- High MCV with low B12 level
Correct answer: Low MCV with low ferritin and high TIBC
Iron deficiency anemia presents with microcytic (low MCV), hypochromic anemia, low ferritin, and elevated TIBC reflecting low iron stores.
Question 5: A 7-year-old is brought in for enuresis. He has never been consistently dry at night. What is the most appropriate initial management?
