A 50-year-old firefighter emerges from a burning house with third-degree burns over 70% of his body. The patient expires 24 hours later. Which of the following was the most likely cause of death?
|A.||Congestive heart failure|
Disseminated intravascular coagulation
Pulmonary saddle embolism
Correct answer : c Hypovolemic shock
Hypovolemic shock may be caused by hemorrhage, fluid loss from severe burns,diarrhea, excessive urine formation, perspiration, or trauma.

Persons with third-degree burns weep large amounts of plasma.
The other choices are unlikely causes of death in an acute burn victim.
