A high RDW value suggests:
A) Uniform RBC size
B) Increased oxygen-carrying capacity
C) Variation in RBC size
D) Low hemoglobin levels Correct Answer: C) Variation in RBC size
Rationale: An elevated RDW indicates anisocytosis, which is common in mixed anemias or
conditions with uneven RBC production and destruction.
Which anemia is characterized by low MCV, low MCHC, and high RDW?
A) Normocytic anemia
B) Macrocytic anemia
C) Microcytic, hypochromic anemia
D) Hemolytic anemia Correct Answer: C) Microcytic, hypochromic anemia
Rationale: Microcytic, hypochromic anemia typically presents with low MCV, low MCHC, and
high RDW, often seen in iron deficiency anemia.
What does a low serum iron level typically indicate?
,A) Hemochromatosis
B) Iron deficiency anemia
C) Hemolytic anemia
D) Aplastic anemia Answer:
B) Iron deficiency anemia
Rationale:
Low serum iron is most commonly associated with iron deficiency anemia, as the body has
insufficient iron for red blood cell production.
Which of the following conditions can cause an elevated ferritin level?
A) Iron deficiency anemia
B) Anemia of chronic illness
C) Sickle cell anemia
D) Aplastic anemia Answer:
B) Anemia of chronic illness
Rationale:
Ferritin is an acute-phase reactant, meaning it can be elevated in conditions like anemia of
chronic illness due to inflammation or infection, even when iron stores are low.
, A high total iron-binding capacity (TIBC) is most commonly seen in which condition?
A) Iron deficiency anemia
B) Hemolytic anemia
C) Aplastic anemia
D) Anemia of chronic illness Answer:
A) Iron deficiency anemia
Rationale:
TIBC is typically elevated in iron deficiency anemia as the body attempts to increase the
transport of iron by producing more transferrin.
What does a low transferrin saturation indicate?
A) Iron overload
B) Iron deficiency anemia
C) Hemolytic anemia
D) Aplastic anemia Answer:
B) Iron deficiency anemia
Rationale:
Low transferrin saturation (less than 20%) is commonly found in iron deficiency anemia, as
there is not enough iron available to saturate transferrin.
