Question

The laboratory tests performed on a patient indicate macrocytosis, anemia, leukopenia, and thrombocytopenia. Which of the following disorders is the patient most likely to have?

A. Iron-deficiency anemia
B. Vitamin B12 deficiency
C. Hemolytic anemia
D. Sickle cell disease

Answer 1

Given the symptoms of macrocytosis, anemia, leukopenia, and thrombocytopenia, the patient is most likely suffering from a Vitamin B12 deficiency.

Step-by-step explanation:

The patient is most likely to have Vitamin B12 deficiency based on the laboratory tests indicating macrocytosis, anemia, leukopenia, and thrombocytopenia. These symptoms correspond with the effects of a Vitamin B12 deficiency, which includes faulty or decreased red blood cell (RBC) production and can lead to the presence of abnormally large RBCs, known as macrocytosis, as well as decrease in white blood cells and platelets, resulting in leukopenia and thrombocytopenia respectively. Vitamin B12 is essential for proper RBC formation, neurological function, and DNA synthesis; hence a deficiency can have widespread effects.
