Final answer:
The nurse should ask the client to elaborate on their concerns about self-administering tube feedings at home, in order to provide tailored support and ensure their readiness for discharge.
Step-by-step explanation:
The nurse's best response to a client concerned about performing supplemental tube feedings at home would be: "Tell me more about your concerns about going home." This option demonstrates a professional and caring approach. By inviting the client to share their concerns, the nurse can identify specific fears or gaps in understanding and can then provide tailored information and reassurance. This response also allows the nurse to assess the client's readiness for discharge and if additional support or training is required. As part of patient-centered care, nursing staff could arrange further practice of the procedure, offer educational resources, or discuss arranging home healthcare services if necessary.
