Final answer:
The correct answer is A: Practice. Professional Practice standards provide guidelines for dietetics professionals to ensure competent behavior in their roles.
Step-by-step explanation:
The standards of professional Practice for dietetics professionals describe in general terms a competent level of behavior in the professional role. These standards provide a framework for evaluating performance and guide the development of professional dietitians. Registered dietitians are charged with planning nutrition programs for individuals in a variety of settings, such as health care facilities, nursing homes, schools, and private practices. By undergoing a supervised internship program and passing a national exam, dietitians certify their proficiency in the field. The extensive coursework in nutrition, chemistry, biochemistry, biology, microbiology, and human physiology is essential to understand the complex chemistry and physiological impact of food nutrients like proteins, carbohydrates, and fats on the human body.
