Which of the following roles primarily assesses the overall needs of clients?

The role that primarily assesses the overall needs of clients is the case manager. Case managers are responsible for evaluating a client's situation, which includes understanding their medical, psychological, and social needs. They work to coordinate care, advocate for the client, and ensure that all aspects of their well-being are addressed. This involves not only assessing medical needs but also considering factors such as living conditions, support systems, and resources available to the client.

In contrast, a nurse practitioner focuses on diagnosing and treating medical conditions, often with an emphasis on patient care within a specific medical framework. A health care provider can refer to a wide range of medical professionals who deliver care but may not be directly involved in the holistic assessment of a client's situation like a case manager is. Licensed practical nurses often provide direct patient care, assisting in everyday tasks and medical needs, but they typically do not take on the broader role of assessing all factors influencing a client's life and care needs like case managers do.
