Practice Question
A 36-year-old female arrives at the clinic with reports of fatigue, palpitations, ringing in the ears, and excessive tiredness with activity.
Answer Choices:
Rationale:
🔷 Malabsorption syndrome is a common cause of Vitamin B12 deficiency anemia (e.g., pernicious anemia, gastric bypass) and Folic acid deficiency anemia (intestinal malabsorption), but not typical in iron deficiency anemia, which is usually due to blood loss.
🔷 Decreased hemoglobin and hematocrit levels occur in all three anemias because they share a common outcome—reduced red blood cell production or loss, leading to impaired oxygen transport.
🔷 Dietary deficiency can result in any of the three: Vitamin B12 deficiency (strict vegan diet), Folic acid deficiency (poor nutrition), and Iron deficiency anemia (low iron intake or chronic blood loss with inadequate replacement).
🔷 Uptake impeded by medications is typical for Vitamin B12 deficiency (proton pump inhibitors, metformin) and Folic acid deficiency (methotrexate, anticonvulsants) but not for iron, which is more affected by diet or bleeding.
🔷 Chronic alcoholism is strongly linked to Folic acid deficiency anemia due to poor dietary intake, impaired folate metabolism, and direct toxic effects on bone marrow.
