Question 2

For internal bleeding after blunt abdominal trauma, which sign is most alarming?

Accepted Answer

A rigid, board-like abdomen with increasing pain

Answer

A rigid abdomen indicates significant internal bleeding or organ injury requiring immediate emergency care.

Question 3

When is it appropriate to use a commercial tourniquet versus improvised methods for severe limb bleeding?

Accepted Answer

Commercial tourniquets are preferred when available; improvised used only if necessary

Commercial tourniquets are designed for consistent pressure and come with time-marking features; improvised versions are a last resort.
