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: A 54-year-old man diagnosed with diabetes mellitus type 2 came to our clinic. He reported fever of 40ºC with chills and shivering, arthromyalgia and headache, which is why he started treatment with paracetamol. The painting began 24 hours before his return to Spain. After 3 days, he presented with a generalized maculo-papular rash that progressed to the formation of more intense petechiae in the lower limbs. It provides analytics where leukopenia stands out with 3,200 / mm3 and platelets 91,000 / mm3 and mild elevation of aminotransferases. Thickness, peripheral blood smear, polymerase chain reaction (PCR) and malaria antigen are negative. What is the most likely suspected diagnosis? 
 Options:  <0> Coronavirus infection. <1> Lymphocyte choriomeningitis. <2> Dengue. <3> Chikungunya virus infection. <4> Encephalitis of Saint Louis.

Question: Plasma ICP is more suitable for rapid multielemental analysis than flame atomic absorption methods because: 
 Options:  <0> The linearity interval is not wide, which allows for very sensitive analyzes. <1> The ICP has several possibilities to introduce the sample using different types of nebulizers. <2> They use two photomultiplier tubes, one for the ultraviolet region and the other for the visible one. <3> It has load-coupled silicon solid-state detectors that allow simultaneous monitoring of a large number of lines, reducing analysis time, sample volume and improving detection limits. <4> It is not correct, because with the ICP plasma, multielemental analysis can not be done.
chemistry

Question: The method of continuous variations is used in molecular absorption spectrophotometry to: 
 Options:  <0> Determine the position of the isobestic point in a mixture of absorbent species. <1> Calculate the exact position of the absorption maximum of an absorbent complex. <2> Obtain the pH corresponding to the end point of the titration of an absorbing acid or base. <3> Calculate the stoichiometry of an absorbent complex. <4> Calculate the exact value of the dissociation constant of an absorbent acid.
