Final answer:
The nurse should include the client in the development of his or her care plan for pneumonia, focusing on patient-centered care which enhances adherence and involvement.
Step-by-step explanation:
When developing the plan of care for a client with pneumonia, the nurse should include the client in the development process.
Involving the client ensures that the plan of care is centered around their individual needs, preferences, and values. It also promotes client engagement, improving adherence to the treatment plan and fostering a sense of ownership over their own health care. Other interdisciplinary team members, such as dieticians, respiratory therapists, and physicians, may also be involved according to the client's specific needs, but it's the client who is the central figure in their care planning.
