instruction:
In this task, you are given a question and answer options for that question. Using this information, you have to classify each text into different topics: medicine, nursery, psychology, chemistry, pharmacology, biology.
question:
Question: A 72-year-old man with a pathological fracture in the left femur goes to the Emergency Department. After the surgical intervention, the diagnostic study was performed to find out the underlying pathology with the following findings: hemoglobin 9.5 g / dl, total protein 11 g / dl, (VN: 6-8 g / dl), serum albumin 2 g / dl, (VN 3.5-5.0 g / dl), beta 2 microglobulin 6 mg / l (VN 1.1-2.4 mg / l), serum creatinine 1.8 mg / dl (VN: 0 , 1-1.4 mg / dl). Indicate what would be the diagnostic tests necessary to confirm the most probable diagnosis: 
 Options:  <0> Radiological bone series and bone marrow aspiration. <1> Serum and urinary electrophoresis and renal function tests. <2> Bone marrow aspirate and serum calcium concentration. <3> Bone marrow aspiration and serum and urinary electrophoresis. <4> Biopsy of the pathological fracture and radiological bone series.
answer:
medicine


question:
Question: Jaundice (yellowing of the skin and mucous membranes due to increased levels of bilirubin) may be of cholestatic origin (pathway obstruction) or hepatocellular damage. Indicate the correct answer: 
 Options:  <0> In cholestatic jaundice we observed: persistent alanine aminotransferase (ALT) increase without elevation of gamma glutamyltransferase (GGT). <1> In hepatocellular jaundice there is a slight increase in GGT (<5 times the upper limit of reference) and a large increase in ALT (> 10 times the upper limit of reference). <2> In cholestatic jaundice, a decrease in direct bilirubin and prothrombin time is observed. <3> In hepatocellular jaundice, a decrease in alkaline phosphatase and activated partial thromboplastin time is observed. <4> In both jaundices we can observe a clear decrease in aspartate aminotransferase (AST).
answer:
pharmacology


question:
Question: A 69-year-old woman consulted for hemoptotic expectoration. In the two previous months she had low-grade fever, asthenia, anorexia and unquantified weight loss. In the cytological analysis of sputum, hemosiderophages were observed and in the chest radiograph bilateral alveolar infiltrates were observed. Analytically it stood out: Hb 8.2gr / dL, PO2: 58mmHg, creatinine: 5mg / dL, urine: proteinuria +++ microhematuria, cylinders, hematics. ANCAp (antibodies against the cytoplasm of perinuclear neutrophils): positive: anti-glomerular basement membrane antibodies: negative. Antinuclear antibodies: negative. The most likely diagnosis would be: 
 Options:  <0> Idiopathic pulmonary hemosiderosis. <1> Goodpasture syndrome. <2> Systemic lupus erythematosus with severe renal involvement. <3> Classical polyarteritis nodosa. <4> Microscopic polyarteritis.
