Final answer:
The nurse should respect the client's wishes and communicate with the daughter. No additional tests may be necessary, and treatment should focus on keeping the client comfortable.
Step-by-step explanation:
The best action for the nurse to take in this situation is to respect the client's wishes and communicate with the daughter about the decision. It is important to uphold the client's autonomy and provide support for their chosen treatment plan. The nurse can have a conversation with the daughter to explain the client's decision and address any concerns or questions she may have.
Additional tests that should be performed on the patient would depend on the specific needs and symptoms of the client. However, given the client's expressed desire to not continue further treatment, it would be essential to focus on the client's comfort and symptom management rather than conducting further testing.
The type of treatment recommended for the client would also depend on their individual circumstances and healthcare provider's assessment. However, if the client has clearly expressed their desire to not continue with further treatment, the doctor should respect their wishes and may consider options such as palliative care or hospice services to keep the client comfortable.
