Hematologic System

Hematology covers anemias, coagulation disorders, hemoglobinopathies, and hematologic malignancies. Index-based anemia classification and clotting-cascade logic solve a large share of these questions.

What is covered

Topics inside this content area.

These topics describe the scope students most often review for this part of PANCE. Treat them as a study checklist rather than an exhaustive list of what a single exam form can sample.

Microcytic, normocytic, and macrocytic anemias: Iron studies, B12 and folate patterns, and hemolysis markers as sorting tools.
Hemoglobinopathies: Sickle cell disease and thalassemias with their electrophoresis patterns.
Coagulation disorders: Hemophilias, von Willebrand disease, and platelet versus factor bleeding patterns.
Thrombotic disorders and anticoagulation: Inherited thrombophilias and monitoring rules for each anticoagulant class.
Hematologic malignancies: Leukemias, lymphomas, and myeloma with their marker and smear buzzwords.
Transfusion medicine: Product selection and recognition of transfusion reactions.

Study tips

How to practice Hematologic.

Section-specific guidance that follows from how this material is usually tested.

Classify every anemia stem by MCV before reading the answer choices.
Contrast platelet-type versus factor-type bleeding with two example diseases each.
Keep smear findings on image cards; visual recall is what the exam samples.

Sample Hematologic questions

Practice questions, not yet expert-reviewed

Original practice questions written to the published framework for this section. No expert has reviewed them, and they are not taken from any official exam. Try each one before you open the answer.

Question 1Foundational
A microcytic anemia shows a low serum ferritin, an elevated total iron-binding capacity, and a low transferrin saturation. Which condition does this pattern indicate?
1. AIron deficiency anemia
2. BAnemia of chronic disease
3. CBeta thalassemia minor
4. DSideroblastic anemia
Show answer
Answer: A. Iron deficiency anemia
Depleted iron stores lower ferritin while the liver makes more transferrin, which raises total iron-binding capacity and lowers transferrin saturation. Anemia of chronic disease is the tempting distractor because it is also microcytic, but there the iron is sequestered rather than absent, so ferritin is normal or high and the binding capacity is low.
Key insight: Ferritin low and binding capacity high means the iron is gone; ferritin high and binding capacity low means the iron is locked away.
Question 2Foundational
Deficiency of which vitamin causes a macrocytic anemia together with peripheral neuropathy and loss of vibration and position sense?
1. AFolate
2. BVitamin B12
3. CIron
4. DVitamin K
Show answer
Answer: B. Vitamin B12
Vitamin B12 is required both for DNA synthesis in erythroid precursors and for myelin maintenance, so its deficiency produces megaloblastic anemia plus subacute combined degeneration of the posterior and lateral columns. Folate deficiency is the tempting distractor because it causes an identical blood picture, but it spares the nervous system.
Key insight: Macrocytic anemia with neurologic findings is B12; macrocytic anemia without them is usually folate.
Question 3Intermediate
What is the most common inherited bleeding disorder, typically causing mucocutaneous bleeding and heavy menses with a normal platelet count?
1. AHemophilia A
2. BHemophilia B
3. CVon Willebrand disease
4. DImmune thrombocytopenia
Show answer
Answer: C. Von Willebrand disease
Von Willebrand factor mediates platelet adhesion, so its deficiency produces a platelet-type bleeding pattern of epistaxis, easy bruising, and menorrhagia despite a normal platelet count. Hemophilia A is the tempting distractor, but factor VIII deficiency is X-linked and far less common and causes deep joint and muscle bleeding rather than mucosal bleeding.
Key insight: Mucosal bleeding points to platelets or their glue; deep joint bleeding points to the clotting factors.
Question 4Intermediate
Which coagulation study is used to monitor the anticoagulant effect of intravenous unfractionated heparin?
1. AProthrombin time with international normalized ratio
2. BActivated partial thromboplastin time
3. CBleeding time
4. DFibrinogen level
Show answer
Answer: B. Activated partial thromboplastin time
Unfractionated heparin potentiates antithrombin against thrombin and factor Xa, prolonging the intrinsic pathway that the activated partial thromboplastin time measures. The prothrombin time with international normalized ratio is the tempting distractor because it is the familiar anticoagulation test, but it monitors warfarin through the extrinsic pathway.
Key insight: Heparin goes with the partial thromboplastin time; warfarin goes with the prothrombin time and international normalized ratio.
Question 5Advanced
Which cell identified on lymph node biopsy is the pathologic hallmark of classic Hodgkin lymphoma?
1. AReed-Sternberg cell
2. BSmudge cell
3. CAtypical reactive lymphocyte
4. DPlasma cell with Russell bodies
Show answer
Answer: A. Reed-Sternberg cell
The Reed-Sternberg cell is a large binucleated cell with prominent nucleoli that must be present in the appropriate cellular background to diagnose classic Hodgkin lymphoma. Smudge cells are the tempting distractor because they are also a classic morphologic buzzword, but they appear on the peripheral smear in chronic lymphocytic leukemia.
Key insight: Painless cervical lymphadenopathy with night sweats plus Reed-Sternberg cells on biopsy is classic Hodgkin lymphoma.
