The nurse implements a primary prevention program for sexually transmitted diseases in a nurse-managed health center. Which outcome Indicates that the program was effective?

A) Incorrect - Developing and implementing new screening protocols does not directly indicate the effectiveness of a primary prevention program. It might indicate improved detection, but not necessarily prevention. B) Incorrect - This outcome relates to secondary prevention (rehabilitation after disease complications) rather than primary prevention. C) Correct- An improvement in average client scores on risk factor knowledge tests suggests that the primary prevention program has successfully educated clients about behaviors and practices that can help prevent sexually transmitted diseases. This improvement indicates that clients have a better understanding of the risks and protective measures, which is a key indicator of program effectiveness. D) Incorrect - Diagnosing clients early in their disease process is an outcome of early detection (secondary prevention), not primary prevention.
