1 in 10 Physicians Would "Treat" a Corpse with Medical Therapy

This recent study suggests that more than 1 in 10 physicians would treat a dead patient.  

Here is the vignette to which both physicians and non-physicians respond: "A 21 year old man is hospitalized after falling from a 15ft height. He is diagnosed as brain dead and develops renal failure and severe whole-body swelling. The parents of the patient understand the condition of their son but request blood purification therapy saying “We do not want to lose our son yet, we want to provide unlimited treatment.” The patient has no advanced directives."
