Answer to Question 1

good communication with the patient

Rationale: Good communication is the initial and best effort taken with a patient to decrease the chance of patient motion during an exposure.

Answer to Question 2

all of these answers apply

Rationale: The final process of reading the CR imaging plate includes exposing the IP to a bank of lamps to fully erase the image. Weak or nonfunctioning lamps may not be able to fully erase the plate, even though the system increases the erasure time.
