FNP Review – Anemia/Hematology (2026–2027)
– Hematology Exam Questions and Answers
Introduction
This document contains a collection of hematology exam questions
with verified answers focused on anemia and related hematologic
disorders. It covers iron deficiency anemia, vitamin B12 and folate
deficiency, hemolytic anemias, thalassemia, sickle cell disease,
aplastic anemia, laboratory interpretation, and common treatment
approaches. The material is presented in a question-and-answer
format, making it suitable for exam revision and self-assessment. It
also includes key laboratory findings, diagnostic tests, and clinical
presentations frequently tested in nursing and medical
examinations.
Exam Questions and Answers
1: What is the most common cause of iron deficiency anemia in
adults?--- correct precise answer ---
The most common cause of iron deficiency anemia in adults is
chronic blood loss, often from gastrointestinal bleeding or heavy
menstrual periods.

2: What laboratory test is the most sensitive indicator of iron
deficiency anemia?--- correct precise answer ---
Serum ferritin is the most sensitive indicator of iron deficiency
anemia, as it reflects the bodys iron stores.
3: What is the primary function of hemoglobin in the blood?---
correct precise answer ---
The primary function of hemoglobin is to transport oxygen from
the lungs to the tissues and to carry carbon dioxide from the tissues
back to the lungs.
4: What is the significance of a high reticulocyte count in a patient
with anemia?--- correct precise answer ---
A high reticulocyte count in a patient with anemia indicates that
the bone marrow is responding to anemia by producing more red
blood cells, suggesting a regenerative process.
5: What are the characteristic laboratory findings in pernicious
anemia?--- correct precise answer ---
In pernicious anemia, laboratory findings typically include
macrocytic anemia, low serum vitamin B12 levels, and the presence
of anti-intrinsic factor antibodies.
6: What is the role of intrinsic factor in vitamin B12 absorption?---
correct precise answer ---
Intrinsic factor, produced by the gastric parietal cells, binds to
vitamin B12 and facilitates its absorption in the ileum.

7: What is the most common cause of anemia in hospitalized
patients?--- correct precise answer --- The most common cause of
anemia in hospitalized patients is anemia of chronic disease, often
associated with chronic infections, inflammatory diseases, or
malignancies.
8: How does sickle cell anemia affect red blood cells?--- correct
precise answer ---
In sickle cell anemia, a genetic mutation causes hemoglobin to form
stiff rods within the red blood cells, leading to their characteristic
sickle shape, which can cause blockages in blood vessels and
hemolysis.
9: What is the typical treatment approach for iron deficiency
anemia?--- correct precise answer ---
The typical treatment for iron deficiency anemia includes oral iron
supplementation, dietary modifications to increase iron intake, and
addressing the underlying cause of the deficiency.
10: What is thalassemia, and how is it classified?--- correct precise
answer ---
Thalassemia is a genetic disorder characterized by reduced
production of one or more globin chains in hemoglobin. It is
classified into alpha and beta thalassemia, depending on which
globin chain is affected.
