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.

Explanation
A) This choice is incorrect because folate-deficiency anemia is associated with a deficiency of folic acid, often caused by poor dietary intake or malabsorption, but not specifically linked to alcoholism.
B) This choice is incorrect because hemolytic anemia is characterized by the destruction of red blood cells and is not directly related to alcoholism.
C) This choice is incorrect because sickle cell anemia is a genetic disorder and is not caused by alcohol consumption.
D) This choice is correct. Macrocytic anemia is commonly associated with alcoholism due to the direct toxic effects of alcohol on bone marrow, resulting in the production of larger-than-normal red blood cells (macrocytes).
Correct Answer is B
Explanation
A) This choice is incorrect because vitamin A deficiency does not cause megaloblastic anemia.
B) This choice is correct because megaloblastic anemia is typically caused by a deficiency of vitamin B12 or folic acid, which are essential for normal red blood cell production.
C) This choice is incorrect because vitamin C deficiency leads to scurvy, a condition unrelated to megaloblastic anemia.
D) This choice is incorrect because vitamin D deficiency can lead to conditions like rickets, but it does not cause megaloblastic anemia.
