Which of the following types of vitamin or mineral deficiency can cause megaloblastic anemia and is associated with lower extremity paresthesias?

  • A. Vitamin B12
  • B. Folate
  • C. Iron
  • D. Vitamin K
Correct Answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 deficiency can lead to megaloblastic anemia and neurological symptoms, including lower extremity paresthesias. Folate deficiency can also cause megaloblastic anemia but typically does not present with neurological symptoms. Iron deficiency leads to microcytic anemia, not megaloblastic anemia. Vitamin K deficiency is associated with coagulation abnormalities, not megaloblastic anemia.
