Gastrointestinal Disorders

• Cirrhosis often results in clotting abnormalities, leading to prolonged hemorrhage. Patients with severe cirrhosis undergoing dental therapy may experience extended bleeding times. [Q0027]
• Erosion of maxillary central incisors is characteristic of acid reflux seen in pyloric stenosis. This erosion is due to the frequent exposure of teeth to stomach acid. [Q0564]

Hematology

• Koilonychia, or spoon-shaped nails, is a classic sign of iron deficiency anemia. This condition can indicate chronic blood loss or insufficient dietary iron intake. [Q5616]
• The maximum acceptable INR level for tooth extraction is generally 3. Monitoring INR levels helps ensure safe dental procedures for patients on anticoagulants. [Q5643]
• The minimum platelet count required for tooth extraction is generally 50,000 per µL. Ensuring adequate platelet levels is crucial for preventing excessive bleeding. [Q5651]
• The minimum leukocyte count required for extractions is typically 3,000 per µL. Adequate leukocyte levels are important for reducing the risk of infection post-extraction. [Q5652]
• Von Willebrand Disease is the most common inherited bleeding disorder in humans. Patients with this condition may require special care during dental procedures. [Q5670]
• Acute lymphoblastic leukemia (ALL) is the most common type of leukemia in children. Early diagnosis and treatment are critical for improving outcomes. [Q5672]
• Leukocytosis is the term for an excessive number of white blood cells. This condition can indicate an underlying infection or inflammatory response. [Q5797]
• Vitamin K deficiency affects Factors II, VII, IX, and X. Adequate vitamin K is essential for proper blood clotting and prevention of bleeding disorders. [Q5901]
• Hemophilia C causes the least bleeding into joints. This type of hemophilia is less severe compared to Hemophilia A and B. [Q5941]
• Surgicel (oxidized cellulose) is a resorbable hemostatic agent that can be left in situ. It helps control bleeding during and after surgical procedures. [Q6028]
• Hemoglobin electrophoresis is used to diagnose hemoglobinopathies like sickle cell disease or thalassemia, which are common in Afro-Caribbean populations. Accurate diagnosis is essential for proper management. [Q6061]
• Patients with a history of DVT are at higher risk of developing DVT under general anesthesia. Preventive measures should be taken to reduce this risk during surgery. [Q6097]
• Patients on anticoagulants are most likely to experience bleeding after extraction. Careful planning and monitoring are necessary to manage these patients safely. [Q6098]
• Young erythrocytes are called reticulocytes. The presence of reticulocytes indicates active erythropoiesis in the bone marrow. [Q6129]

Immunology

• Secretory immunoglobulins are typically IgA, not IgM. IgA plays a crucial role in mucosal immunity. [Q4027]
• Neutrophils are the primary cells involved in the acute inflammatory response. They are the first responders to infection and tissue injury. [Q5565]
• Approximately 30% of the population has type 1 hypersensitivity. This type of allergic reaction involves IgE antibodies. [Q5704]
• A toxoid vaccine is made from inactivated toxins and is used to immunize against diseases caused by those toxins. Examples include vaccines for diphtheria and tetanus. [Q5744]
• The hepatitis B vaccine is a subunit vaccine, containing purified antigens. This type of vaccine helps induce immunity without causing the disease. [Q5758]
• Latex allergy is a Type I hypersensitivity reaction. It can cause severe allergic symptoms upon exposure to latex products. [Q5799]
• Latex allergy is a Type I hypersensitivity reaction. It can cause symptoms such as itching, swelling, and anaphylaxis. [Q5803]
• Anaphylaxis is characterized by swelling, difficulty breathing, rash, hives, and other symptoms, making “All of the above” the correct answer. Immediate medical intervention is required. [Q5807]
• Neutrophils are most abundant during bacterial infections. They play a key role in defending the body against bacterial pathogens. [Q5823]
