Which Exercise Plan or Activity Does the Nurse Teach the Client

Which exercise plan or activity does the nurse teach the client for the first postoperative day after a modified radical mastectomy?

A) "Perform no movement or exercise today. Keep the arm supported and the elbow flexed, and as close to your body as possible."
B) "Without moving your shoulder, straighten your elbow three times hourly and squeeze a rubber ball with your fingers."
C) "Face the wall and extend your arm straight out to the wall. Walk your fingers as far above your head as your arm will reach, and then walk them back down."
D) "Hold your operative arm straight out from the shoulder to the side. Use your nonoperative arm to pull the operative arm completely straight above your head."
