[Q]: Question: If the normal reduction potential of the pair Zn2 + / Zn is -0.76 V: 
 Options:  <1> Aqueous solutions of Zn2 + at pH = 0 release oxygen. <2> Putting metallic Zn in aqueous solution at pH = 0 releases oxygen. <3> Aqueous solutions of Zn2 + at pH = 0 give off hydrogen. <4> By putting metallic Zn in aqueous solution at pH = 0, hydrogen is evolved. <5> Zn2 + dismutates in aqueous solution at pH = 0.
[A]: 4


[Q]: Question: A 70-year-old woman, worried about her risk of having a stroke, comes to our office because her mother died of this cause a year ago. He has a history of high blood pressure and type 2 diabetes mellitus, so he is being treated with glipizide, aspirin, enalapril and atorvastatin. He smokes 20 cigarettes a day and does not exercise regularly. On examination, a blood pressure of 150/80 mmHg is detected. The analytical highlights a hemoglobin A1c of 8% and an LDL cholesterol of 110 mg / dl. Which of the following is associated with a greater reduction in stroke risk? 
 Options:  <1> Achieve optimal levels of hemoglobin A1C. <2> Achieve an optimal control of blood pressure. <3> Add an antioxidant to the treatment. <4> Abandon tobacco <5> Achieve optimal levels of LDL.
[A]: 2


[Q]: Question: For bi-component drugs it is true that: 
 Options:  <1> The apparent volume of the distribution decreases with time from a maximum value to a value that becomes constant. <2> The apparent volume of distribution as a function of the area is greater than the apparent volume of distribution in the steady state of equilibrium. <3> The apparent volume of distribution is constant over time. <4> The so-called initial distribution volume is greater than the apparent volume of distribution in phase . <5> The apparent volume of distribution calculated by extrapolation is less than the apparent volume of distribution in the steady state equilibrium.
