Final answer:
A nurse would be most likely to use spreadsheet software rather than word-processing software to develop a budget for the nursing unit.
Step-by-step explanation:
The task that a nurse would be most likely to perform using spreadsheet software rather than word-processing software is developing a budget for the nursing unit. Spreadsheet software, such as Microsoft Excel, allows users to create complex calculations, analyze data, and create charts and graphs, which are essential for budgeting and financial planning. Nurses can use spreadsheet software to track expenses, project future costs, and create detailed financial reports for their nursing unit.
