A nurse is preparing to witness a client's signature on a consent form for a colon resection. The nurse should recognize that which of the following information should be provided to the client by the provider before signing the form? (Select all that apply.)

Rationale: A. Possible alternative treatments: The provider is responsible for informing the client about all viable treatment options. This allows the client to make an informed decision by weighing the benefits and risks of each option. B. Expected outcome of the procedure: Clients must understand the intended benefits and goals of the procedure. This helps them form realistic expectations and evaluate whether the procedure aligns with their preferences and values. C. Explanation of the procedure: A clear and complete description of the procedure must be provided, including what it involves and how it will be performed. This is essential for valid informed consent. D. Cost of the procedure: While important for financial planning, cost information is typically handled by billing or administrative staff, not required for medical informed consent by the provider. E. Potential complications: Clients need to be informed about potential risks and complications to fully understand the implications of undergoing the procedure. This disclosure is legally and ethically required for consent.
