A nurse is caring for a client who has a new diagnosis of metastatic lung cancer. The client states, "I can't think about that until after my first grandchild is born next week." The nurse should identify the client's statement as indicating the maladaptive use of which of the following defense mechanisms?

A. Determine the client's degree of physical dependence:
This action is important but usually comes after the initial assessment and documentation. Assessing the degree of physical dependence involves evaluating the client's withdrawal symptoms, tolerance, and other physical health parameters. It helps in planning the appropriate level of care, such as detoxification if needed.

B. Discuss the treatment plan with the client:
While discussing the treatment plan is crucial, it's typically done after gathering essential information about the client's alcohol use, medical history, and current condition. The treatment plan is tailored based on the gathered data, which includes documenting the client's alcohol use.

C. Document the client's alcohol use in the medical record:
This is the first step because it provides a formal record of the client's alcohol use history, including patterns and any associated complications. Documenting this information helps in comprehensive care planning and ensures that all healthcare providers involved in the client's treatment have accurate and up-to-date information.

D. Initiate a referral for treatment for alcohol use disorder:
Referrals are essential, but they usually follow the initial assessment and documentation. The referral process involves connecting the client with appropriate resources, such as addiction specialists, counselors, or support groups, based on the documented information and the client's needs.

A. Request that the client's partner sign the consent form:
While involving the client's partner might offer emotional support and facilitate communication, legal and ethical guidelines typically require the informed consent of the individual undergoing the procedure. Having a partner sign the form without the client's explicit consent would not adhere to these standards.

B. Inform the client about the risks of refusing ECT:
Educating the client about the potential risks and benefits of ECT, as well as discussing alternative treatments, is a crucial step in the informed consent process. However, merely informing the client does not replace the need for the client to provide explicit, written consent for the procedure to be performed legally and ethically.

C. Cancel the scheduled ECT procedure:
This is the correct action. Without the client's signed consent, the procedure cannot proceed. Canceling the ECT procedure respects the client's autonomy and adheres to legal and ethical standards surrounding informed consent. The healthcare team should continue to engage with the client, addressing any concerns and questions, to obtain their informed and voluntary consent before rescheduling the procedure if the client chooses to proceed.

D. Proceed with preparation for ECT based on implied consent:
Implied consent is not sufficient for significant medical procedures such as ECT. Implied consent implies agreement based on actions or behavior rather than explicit, informed agreement. For procedures like ECT, it is essential to have documented, explicit, and voluntary consent from the client before proceeding. Relying solely on implied consent would not meet the ethical and legal requirements for informed consent.
