For each of the types of shock listed on the left select the most appropriate cause from the list on the right

The answer is E, A, B. The commonest cause of cardiogenic shock is myocardial infarction; but rupture of a heart valve, cardiac tamponade or arrhythmia can cause it.

Hypovolaemic shock usually results from trauma - severe haemorrhage, or burns being the usual cause. In extensive burns there is considerable exudation of plasma resulting in hypovolaemia.

Septic shock occurs in patients with septicaemia or extensive localized infections, i.e., peritonitis; it may complicate gastrointestinal, urogenital or biliary surgery and can occur in immunosuppressed patients. The shock of pancreatitis (D) is probably chemical in nature, while that of incompatible blood transfusion (C) is the result of an immunologically mediated reaction.
