When the practical nurse (PN) atempts to assist an 18-year-old client with a mild mental disability to ambulate on the first postoperative day after an appendectomy, she becomes angry and says, "PN, 'Get out of here! I'll get up when I'm ready!" Which response is best for the PN to make?

A. "You must ambulate to avoid complications which could cause more discomfort than ambulating."

B. "I know you feel angry about the pain of ambulation, but this is a necessary part of getting well."

C. "Your healthcare provider has left specific instructions to ambulate on the first postoperative day."

D. "I will be back in 30 minutes to help you get out of bed and walk around the room today."
