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'.

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.

Question: The Arrhenius equation: 
 Options:  <1> It relates the speed of a chemical reaction with the so-called constant velocity and with the concentrations of the reactants raised to their stoichiometric coefficients. <2> It relates the constant of speed of a chemical reaction with the energy of activation of said reaction, so that if the energy, of activation is high the reaction is fast. <3> It is only fulfilled for unimolecular reactions. <4> It relates the speed constant to the temperature through the activation energy and the pre-exponential factor. <5> It allows to obtain the activation energy of an elementary reaction by only representing the decimal logarithm of the temperature versus the inverse of the reaction time.

Question: Iron deficiency anemia is treated with oral or parenteral preparations: 
 Options:  <1> Only ferrous salts should be used orally. <2> Only ferric salts should be used orally. <3> Orally, the most appropriate form is the iron-dextran complex. <4> Orally, the treatment should last a maximum of fifteen days. <5> Only ferrous salts should be used parenterally.
