[{'content': 'A 40 year old female patient complains of excessive bleeding and drowsiness. Patient gives a history of road traffic accident 5 hours ago and had a lacerated wound on lower back region. General physical examination reveals-\nBlood pressure-80/60mmHg.\nJuglar venous pressure- low.\nPulsus paradoxus- present.\nCardiac output- Increased.\nThe patient is in which type of shock? \nSelect and explain. \nA. Neurogenic, B. Obstructive, C. Distributive, D. Hypovolemic', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Includes anaphylactic shock, septic shock and spinal cord injury (neurogenic shock).\nInadequate organ perfusion is associated with vascular dilatation and hypotension, low systemic vascular resistance, inadequate afterload and a resulting abnormally high cardiac output.\nIn anaphylaxis, vasodilatation is due to excess histamine release.\nNeurogenic shock is caused by traumatic or pharmacological blockage of the sympathetic nervous system, producing dilatation of resistance arterioles and capacitance veins, leading to relative hypovolemia and hypotension.\n\nIn neurogenic shock, because of loss of vascular tone, JVP will fall.', 'role': 'assistant'}]
