A nurse has developed a six-month program to address the increased incidence of hospital-acquired infections among clients in a long-term care facility. The program includes three mandatory classes on proper handwashing techniques and increases the availability of hand cleansers in the facility. Which measure provides the best indication of the program's effectiveness?
- A. Survey employees to determine how often hand cleansers are used during client care.
- B. Compare the incidence of infections before and after the program's implementation.
- C. Observe a random sample of employees washing their hands three weeks after the program starts.
