Final answer:
Scheduling routine patient care rounds is the most effective activity to determine if nursing care has been completed satisfactorily.
Step-by-step explanation:
The most effective activity to determine that nursing care has been completed satisfactorily is to schedule routine patient care rounds to evaluate the patients and the nursing care that has been completed. By conducting regular rounds, the charge nurse can directly observe the care provided by the nursing team, assess the patients' conditions, and ensure that all necessary tasks have been performed correctly. This allows for real-time evaluation and the opportunity to provide immediate feedback or interventions if needed.
