Informed Consent (House)

"Informed Consent" is the third episode of the third season of House and the forty-ninth episode overall.

House's ketamine treatment has worn off and he is back to using his cane; but he does not want to talk about it, despite everyone's concerns. House has to diagnose Dr. Ezra Powell (played by Joel Grey), a 71-year-old renowned pioneer in the field of medical research who collapsed while studying cancer in lab rats. House puts Powell through diagnostic rigors, but the team is unable to come up with a conclusive diagnosis, and Powell's health continues to deteriorate. Becoming increasingly debilitated, Powell ultimately demands that the team stop the litany of medical tests and euthanize him. House strikes a deal with him and asks for one day to do tests on him.

The moral dilemma of whether to assist in his suicide and abide by Powell's wishes, or to ignore what their patient wants drives the team in very different directions. The team members have divergent opinions on the morality of helping Powell die. Cameron despises the idea of ignoring Powell's wishes and continuing the tests House orders, yet cannot bring herself to assist Powell in his suicide. Her inability to make up her mind is both central to the plot and to her character: throughout the episode the members of the team criticize her for her indecisiveness. Both Foreman and Cameron are opposed to watching House put Powell to sleep, but Chase seems to have little problem. Wilson says that House has done it before "plenty of times" and House insists that it was only "to patients that [he] knew were terminal."

When House fails to diagnose Powell in one day, he visits him in his room to give him the lethal morphine dose. Foreman tries to stop him, but House persists and threatens him with "What's going to happen here, is that someone is going to get a buttload of morphine. I'm not exactly sure who at this point." Foreman and Cameron leave in shock and disgust, but Chase stays to assist. But instead of killing him, House puts Powell in a coma, so that he can do his diagnosis in peace. However, during a lung biopsy, Powell's lung gives out and House is forced to intervene by which he notices that Powell has lost reflex capabilities in his right arm. In order to proceed with additional diagnostic procedures, House wakes Powell from his coma and finds that Powell has also lost sensation in his abdomen and right leg.
