Options: <1> Remove the entire catheter and reinsert it. <2> Extract about 10 cm the catheter and install the appropriate treatment. <3> Channel another central venous line through the jugular vein. <4> Leave it as it is because it can be used to monitor central venous pressure. <5> We can not use the catheter because it has perforated the vein and it is located in the lung.

Answer: 2

Question: Question: The alkali halides, MX:
Options: <1> They are solids that melt below 100C. <2> They form crystals of intense colors. <3> They can be obtained by reaction of the M2CO3 carbonates with the aqueous solutions of the HX hydrogen halides. <4> None of them can be found in nature. <5> They are liquid at room temperature.

Answer: 3

Question: Question: In relation to the colligative properties of a solution it can be said that:
Options: <1> They have their origin in the decrease of the chemical potential of the solvent by the fact of adding a solute. <2> The decrease in the vapor pressure of the solvent to which a non-volatile solute is added is directly proportional to the mole fraction of the solvent. <3> The addition of a solute to a solvent causes the range of temperatures in which the solution is maintained in the liquid state to be lower than that corresponding to the pure solvent. <4> The molal constant of descent of the freezing point depends on the nature of the dissolved solute. <5> Cryoscopic descent is a technique applicable to the determination of the molar mass of the solvent.
