A nurse case manager is caring for a population of clients in the community. Which of the following demonstrates the role of a liaison?

Rationale: A. A liaison negotiates with service providers to obtain accessible cost-effective care: One of the primary roles of a nurse case manager as a liaison is to connect clients with necessary healthcare services. This includes coordinating with service providers, negotiating costs, and ensuring that clients have access to appropriate, cost-effective care to meet their needs. B. A liaison promotes interprofessional communication: While promoting communication among healthcare team members is an important function of case management, it is more closely aligned with the role of a coordinator rather than the liaison function, which focuses on external connections and access. C. A liaison monitors the use of clinical practice guidelines for delivery of care: Monitoring adherence to clinical guidelines is part of quality assurance and clinical oversight, which falls under the role of a case manager or quality improvement nurse, not specifically the liaison role. D. A liaison measures the quality of services being provided: Measuring service quality is a responsibility related to quality management or evaluation within case management, not the primary function of a liaison. The liaison role emphasizes connecting clients to resources rather than evaluating service performance.
