A nurse is reviewing the plan of care for a group of clients. The nurse should identify that informed consent is required for which of the following procedures?

Informed consent is a legal and ethical requirement for certain medical procedures. It involves providing the client with clear and comprehensive information about the procedure, including its risks, benefits, alternatives, and expected outcomes. The client must understand the information provided and voluntarily give their consent before the procedure can be performed. Placement of a central venous catheter is an invasive procedure that carries risks and potential complications, making it necessary to obtain informed consent from the client. Wound irrigation with an antibiotic solution is a standard nursing intervention for wound care and does not usually involve invasive procedures. Informed consent is not typically required for this procedure. The administration of an iron injection using the Z-track technique is a standard nursing procedure. While it involves an injection, it is not typically considered an invasive procedure that would require informed consent. Insertion of a nasogastric tube is a common procedure that involves passing a tube through the nose and into the stomach for various purposes, such as feeding, decompression, or medication administration. While it is an invasive procedure, it is often performed in emergency or critical care situations where the client's immediate well-being takes precedence. Informed consent may not be feasible or necessary in these situations, depending on the context and urgency.
