Her daughter Marie is staying with her during the hospitalization because Mrs. Watson is a widow. Mrs. Watson has not had surgery before, so she is not sure what to expect. She is upset about the diagnosis of cancer. Lana Bridges is a student nurse assigned to care for Mrs. Watson. She is in her last clinical rotation and will be administering all medications with her instructor's supervision.

C. "That is a valid worry. I wouldn't want to become addicted."
D. "My cousin was addicted to pain killers when he had cancer."
