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 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.
Correct Answer is A
Explanation
A) This choice is correct. Folate-deficiency anemia can present with fatigue, weakness, and glossitis (inflammation of the tongue), leading to a red, sore tongue.
B) This choice is incorrect because hemolytic anemia is characterized by the destruction of red blood cells, and it does not specifically cause a red, sore tongue.
C) This choice is incorrect because sickle cell anemia primarily causes vaso-occlusive crises and pain, not symptoms related to the tongue.
D) This choice is incorrect because iron-deficiency anemia does not cause glossitis; however, it may present with fatigue and weakness.
