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: The RISC complex (RNA-induced silencing complex) of RNA silencing based on interference RNA: 
 Options:  <1> It degrades the guide strand of the small interfering RNA molecules (siRNA). <2> It recognizes defective proteins and promotes their degradation. <3> It has a structure similar to the ribosome, formed by numerous RNAs and proteins. <4> It is formed, among others, by the Dicer protein, a type III ribonuclease. <5> It is part of both the interference mechanism of the siRNA and the microRNA.

SOLUTION: 5

PROBLEM: Question: When performing a central peripheral insertion venous catheterization procedure, the nurse must take into account that: 
 Options:  <1> The catheter is ready for use immediately after insertion, not needing further checks. <2> It is vital to perform a chest X-ray and / or an electrocardiographic record prior to its use. <3> A complete electrocardiogram should be performed in order to avoid possible complications. <4> The location of the tip of the catheter is only checked if parenteral nutrition is to be administered through it. <5> You need to check your position using a chest x-ray and another abdomen.

SOLUTION: 2

PROBLEM: Question: As to the height of the plate (H) in a column chromatographic separation it can be said that: 
 Options:  <1> It is inversely proportional to the variance (standard deviation of the band). <2> It is directly proportional to the number of theoretical plates and inversely proportional to the length of the column. <3> It is directly proportional to the variance and inversely proportional to the distance traveled by the center of the band to the detector (L). <4> It is directly proportional to the variance and distance traveled by the center of the band to the detector (L). <5> It does not depend on the variance or the distance traveled by the center of the band.
