Final answer:
A dietetics professional should label a specific nutrition problem during the Nutrition Diagnosis; this is a key step in the Nutrition Care Process performed by registered dietitians.
Step-by-step explanation:
Initially, a dietetics professional undertaking Nutrition Diagnosis as part of the Nutrition Care Process should identify and label a specific nutrition problem that he or she is responsible for treating independently. This involves a critical assessment of nutritional issues that can be addressed through dietary interventions. Registered dietitians, who have completed a bachelor's degree in a relevant field, a supervised internship program, and a national exam, are qualified to perform this task. They utilize their expertise in the chemistry and physiology of food to help plan nutrition programs and manage conditions such as obesity, diabetes, and heart disease.
