question:
Question: A 65-year-old man, smoker and diabetic, is brought to the Emergency Department for presenting an oppressive, deep-throating sweat for about an hour. In the ECG performed, sinus rhythm was observed at 80 bpm and a complete block of the left branch. What should our attitude be? 
 Options:  <1> Perform an analytical determination of troponin and wait for its result to confirm the presence of an acute myocardial infarction. <2> Treat the patient as if it were an infarction with ST-segment elevation, proposing a reperfusion therapy as early as possible. <3> To implant a transcutaneous pacemaker before the possibility of developing a more advanced block. <4> Perform an urgent CT to rule out the presence of an acute pulmonary embolism. <5> As it could be an acute pericarditis, we will administer NSAIDs.
answer:
2


question:
Question: The reaction of Wolff-Kishner is one: 
 Options:  <1> Oxidation of carbonyls to give acids. <2> Reduction of carbonyls to alcohols. <3> Deoxygenation of carbonyls that takes place in an acid medium. <4> Deoxygenation of carbonyls that is carried out in an alkaline medium. <5> Carbonyl deoxygenation performed in neutral medium.
answer:
4


question:
Question: 30-year-old man without a history of interest. He came to the clinic because of the presence of small erythematous-violaceous lesions that appear elevated on palpation, in the pretibial region. The analytical study shows a blood count and coagulation study without alterations and in the biochemistry, creatinine and ions are also within the range of normality. The study of urinary sediment demonstrates hematuria, for which the patient had already been studied on other occasions, without obtaining a definitive diagnosis. Regarding the entity that you suspect in this case is FALSE that: 
 Options:  <1> In 20% to 50% of cases there is an elevation of the serum IgA concentration. <2> In the renal biopsy the mesangial deposits of IgA are characteristic. <3> The existence of proteinuria in the nephrotic range is frequent. <4> It is considered a benign entity since less than 1/3 of the patients progress to renal failure. <5> Skin biopsy allows the diagnosis to be established in up to half of the cases.
