Which of the following is NOT typically included among main support service departments?

• A. Materials management
• B. Environmental services
• C. Security
• D. Human Resources

Answer: (D)

In hospital operations, main support service departments are the groups that keep daily functions running to enable patient care: they handle supplies and the environment where care happens and protect people and property. Materials management covers purchasing and distributing the supplies used in care; environmental services keeps the facility clean and safe, supporting infection prevention and patient comfort; security ensures safety and protects people and assets on site.

Human Resources, while essential to the organization, deals with staffing, training, compensation, and employee relations. Those activities, though critical, are typically categorized as administrative or personnel services rather than a primary clinical support function. So HR is not usually listed among the main support service departments.
