A physician tells the nurse that he informed the client about his lung biopsy scheduled for the following day and that the client just needs to sign the form for the procedure to move forward. The doctor asks the nurse to take the form to the client for his signature. When the nurse asks the client if he understands what the lung biopsy will involve, the client states that after the biopsy the spot on his lung will be gone. Should the nurse allow the client to sign the form at this time or take other action?
