Answer to Question 1

2

Rationale: The developer has two primary agents: phenidone and hydroquinone. Phenidone will create the lower densities and hydroquinone will create the higher densities. Collectively they are responsible for producing densities on the image.

Answer to Question 2

directly outside the patient's room

Rationale: A portable unit that must be cleaned after completing imaging on a patient under Strict Isolation Precautions should take place directly outside the patient's room to prevent spread of transmission through return route to the radiology department.
