Common questions
Where is medical nutrition therapy on the RD exam outline?
On the 2022-2026 outline (exams through December 31, 2026) it is in Domain II, Nutrition Care for Individuals and Groups (topics C and D). On the 2027-2031 outline (exams from January 1, 2027) it is in Domain III, Human Nutrition and Medical Nutrition Therapy (topics D and E). CDR publishes percentages for domains, not for individual topics.
Which MNT topics come up most?
CDR does not publish counts per disease. Its outlines list a long range of conditions, from critical care and eating disorders to renal, hepatic and GI disease, plus feeding methods and enteral and parenteral nutrition, so study broadly.
