[{'content': 'Peripheral resistance is decreased in which type of shock -a) Hypovolemic shockb) Neurogenic shockc) Septic shockd) Cardiogenic shock \nSelect and explain. \nA. a, B. c, C. ac, D. bc', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Septic shock has already been described → in hyperdynamic stage there is vasodilation and \xa0↓ TPR.\nNeurogenic shock\n\nNeurogenic shock occurs when there is Neurological injury as occur in head trauma or high cervical cord injury or cephalad migration of spinal anaesthesia.\nInterruption of sympathetic vasomotor input occurs that causes vasodilatation, decreased heart rate and\xa0Cardiac output and shock.\n\tThen what is the difference between neurogenic shock and hyperdynamic stage of septic shock ?\nIn septic shock, there vasodilatation ( ↓\xa0TPR) due to NO with associated reflex sympathetic activity that increases heart rate and cardiac output.\nOn the other hand, in neurogenic shock there is decreased sympathetic drive that leads to decrease in all, i.e., peripheral resistance, cardiac output and heart rate.', 'role': 'assistant'}]
