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 A
Explanation
A) This choice is correct. Taking iron supplements with orange juice or other vitamin C-rich beverages enhances iron absorption due to the presence of vitamin C, which facilitates the absorption of non-heme iron.
B) This choice is incorrect because milk can inhibit iron absorption when taken with iron supplements.
C) This choice is incorrect because tea, especially black tea, contains tannins that can hinder iron absorption.
D) This choice is incorrect because carbonated water does not enhance iron absorption.
Correct Answer is B
Explanation
A) This choice is incorrect because whole-grain bread contains phytates that can inhibit iron absorption, and although eggs enhance non-heme iron absorption, the combination with whole-grain bread may not be as effective as other options.
B) This choice is correct. Red meat is a rich source of heme iron, which is well-absorbed, and dairy products are sources of calcium that do not significantly inhibit heme iron absorption. Combining heme iron with calcium-rich foods can help optimize iron uptake.
C) This choice is incorrect because although spinach is a source of non-heme iron, it also contains substances such as oxalates that can hinder iron absorption. Nuts, while being nutritious, do not specifically enhance iron absorption.
D) This choice is incorrect because both lentils and beans are sources of non-heme iron, and the combination does not provide a significant enhancer of iron absorption.
