Virchow's node receives lymphatics from all except:

Correct Answer: C

Rationale: Virchow's node, also known as the left supraclavicular node, receives lymphatics primarily from the abdomen. The correct answer is C (prostate) because the prostate does not drain into Virchow's node. The stomach, breast, and testes all have lymphatic connections to Virchow's node. This is due to the anatomical location of these organs and their respective lymphatic drainage pathways. The stomach drains into the celiac lymph nodes, which then connect to Virchow's node. The breast drains into the axillary lymph nodes, which also communicate with Virchow's node. The testes drain into the para-aortic lymph nodes, which eventually lead to Virchow's node. Therefore, C is the correct answer based on the unique lymphatic drainage patterns of these organs.

Correct Answer: A

Rationale: Henoch Schonlein purpura is characterized by palpable purpura, abdominal pain, arthritis, and acute diffuse glomerulonephritis. Thrombocytopenia is not typically associated with Henoch Schonlein purpura, making choice A correct. Thrombocytopenia is more commonly seen in conditions like immune thrombocytopenic purpura. Choices B, C, and D are incorrect as palpable purpura, intussusception, and acute diffuse glomerulonephritis are commonly associated with Henoch Schonlein purpura.

Correct Answer: A

Rationale: The correct answer is A: hyperchlorhydria. Pernicious anemia is characterized by vitamin B12 deficiency due to impaired absorption, not excess stomach acid. Premature graying of hair is unrelated. Presence of anti-intrinsic factor antibody and risk of gastric polyps are associated with pernicious anemia, but not hyperchlorhydria. Therefore, choice A is the correct answer as it does not align with the typical symptoms and characteristics of pernicious anemia.

Correct Answer: D

Rationale: Plat. transfusion is not indicated in immunogenic thrombocytopenia (ITP) because it is an autoimmune disorder where the body destroys its own platelets. Transfusing platelets won't solve the underlying issue of platelet destruction. In aplastic anemia (A), platelet transfusion can help due to low platelet production. In uremia with bleeding (B) and DIC (C), platelet transfusion is necessary to manage bleeding due to decreased platelet function or consumption.

Correct Answer: D

Rationale: The correct answer is D: CML. Peripheral blood picture is most useful in CML because it typically shows increased white blood cell count with left shift, basophilia, and presence of the Philadelphia chromosome. In contrast, A (NHL) primarily involves lymph nodes, B (multiple myeloma) shows monoclonal protein in serum/bone marrow, and C (myelodysplastic syndrome) presents with cytopenias and dysplastic changes in blood cells. Therefore, based on the specific findings seen in CML on peripheral blood, it is the most appropriate choice.
