Which of the following is the most common cause of a transudative pleural effusion?
  1. Congestive heart failure
  2. Pneumonia
  3. Tuberculosis
  4. Lung carcinoma
ব্যাখ্যা
Explanation :
Transudative pleural effusions are caused by systemic factors such as increased hydrostatic pressure or decreased oncotic pressure.
Congestive heart failure is the most common cause, leading to fluid leakage into the pleural space.
In contrast, pneumonia, TB, PE, and cancer usually cause exudative effusions due to local inflammation or capillary permeability.

In the pathophysiology of Rheumatoid Arthritis, which immune cell type is primarily responsible for initiating the autoimmune cascade?
  1. B lymohocyte
  2. CD8+ T cell
  3. CD4+ T cell
  4. Dendritic cell
ব্যাখ্যা
Explanation :
CD4+ T helper cells play a central role in the initiation of RA.
They become activated in response to autoantigens presented by dendritic cells, leading to the release of cytokines (like IL-17, IFN-γ, and TNF-alpha) that promote inflammation.
These T cells also help activate B cells, which produce autoantibodies such as rheumatoid factor (RF) and anti-CCP antibodies.
Although B cells and dendritic cells are involved, CD4+ T cells are the primary initiators.
.
Which of the following laboratory findings is most consistent with primary hyperthyroidism?
  1. High TSH, high free T4
  2. Low TSH, high free T4
  3. High TSH, low free T4
  4. Low TSH, low free T4
ব্যাখ্যা
Explanation :
In primary hyperthyroidism, the thyroid gland overproduces hormones, which suppresses TSH via negative feedback.
So  low TSH and high free T4 (and often high T3).
This confirms thyrotoxicosis of thyroid origin.

Which of the following findings on a peripheral blood film is most characteristic of iron deficiency anemia?
  1. Macrocytic, normochromic red blood cells
  2. Target cells and Howell-Jolly bodies
  3. Microcytic, hypochromic red blood cells with anisopoikilocytosis
  4. Hypersegmented neutrophils and oval macrocytes
ব্যাখ্যা
Explanation :
In iron deficiency anemia, the red blood cells are smaller than normal (microcytic) and have less hemoglobin (hypochromic), giving them a pale appearance.
There is also anisopoikilocytosis, which means variation in cell size (anisocytosis) and shape (poikilocytosis).
This is the classic appearance in iron deficiency and helps distinguish it from other causes of anemia.
Hypersegmented neutrophils and macrocytes point to megaloblastic anemia, not iron deficiency.
