Answer to Question 1

carina

Rationale: The carina is the lowest cartilaginous ring on the trachea right before the trachea bifurcates into the right and left primary bronchi.

Answer to Question 2

decrease in kVp

Rationale: Destructive pathologies will need a reduction in technical factors to avoid overpenetration since normal tissue is lessened.
