(*)Degree of burn that is characterized by bone involvement - AnswerFourth
7-year-old girl is found at the bottom of a swimming pool. Initially she was in full arrest but after
5 minutes she showed sinus tachycardia but no respiratory effort. Intubation was done in the field
and cervical collar placed. After transport to the emergency department she was unresponsive
with a blood pressure of 100/60 mmHg, pulse 105, temperature 34.3C, and oxygen saturation
100%. The pupils were 3 mm and sluggishly responsive to light. There is no response to pain.

sinus tachycardia. There is no rectal tone. Which of the following should be the next step in
management?

D. Right and left decubitus chest radiographs - AnswerA. Cervical spine films and CT of the
head

most appropriate treatment?
A. IV bicarbonate

intraperitoneal bleeding?
, A. Diagnostic peritoneal lavage
B. CT of the abdomen
C. Abdominal ultrasound
D. Flat plate of the abdomen - AnswerC. Abdominal ultrasound
