Which management theory supports a nurse's promotion due to additional training linked to reduced patient complications?

The management theory that best supports a nurse's promotion due to additional training linked to reduced patient complications is Vroom's expectancy theory. This theory posits that individuals are motivated to act in a specific manner based on the expected outcome of that action. In the context of a nurse's promotion, the theory emphasizes the connection between effort, performance, and rewards.

When a nurse undergoes additional training, it enhances their competencies, leading to improved performance and ultimately reducing patient complications. This successful outcome aligns with the core premise of Vroom's expectancy theory, where the nurse's effort (pursuing additional training) results in a higher level of performance (better patient care) that is recognized through a promotion (a desirable reward). The positive cycle of effort leading to performance and ultimately to reward is essential in motivating employees in healthcare settings.

Additionally, this theory underscores the importance of the individual's belief in their ability to achieve the desired performance. If the nurse believes that their additional training will have a significant impact on patient outcomes, it can further enhance their motivation to pursue such training and, consequently, their chances for promotion based on those improved results.
