Thrombocytosis occurs in all the following, except:

Correct Answer: C

Rationale: Thrombocytosis (platelets >450,000/μL) occurs in malignancy (A cytokines), myelofibrosis (B marrow dysfunction), splenectomy (D no clearance), and chronic granulomatous disease (E inflammation), but not acute myelocytic leukemia (C) thrombocytopenia dominates from marrow suppression. AML's blast crisis consumes platelets, key in nursing for transfusion readiness, contrasting reactive thrombocytosis.

Correct Answer: D

Rationale: Cholelithiasis gallstones stems from hemolytic anemia (D), where excess bilirubin from RBC breakdown (e.g., sickle cell, Hb 8 g/dL) forms pigment stones. Malignancy (A) or cirrhosis (C) may obstruct, not form stones. High fat diet (B) risks cholesterol stones, less specific here. CHF causes congestion, not lithiasis. Hemolysis's bilirubin overload is key, guiding nursing for ultrasound and monitoring jaundice in anemia patients.

Correct Answer: B

Rationale: Chronic lymphocytic leukemia (CLL) lymph nodes show early enlargement (A), discrete (C), diffuse involvement (D), and mobility , but not tender/painful (B) painless growth (e.g., >1 cm) reflects slow B-cell accumulation. Tenderness fits infection or Hodgkin's. CLL's indolent lymphadenopathy is key, guiding nursing for staging and infection watch.

Correct Answer: D

Rationale: Hemolytic anemia RBC destruction occurs in G-6-PD (A drug-induced), thalassemia (B ineffective erythropoiesis), spherocytosis (C spleen lysis), HbC (D mild hemolysis) but not iron deficiency , where low iron reduces RBC production (e.g., Hb <10 g/dL), not lysis. Iron's non-hemolytic nature is key, guiding nursing for iron, not hemolysis workup.

Correct Answer: A

Rationale: Anemia of infection/rheumatoid arthritis chronic disease shows low plasma iron, low TIBC, high stores, low sideroblasts (A), from inflammation (e.g., IL-6) sequestering iron. Erythropoietin (B) fits renal. Normocytic (C) is pattern, not cause. Blood loss (D) is other anemias. Iron block is key, guiding nursing for inflammation control.
