What factor represents the obligation to complete a task after it has been assigned in nursing?

The correct choice is the concept of responsibility, which in the context of nursing signifies the obligation to complete tasks and uphold the standards of care after assignments have been made. When a nurse is responsible for a task, it means that they have accepted the duty that goes along with that task, which includes its execution and the outcomes associated with it. This is crucial in healthcare, as it emphasizes the nurse's role in ensuring patient safety and quality of care.

Responsibility in nursing encompasses both the ethical and professional obligations to provide care and to follow through with the necessary actions once a task or duty has been assigned. It ensures that nurses are accountable for their actions and the care they provide.

Accountability, while related, pertains to being answerable for the outcomes of those responsibilities and is often linked to the overall oversight and evaluation of performance. Authority relates to the power or right to make decisions and direct others, which is distinct from the obligation to complete assigned tasks. Delegation involves assigning tasks to others and does not directly represent the obligation of the individual who has been assigned a duty.
