Input: Consider Input: Question: A 73-year-old woman is brought to the emergency room accompanied by the family due to a picture of chills and a productive cough of purulent mucus that lasted about 2 days; they also report a tendency to drowsiness with a decrease in oral intake to both liquids and solids. As background we report that the patient is diagnosed with hypertension, DM type 2 and incipient dementia. The physical examination highlights a thin patient, with discrete mucous dryness, sleepy but reactive to verbal commands. Meningism or motor or sensory focality is not objective. Temperature 35.9ºC. Heart rate 118 bpm, BP 84/50 mmHg, respiratory rate 22 rpm. O2 Saturation 93%. Cardiac tachyarrhythmic auscultation without murmurs. Respiratory auscultation with crackles in the right base. Point out the TRUE answer: 
 Options:  <1> Among the measures to be taken when sepsis is suspected, antibiotic therapy is administered in the 1st hour of arrival, although this attitude has not been correlated with a decrease in mortality. <2> The early administration of IV fluids is essential to maintain adequate tissue perfusion, the goal being to maintain an average blood pressure> 65 mmHg. <3> Among the complementary tests that are received we observed a lactate> 5.6 mmol / L; it must be taken into account but as long as hemodynamic stability is maintained we should not worry. <4> In fact, the diagnosis of sepsis is not correct since the absence of fever rules out it. <5> The patient presents hypotension despite intensive administration of intravenous fluid therapy; It is time to administer vasoactive drugs, with isoproterenol being the choice.
