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?

A) This choice is incorrect because polyuria, or increased urination, is not a common symptom of anemia. It may be associated with other conditions like diabetes.

B) This choice is incorrect because increased appetite is not typically associated with anemia. In fact, some clients with anemia may have a reduced appetite due to fatigue and weakness.

C) This choice is correct. Anemia leads to decreased oxygen-carrying capacity of the blood, which can result in shortness of breath, especially during physical exertion.

D) This choice is incorrect because anemia causes fatigue and decreased energy levels, not increased energy levels.

A) This choice is correct. A vegetarian diet, especially if not well-balanced and lacking in iron-rich foods, can lead to iron-deficiency anemia.

B) This choice is incorrect. Chronic kidney disease is more likely to cause anemia due to impaired erythropoietin production rather than directly causing iron deficiency.

C) This choice is incorrect. Excessive red blood cell destruction is associated with hemolytic anemia, not iron-deficiency anemia.

D) This choice is correct. Gastrointestinal bleeding, such as from peptic ulcers or inflammatory bowel disease, can lead to chronic blood loss and iron-deficiency anemia.
