Final answer:
The Registered Dietitian Nutritionist (RDN) plays a crucial role in developing an intervention for Mrs. Clarke's vitamin D deficiency by assessing her dietary intake and recommending specific foods or supplements. The RDN should consider her individual needs and health status when selecting a micronutrient supplement and provide guidance on proper dosage and potential interactions.
Step-by-step explanation:
The role of a Registered Dietitian Nutritionist (RDN) in developing an appropriate intervention for Mrs. Clarke's vitamin D deficiency is to assess her dietary intake of vitamin D and identify potential sources of deficiency. The RDN may recommend specific foods that are rich in vitamin D, such as fatty fish, fortified milk, or cereal, to increase her intake through dietary changes. Additionally, the RDN may provide guidance on lifestyle factors that can affect vitamin D levels, such as sun exposure and physical activity.
When selecting a micronutrient supplement for Mrs. Clarke, the RDN should consider her individual needs and health status. They may consider prescribing a vitamin D supplement if her deficiency is severe or if dietary changes are insufficient. The RDN should also provide guidance on proper dosage, timing of supplementation, and potential interactions with other medications or supplements that Mrs. Clarke may be taking.
