The nurse is teaching the patient about dietary guidelines.In discussing the four components of dietary reference intakes (DRIs) ,it is important to understand which of the following?

A) The estimated average requirement (EAR) is appropriate for 100% of the population.
B) The RDA meets the needs of the individual.
C) Adequate intake determines the nutrient requirements of the RDA.
D) The tolerable upper intake level is not a recommended level of intake.

The tolerable upper intake level is the highest level that probably poses no risk of adverse health events.It is not a recommended level of intake.The EAR is the recommended amount of a nutrient that appears sufficient to maintain a specific body function for 50% of the population according to age and gender.The RDA reflects the average needs of 98% of the population,not the exact needs of the individual.Adequate intake is the suggested intake for individuals that is based on observed or experimentally determined estimates of nutrient intakes and is used when evidence is insufficient for setting of the RDA.
