Final answer:
Failure to act as a client advocate can have serious consequences for both the client and the nurse.
Step-by-step explanation:
When a nurse fails to act as a client advocate, there can be several consequences. Firstly, there may be life-threatening complications for the client as their needs and rights are not properly addressed. Secondly, the nurse and/or healthcare facility may face legal action for negligence or malpractice. Thirdly, the nurse's license to practice nursing may be suspended or revoked, which could result in the loss of their career. Additionally, failure to act as a client advocate can lead to a loss of client autonomy and the right to make decisions.
