Answer 1

climax  Ã‚· McMurphy reasserts himself against Nurse Ratched at the end of Part II by smashing the glass window in the Nurses' Station, signaling that his rebellion is no longer lighthearted or selfish but committed and violent. McMurphy takes on the responsibility for rehabilitating the other patients.

Answer 2

I would think that her weapon would be performing the labotomy on McMurphy.
