Answer to Question 1

dorsiflexed with the toes in contact with the image receptor

Rationale: Dorsiflexion of the foot is necessary and the ball of the foot should be positioned perpendicular to the image receptor to allow the tangential beam to skim the part. The toes should be positioned closer to the image receptor to reduce magnification.

Answer to Question 2

increase technical factors

Rationale: A hemothorax is blood pooling in the pleural cavity creating an additive pathology. With additive pathologies, the technical factors may need to be increased.
