Question 1 of 5
A nurse is caring for a client who the provider suspects might have pernicious anemia. The nurse should expect the provider to prescribe which of the following diagnostic tests?
Correct Answer: A
Rationale: The correct answer is A: Schilling test. Pernicious anemia is caused by vitamin B12 deficiency, often due to poor absorption. The Schilling test is specifically used to diagnose pernicious anemia by evaluating the body's ability to absorb vitamin B12. The test involves giving the patient a small amount of radioactive vitamin B12 to determine how well it is absorbed and utilized by the body. This test helps to differentiate pernicious anemia from other causes of B12 deficiency.
Choice B (Complete blood count) is a general test that may show abnormalities in red blood cells seen in anemia, but it does not specifically diagnose pernicious anemia.
Choice C (Vitamin B12 level) alone may not differentiate between pernicious anemia and other causes of B12 deficiency.
Choice D (Bone marrow biopsy) is not typically necessary for diagnosing pernicious anemia and is more invasive compared to the Schilling test.
