The term that describes one's ability to remain determined despite setbacks is perseverance. Perseverance is characterized by the continued effort to achieve a goal or overcome obstacles, regardless of the difficulties encountered along the way. It reflects resilience and a commitment to persist, even when faced with challenges or failures. This quality is crucial in various fields, including healthcare, where professionals often encounter unexpected situations and demands that require sustained effort and dedication.

The other options do not capture this same meaning. Complacency suggests a sense of satisfaction with the current situation, preventing further effort or progress. Patience refers to the ability to wait calmly in the face of frustration or adversity, but does not necessarily imply active determination towards a goal. Indifference denotes a lack of interest or concern, which is the opposite of the drive needed to persist through challenges. Thus, perseverance is the most accurate term to describe the concept of determination despite setbacks.
