An item or task that requires immediate action is a/an _______________.

The term that refers to an item or task requiring immediate action is "priority." This concept emphasizes the importance of addressing certain tasks over others based on urgency or significance. Priorities are often determined based on deadlines, the potential impact of completing the task, and the resources available. In many work and safety contexts, identifying priorities effectively helps ensure that critical issues are addressed first, which is essential for maintaining workflow, safety, and productivity.

Objectives are broader aims that guide the direction of work but do not necessarily imply immediacy. Tasks are individual actions or pieces of work that need to be completed, but not all tasks are of equal urgency. Goals are typically long-term aspirations that may require sustained effort and planning, making them less about immediate action and more about gradual achievement. Therefore, "priority" is the most accurate term to describe something that demands prompt attention and action.
