ANSWERS AND EXPLANATIONS




A) The probability of survival depends on the patient's level of consciousness and elapsed time since the hemorrhage

This answer is incorrect.


Overall, about 65% of patients die after having an acute subarachnoid bleed. About 20% of patients die before reaching the hospital; around 25% of patients die subsequently because of the initial hemorrhage and its complications, and a further 20% die of re-bleeding if the aneurysm was not surgically treated. Of survivors, about 50% will be left with permanent brain damage and neurological disability.   (See References)
