A client with anemia is undergoing a Schilling test to determine the cause of the condition. The nurse should recognize that this test is used to diagnose which type of anemia?
Iron-deficiency anemia
Pernicious anemia
Aplastic anemia
Hemolytic anemia
The Correct Answer is B
A) This choice is incorrect because the Schilling test is not used to diagnose iron-deficiency anemia. It is primarily used to diagnose pernicious anemia, a type of megaloblastic anemia caused by vitamin B12 deficiency.
B) This choice is correct. The Schilling test is used to diagnose pernicious anemia by assessing the body's ability to absorb vitamin B12 from the digestive system.
C) This choice is incorrect because the Schilling test is not used to diagnose aplastic anemia. Aplastic anemia is diagnosed through other means, such as bone marrow biopsy and blood tests.
D) This choice is incorrect because the Schilling test is not used to diagnose hemolytic anemia. Hemolytic anemia is diagnosed through blood tests and other assessments to determine red blood cell destruction.

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.
Correct Answer is A
Explanation
A) This choice is correct. Serum ferritin levels are used to assess the body's iron stores. Ferritin is a protein that stores iron in the body, and low levels of serum ferritin indicate iron deficiency.
B) This choice is incorrect because the erythrocyte sedimentation rate (ESR) is a nonspecific indicator of inflammation and is not directly related to iron stores.
C) This choice is incorrect because total iron-binding capacity (TIBC) measures the amount of iron that can be bound to transferrin, a protein that transports iron in the blood, but it does not directly assess iron stores.
D) This choice is incorrect because the white blood cell count (WBC) is not directly related to iron stores or the evaluation of anemia.
