3. In Ischemiareperfusion syndrome: A. Occurs during the period of systemic hypoperfusion B. Acid and potassium built up during hypoperfusion in shocked patients can lead to direct myocardial depression and further hypotension C. Microvascular thrombi activated by hypoxia in shock that flushed back into the circulation is the only cause of reperfusion syndrome D. Reperfusion after correction of shock Might lead to multiple organ failure and death E. Reperfusion injury can currently only be attenuated by reducing the extent and duration of tissue hypoperfusion 4. The followings are characteristics of shock: A. With loss of around 15 per cent of the circulating volume; Blood pressure falls B. In septic distributive shock; the peripheries are cool and sweaty with prolonged capillary refill C. In severe shock; there is profound tachycardia and hypotension. Urine output falls to zero and patients are unconscious with labored respiration D. In mild shock; urine output dips below 0.5 mL/kg per hour E. In compensated shock cardiovascular state is maintained by reducing perfusion to the skin, muscle and gastrointestinal tract
