TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: chemistry

PROBLEM: Question: Epidemiology allows early detection of changes in the incidence of a certain disease in the population. For this, the most correct thing is to use: 
 Options:  <0> The etiological investigation. <1> The description of the natural history of the disease. <2> Epidemiological surveillance. <3> The evaluation of the functioning of the services. <4> None of the previous answers is correct.

SOLUTION: nursery

PROBLEM: Question: In the systematic examination of a pregnant woman at term (37 weeks of gestation), beta-hemolytic colonies are isolated from a vaginal smear, which are identified as Streptococcus agalactiae. What assessment would you make of this finding and what would be the most advisable therapeutic attitude to follow? ? 
 Options:  <0> It does not matter because it is part of the commensal microbiota of the vagina. <1> Birth by caesarean section is recommended. <2> The search for Streptococcus agalactiae in pregnant women is not indicated. <3> Immediate antibiotic treatment to the newborn. <4> Administer intravenous antibiotic prophylaxis during delivery to the pregnant woman.
