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 choice is incorrect because pernicious anemia is not related to iron deficiency, so increasing iron-rich foods will not address the underlying cause.
B) This choice is incorrect because vitamin C actually enhances the absorption of vitamin B12, which is essential in pernicious anemia.
C) This choice is correct. Pernicious anemia is caused by the lack of intrinsic factor, a protein necessary for vitamin B12 absorption. Clients with pernicious anemia will require lifelong vitamin B12 supplementation, often through intramuscular injections.
D) This choice is incorrect. Leafy green vegetables are good sources of folate, which is not directly related to pernicious 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.
