A victim of a near drowning has been admitted to the emergency department. The patient was submerged for 10 minutes and remains unconscious. What possible damage to the body has occurred as a result of the submersion?
A) Atrophy to brain cells
B) Cellular repair
C) Hypoxia to the brain
D) Necrosis to the brain
Ans: C
Feedback: The length of time different tissues can survive without oxygen varies. The brain will become hypoxic in 3 to 6 minutes. The other options are incorrect because submersion injuries do not cause atrophy to brain cells right away; submersion injuries also do not cause cellular repair or necrosis to the brain.
