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: On the molecular biology of cancer: 
 Options:  <0> Oncogenes are mutated derivatives of normal genes, called protooncogenes, whose function is to promote cell proliferation or survival. <1> Oncogenes are genes that synthesize proteins that inhibit cell proliferation. <2> The tumor suppressor genes synthesize proteins that inhibit cell death. <3> Protooncogenes synthesize proteins that promote cell death. <4> Apoptosis is a form of activation of proto-oncogenes.
answer:
chemistry


question:
Question: Question linked to image nº14 Suppose that the patient does not refer any family history of interest, has never taken illicit drugs or receives usual medical treatment. An analysis performed in a private mutual shows a microcytic and hypochromic anemia, a normal thyroid function, a serology for HIV negative and a determination of arsenic also negative. The chest x-ray is normal. To continue the study, numerous tests could be carried out. Which do you think could help us more at this time? 
 Options:  <0> A bone marrow aspirate. <1> A complete immunological study with ANA, ANCA and complement. <2> I would not do more tests immediately and follow the clinical evolution for a month. <3> A fibrogastroscopy. <4> A biopsy of the plantar lesion.
answer:
medicine


question:
Question: Patient of 79 years, hypertensive, hyperlipidemic, diabetic and with COPD in treatment with inhaled anticholinergics. He presents chronic atrial fibrillation on anticoagulant treatment with dicumarin. After a 3-day cough, yellow sputum and fever of 38 ° C, presented in the last 24 h progressive worsening with dyspnea of ​​effort, orthopnea and malleolar edema. The examination included a TA of 170/95 mmHg, dyspnea with a respiratory rate of 20 rpm and auscultation with bilateral wheezing and crackling in bases. Tachyarrhythmia at 110 bpm. Discrete malleolar edemas. What is the approach to follow? 
 Options:  <0> The patient probably has pneumonia and the priority is to perform a chest X-ray to confirm it. <1> It is probably an exacerbation of your COPD due to respiratory overinfection. Reinforce the basic treatment with an inhaled beta-2, corticoids and antibiotics and monitor evolution. <2> You probably have a component of left heart failure associated with a febrile respiratory infection. It would be a priority to treat it with vasodilators and diuretics in addition to the treatment that corresponds to their respiratory infection, bronchodilators, etc. <3> The patient is not classified for the severity of his COPD, which would indicate an immediate spirometry to adjust the treatment to the severity of the obstruction. It would also associate an antibiotic given the apparent picture of respiratory overinfection. <4> An echocardiogram would be the first exploration to be performed to rule out a possible component of heart failure associated with the exacerbated COPD episode presented by the patient.
