Final answer:
To revise a patient's care plan during the implementation step of the nursing process, reassess the patient, validate nursing diagnoses, decide on the appropriateness of interventions, and modify the care plan as needed.
Step-by-step explanation:
During the implementation step of the nursing process, nurses carry out their care plans and reassess the patient's needs, making necessary adjustments. The correct order for reviewing and revising a patient's plan of care would be:
Reassess the patient.
Compare assessment findings to validate existing nursing diagnoses.
Decide if the nursing interventions remain appropriate.
Modify care plan as needed.
This sequence ensures that the care plan is based on the most current assessment of the patient's condition. It is a dynamic and responsive approach to patient care, reflecting the importance of continual assessment and adjustment of the care plan.
