+j +j +j +j +j +j +j +j +j +j +j +j
rhospital admission. Pulse pressure is wide. The most likely explanation for this finding is
+j +j +j +j +j +j +j +j +j +j +j +j +j +j
dehydration.
fat embolism syndrome.

increases tissue oxygen consumption and cold diuresis. - ANSWER-
+j +j +j +j +j +j +j +j
causes platelet dysfunction andclotting system failure.
