Which of the following serves as an outcome indicator?

Outcome indicators are measures that evaluate the results of a process, program, or intervention, usually in terms of client satisfaction or health improvement. In this context, the option regarding client satisfaction with the meals provided serves as a direct reflection of the effectiveness of the dietary services provided. This measure assesses the impact of those services from the client's perspective, indicating whether their needs and expectations are being met.

Client satisfaction is a key component in evaluating the quality of care and can lead to adjustments that enhance client experience and nutritional outcomes. This aspect not only reflects the success of the intervention but also helps in making necessary improvements to the service being provided.

The other choices reflect processes or actions rather than outcomes. Regularly recording inventories can help in management but doesn't measure how clients feel about the services. Timeliness in recording assessments and diagnoses is crucial for effective care but doesn't directly indicate how well the clients are responding to the interventions. Hence, client satisfaction is the strongest indicator of outcome in this scenario.
