The project manager should also update the risk register and other project documents accordingly. The other options are not the first steps to take, as they do not address the root causes of the risks, and may not be feasible or effective in the given situation. References: PMBOK Guide, 6th edition, section 11.4; PMP Practice Exam, question 94.
