A client is diagnosed with anemia, and laboratory results show macrocytic and normochromic red blood cells. A nurse suspects a specific type of anemia based on these findings. Which type is most likely to be associated with this result?
Iron-deficiency anemia
Aplastic anemia
Sickle cell anemia
Megaloblastic anemia
The Correct Answer is D
A) This choice is incorrect because iron-deficiency anemia is associated with microcytic and hypochromic red blood cells, not macrocytic and normochromic cells.
B) This choice is incorrect because aplastic anemia typically presents with normocytic and normochromic red blood cells.
C) This choice is incorrect because sickle cell anemia does not cause macrocytic and normochromic red blood cells.
D) This choice is correct. Megaloblastic anemia is characterized by macrocytic (large) and normochromic (normal color) red blood cells, which are the result of impaired DNA synthesis during red blood cell production. This condition is often caused by vitamin B12 or folate deficiency.

Correct Answer is D
Explanation
A) This choice is incorrect because folate-deficiency anemia is associated with a deficiency of folic acid, often caused by poor dietary intake or malabsorption, but not specifically linked to alcoholism.
B) This choice is incorrect because hemolytic anemia is characterized by the destruction of red blood cells and is not directly related to alcoholism.
C) This choice is incorrect because sickle cell anemia is a genetic disorder and is not caused by alcohol consumption.
D) This choice is correct. Macrocytic anemia is commonly associated with alcoholism due to the direct toxic effects of alcohol on bone marrow, resulting in the production of larger-than-normal red blood cells (macrocytes).
Correct Answer is D
Explanation
A) This choice is incorrect because coffee contains substances that can inhibit iron absorption.
B) This choice is incorrect because tea, especially black tea, contains tannins that can hinder iron absorption.
C) This choice is incorrect because water does not enhance iron absorption.
D) This choice is correct. Orange juice, or any other vitamin C-rich beverage, enhances the absorption of non-heme iron found in supplements and plant-based foods.
