TASK DEFINITION: In this task, you are given a multiple-choice question about healthcare. Answer the question based on your information and classify your answers into '1', '2', '3', and '4'.
PROBLEM: Question: A basic component of spectrophotometers is the monochromator. Its function is: 
 Options:  <1> Connect the different wavelengths from the source to achieve greater light power. <2> Transform the optical signal measured by the detector into an electrical signal. <3> Disperse the light separating the wavelengths that compose it and select a narrow band. <4> Amplify the analytical signal by improving the signal-to-noise ratio. <5> Decrease the power of the light beam to eliminate the background noise of the spectrophotometer.

SOLUTION: 3

PROBLEM: Question: Point out the correct answer in relation to the monitoring of plasma drug concentrations: 
 Options:  <1> Allergy reactions are related to the dose administered. <2> The extraction of the blood sample must be done once the balance of drug distribution in the organism has been reached. <3> The information provided by the analytical determination of plasma concentration is sufficient to perform the dosage individualization. <4> Only the immunoassay methods are valid for carrying out the analytical determination of the blood samples. <5> It must be done for all drugs that are administered intravenously.

SOLUTION: 2

PROBLEM: Question: In a flight time analyzer in mass spectrometry: 
 Options:  <1> Ions with low m / z or lighter values ​​arrive more quickly at the detector. <2> Ions with high m / z or heavier values ​​arrive more quickly at the detector. <3> The ions do not reach the detector. <4> Ions with odd m / z ratio arrive more quickly at the detector. <5> The analysis time that is usually required is seconds.
