronic kidney disease often have decreased iron levels due to various factors, and iron supplementation is crucial for the success of ESA therapy.
Questions
Correct Answer is A
Explanation
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.
