Final answer:
The nurse should begin to include the patient's wife in the teaching around the management of the disease when the patient becomes unable to manage his symptoms independently.
Step-by-step explanation:
The nurse should begin to include the patient's wife in the teaching around the management of the disease when the patient becomes unable to manage his symptoms independently. Including the patient's wife earlier may be beneficial, but it may also overwhelm the patient or impede their adjustment to the treatment regimen. Waiting until the patient requests assistance from his spouse and family might delay necessary education. Therefore, the most appropriate time is when the patient becomes unable to manage his symptoms independently.
