CASE STUDY 11

CASE STUDY 11.655-year-old man with no history of illness suffered a blow to the head. He was unconscious when admitted to the hospital and remained in that state until his death 15 days later. A nasogastric tube was inserted to administer the required nutrients (protein, carbohydrates, fat, minerals, and vitamins). The total water intake was 1,500 m(L)/(d). Starting on day 5, his blood pressure gradually fell. The 24 -hour urine volumes recorded from an indwelling catheter are listed below(:)/(b)egin{tabular}[t](|l|l|)/(h)line Day After Admission & Urine Volume (m(L)/(24) h)( ()/())/(()/())hline 6 & 1,500( ()/())/(()/())hline 8 & 1,300( ()/())/(()/())hline 10 & 1,200( ()/())/(()/())hline 12 & 1,100( ()/())/(()/())hline 14 & 900( ()/())/(()/())hlin(e)/(e)nd{tabular}The patient’s hemoglobin and hematocrit were elevated.
