Open Ended

Why is understanding molecular biology important in the study of hematological diseases such as thrombocytopenia, hemophilia, and coagulation disorders?

Multiple Choice

What is the main cause of thrombocytopenic purpura according to its definition?

• Destruction of platelets in peripheral blood

• Increased platelet production in bone marrow

• Decreased destruction of platelets

• Increased red blood cell count

Describe the appearance of platelets under a microscope and explain their significance in diagnosing thrombocytopenic purpura.

Multiple Choice

Which of the following is NOT a cause of decreased platelet production?

• Congenital conditions

• Immune-mediated destruction in peripheral blood

• Radiation exposure

Multiple Select

Select all the causes of increased platelet destruction in peripheral blood.

• Immune-mediated thrombocytopenia

• Congenital platelet structure disorders

• Bone marrow failure

• Disseminated intravascular coagulation (DIC)

Open Ended

What are the main clinical manifestations of thrombocytopenic purpura, and how do they differ between age groups and genders?

Multiple Choice

Which of the following is NOT a common symptom of immune thrombocytopenic purpura (ITP) as shown in the images?

• Petechiae on lower limbs

• Unexplained nosebleeds

• Multiple bruises on the skin

• High fever

Multiple Choice

What is the most valuable laboratory test for diagnosing immune thrombocytopenic purpura (ITP) according to the slides?

• Platelet count

• Bone marrow biopsy

• Detection of antiplatelet antibodies

• White blood cell count

Multiple Select

Which laboratory findings are typically observed in patients with immune thrombocytopenic purpura (ITP)?

• Decreased platelet count

• Increased white blood cell count

• Normal coagulation tests

• Decreased platelet lifespan

Open Ended

Explain how laboratory findings help differentiate immune thrombocytopenic purpura (ITP) from other bleeding disorders.

Open Ended

Open Ended

Describe the clinical symptoms that differentiate joint bleeds from a healthy joint in hemophilia patients.

Multiple Select

Which of the following are common symptoms observed in hemophilia patients based on the images?

• Bruising

• Swelling of joints

• Fever

• Joint bleeds

Multiple Choice

What is the prevalence rate of hemophilia A among hemophilia cases worldwide?

• 10% - 15%

• 20% - 25%

• 80% - 85%

• 50% - 60%

Open Ended

Explain the role of factor VIII and its genetic location in the process of blood clotting.

Multiple Choice

Which chromosome contains the gene for coagulation factor IX, and what is its significance in hemophilia B?

• Chromosome X; it causes hemophilia B when mutated.

• Chromosome Y; it causes hemophilia A when mutated.

• Chromosome 22; it is unrelated to hemophilia.

• Chromosome 8; it causes hemophilia C when mutated.

Open Ended

Describe the types of genetic mutations commonly found in hemophilia and how they differ between factor VIII and factor IX.

Multiple Choice

What is the principle behind using PCR-RFLP to detect hemophilia carriers?

• It identifies specific polymorphisms in the gene of interest.

• It amplifies all genes in the genome.

• It sequences the entire genome.

• It detects protein levels in blood samples.

Multiple Choice

Which requirements must be met to perform PCR-RFLP for hemophilia carrier detection?

• Mother must be a confirmed carrier and both parents' polymorphisms must be tested.

• Only the father's polymorphism needs to be tested.

• No family history is required.

• Only the patient's DNA is needed.

Multiple Choice

Who is indicated for hemophilia carrier testing according to the guidelines?

• Any woman with a family history of hemophilia who wants to determine carrier status.

• Any man with hemophilia.

• Any child with bleeding disorders.

• Any person with no family history of hemophilia.

Multiple Choice

Which of the following is a bleeding disorder characterized by a deficiency of clotting factors?

• Thrombocytopenia

• Hemophilia

• Leukemia

• Anemia
