Final answer:
The nurse should include information about ergonomics in the in-service to educate staff members about designing workspaces to reduce injury risk.
Step-by-step explanation:
Ergonomics is the subject that the nurse should include when teaching the in-service about the use of ergonomics to a group of staff members. Ergonomics is the study of designing workspaces to reduce injury risk. By incorporating ergonomics into the design of workspaces, healthcare workers can prevent or reduce the risk of musculoskeletal injuries and promote overall well-being.
