Oregon Certified Nursing Assistant State Practice Exam

Who is responsible for diagnosing disease and prescribing treatment?

1. Nursing assistant (NA)

2. Resident

3. Physician (MD)

4. Dietitian (RDT)

The correct answer is: Physician (MD)

The responsibility for diagnosing diseases and prescribing treatment lies with the physician (MD). Physicians are trained medical professionals who undergo extensive education and clinical training to understand the complexities of human health, medical conditions, and the appropriate interventions required to treat those conditions. They have the authority to perform physical examinations, order diagnostic tests, interpret results, and establish treatment plans based on their findings. Nursing assistants, while vital members of the healthcare team, focus on providing personal care and support to patients under the supervision of licensed nurses and other healthcare professionals. They do not have the training or legal authority to make diagnoses or prescribe any form of treatment. Residents, on the other hand, may be patients receiving care and are not responsible for determining their own medical treatment. Dietitians specialize in nutrition and may offer dietary advice as part of a treatment plan, but they do not diagnose diseases or prescribe treatments as a physician would. Understanding the distinct roles within the healthcare team is crucial for ensuring that patients receive appropriate and effective care tailored to their needs.
