Final answer:
The nurse is demonstrating the Planning step of the nursing process by discussing the expected outcomes of care with the client and family.
Step-by-step explanation:
The step of the nursing process being illustrated when a home health nurse reviews the nursing care with the client and the family and then mutually discusses the expected outcomes of the nursing care to be provided is Planning (Option B). During the planning phase, the nurse develops a plan that prescribes strategies and alternatives to attain expected outcomes. These strategies involve the collaboration and agreement of both the nurse and the patient, and in the case of home health nursing, often with the patient's family as well. As part of quality patient care under the direct supervision of a registered nurse, the planning step is critical to setting goals that are tailored to the patient's specific needs, which may include providing dialysis treatments, monitoring vital signs, and ensuring sterile procedures.
