উত্তর
সঠিক উত্তর: ক
Low hemoglobin with high reticulocyte count

A hallmark characteristic of megaloblastic anemia is:
  1. ক
    Microcytic, hypochromic red blood cells
  2. খ
    Increased reticulocyte count

  4. ঘ
    Normal vitamin B12 and folate levels
সঠিক উত্তর: গ
Hypersegmented neutrophils
উত্তর
সঠিক উত্তর: গ
Hypersegmented neutrophils
গ
ব্যাখ্যা
Megaloblastic anemia is primarily caused by impaired DNA synthesis, most commonly due to vitamin B12 or folate deficiency. This leads to ineffective erythropoiesis and the presence of abnormally large red blood cell precursors (megaloblasts) in the bone marrow. A key peripheral blood smear finding is hypersegmented neutrophils (five or more lobes), which are characteristic of defective nuclear maturation in granulocytes.
৩২.
Which of the following is a common neurological manifestation of vitamin B12 deficiency in megaloblastic anemia?
  1. ক
    Tetany

    Tremors
সঠিক উত্তর: খ
Peripheral neuropathy
উত্তর
সঠিক উত্তর: খ
Peripheral neuropathy
খ
ব্যাখ্যা
While both vitamin B12 and folate deficiencies cause megaloblastic anemia, only vitamin B12 deficiency typically leads to neurological symptoms. These can include peripheral neuropathy, subacute combined degeneration of the spinal cord (affecting posterior and lateral columns), paresthesias, gait disturbances, and even cognitive impairment. Folate deficiency does not cause these specific neurological issues.
৩৩.
Which of the following is a common clinical presentation in a patient with severe aplastic anemia?

  4. ঘ
    Bone pain
সঠিক উত্তর: খ
Frequent infections
উত্তর
সঠিক উত্তর: খ
Frequent infections
খ
ব্যাখ্যা
Due to severe neutropenia (a component of pancytopenia), patients with aplastic anemia are highly susceptible to infections, which can be life-threatening. Anemia leads to fatigue and pallor, while thrombocytopenia causes bleeding tendencies (e.g., petechiae, ecchymoses, mucosal bleeding).

উত্তর
সঠিক উত্তর: খ
A doughy abdomen
খ
ব্যাখ্যা
Abdominal tuberculosis (TB) can affect any part of the gastrointestinal tract, peritoneum, mesentery, or abdominal lymph nodes. A "doughy" abdomen on palpation, often with tenderness, is a classical but not always present sign, particularly in peritoneal TB due to thickened omentum and adhesions. Other common features include chronic abdominal pain, weight loss, fever, and ascites.

উত্তর
সঠিক উত্তর: খ
Spontaneous bacterial peritonitis
খ
ব্যাখ্যা
Chronic liver disease (CLD) is a broad term encompassing various conditions leading to progressive liver damage. Decompensation signifies the failure of the liver to perform its essential functions, often leading to complications like ascites, hepatic encephalopathy, variceal bleeding, and spontaneous bacterial peritonitis (SBP). SBP is an infection of the ascitic fluid and is a serious complication of advanced CLD with ascites.

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
The liver synthesizes various proteins, including clotting factors (prothrombin). In CLD, impaired synthesis of clotting factors leads to a prolonged prothrombin time (PT) or elevated international normalized ratio (INR), indicating synthetic dysfunction and an increased risk of bleeding.
Albumin synthesis is also impaired, leading to hypoalbuminemia, but PT/INR is a more sensitive and earlier indicator of acute synthetic impairment.

সঠিক উত্তর: খ
Proliferation of abnormal white blood cells
খ
ব্যাখ্যা
Leukemia is a group of cancers affecting the blood-forming tissues, primarily the bone marrow. It is characterized by the uncontrolled proliferation of abnormal, immature white blood cells (blasts) that accumulate in the bone marrow, peripheral blood, and sometimes other organs, impairing the production of normal blood cells.

উত্তর
সঠিক উত্তর: খ
Widespread activation of coagulation and fibrinolysis
খ
ব্যাখ্যা
DIC is a complex, acquired disorder characterized by systemic activation of blood coagulation, leading to widespread fibrin formation in the microvasculature. This results in both consumptive coagulopathy (depletion of clotting factors and platelets) and secondary fibrinolysis, manifesting clinically as both thrombosis and bleeding.
