Non thrombocytopenic purpura is seen in all except:

Correct Answer: D

Rationale: The correct answer is D: SLE. Non-thrombocytopenic purpura refers to purpura without low platelet count. In SLE, thrombocytopenia is common, leading to purpura. A: Vasculitis can cause non-thrombocytopenic purpura due to vessel inflammation. B: Uraemia can lead to non-thrombocytopenic purpura due to vascular damage. C: Hereditary haemorrhagic telangiectasia presents with telangiectasias and recurrent epistaxis, not purpura.

Correct Answer: D

Rationale: The correct answer is D: hereditary spherocytosis. In this condition, there is splenomegaly due to hemolysis, leading to jaundice. The increased MCH (mean corpuscular hemoglobin) is a characteristic finding in hereditary spherocytosis. Liver cirrhosis (choice A) may cause jaundice but is not typically associated with splenomegaly and increased MCH. Thalassemia major (choice B) presents with microcytic anemia and not typically associated with increased MCH. Paroxysmal nocturnal hemoglobinuria (choice C) is known for hemolysis but does not commonly present with splenomegaly and increased MCH.

Correct Answer: B

Rationale: The correct answer is B: pancreatitis. Sickle cell anemia does not typically manifest with pancreatitis. The pathophysiology of sickle cell anemia involves sickle-shaped red blood cells leading to vaso-occlusive crises, resulting in complications such as papillary necrosis, osteomyelitis, and congestive heart failure. Pancreatitis is not a common complication of sickle cell anemia due to the absence of significant involvement of the pancreas in the disease process. Therefore, option B is the correct choice, as it does not align with the typical complications seen in sickle cell anemia.

Correct Answer: D

Rationale: Step-by-step rationale: 1. Macrocytosis refers to larger-than-normal red blood cells. 2. Systemic Lupus Erythematosus (SLE) is not typically associated with macrocytosis. 3. Anemia of myxedema, methotrexate-induced, and chronic alcoholism-induced liver disease can all lead to macrocytosis. 4. Therefore, the correct answer is D: SLE, as it is not commonly associated with macrocytosis.

Correct Answer: A

Rationale: The correct answer is A: Hypercalcemia. In multiple myeloma, bone destruction releases calcium into the bloodstream, leading to hypercalcemia. This can result in symptoms like excessive thirst, fatigue, confusion, and kidney issues. Hyperproteinemia (B) is not typically associated with multiple myeloma. Elevated serum viscosity (C) is more related to conditions like Waldenström macroglobulinemia, not multiple myeloma. Elevated RBC count (D) is not a common finding in multiple myeloma and is more suggestive of polycythemia vera.
