Final answer:
A manager should utilize the Academy of Nutrition and Dietetics Standards of Practice and Standards of Professional Performance when assigning work to RDNs, as they provide the necessary guidelines for delivering excellence in nutrition care.
Step-by-step explanation:
When determining work assignments for RDNs (Registered Dietitian Nutritionists) providing care for patients with a variety of medical conditions, a manager should use C. Academy of Nutrition and Dietetics Standards of Practice (SOP) and Standards of Professional Performance (SOPP). These standards provide guidelines to ensure that dietitians are delivering care at a level of excellence that meets the current evidence-based practice. The SOP and SOPP cover the critical reasoning and evidence-based decision-making skills necessary to address the complex nutritional needs of patients, similar to the way a registered dietitian would manage a patient with diabetes by instructing on appropriate carbohydrate intake. In comparison, guidelines such as those from OSHA are more focused on safety and health in the workplace, while the Joint Commission sets accreditation standards for healthcare organizations. Neither are typically involved in the direct decisions regarding patient nutrition care assignments.
Answer: C. Academy of Nutrition and Dietetics SOP and SOPP
