A nurse is caring for a client with anemia. Which diagnostic test should the nurse anticipate to determine the cause of the anemia and assess the size and shape of the red blood cells?
Hemoglobin electrophoresis
Reticulocyte count
Peripheral blood smear
Serum iron levels
The Correct Answer is C
A) This choice is incorrect because hemoglobin electrophoresis is used to identify abnormal hemoglobin types, not to assess the size and shape of red blood cells.
B) This choice is incorrect because a reticulocyte count measures the number of immature red blood cells in the blood and helps determine if the bone marrow is responding appropriately to anemia, but it does not assess the size and shape of red blood cells.
C) This choice is correct. A peripheral blood smear is used to examine the morphology of red blood cells, including their size, shape, and appearance. It can help identify different types of anemia and determine the cause of anemia.
D) This choice is incorrect because serum iron levels provide information about iron status but do not directly assess the size and shape of red blood cells.

Correct Answer is A
Explanation
A) This choice is correct. Headaches and dizziness are common symptoms of iron-deficiency anemia due to decreased oxygen delivery to the brain.
B) This choice is incorrect because headaches and dizziness are not specific to hemolytic anemia.
C) This choice is incorrect because pernicious anemia is primarily associated with neurological symptoms such as tingling and difficulty maintaining balance, but not specifically headaches and dizziness.
D) This choice is incorrect because headaches and dizziness are not directly related to aplastic anemia. Aplastic anemia primarily affects the bone marrow and leads to decreased production of all blood cells, rather than causing symptoms specific to the brain.
Questions
Correct Answer is B
Explanation
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.
