A nurse is teaching an adolescent about increasing calcium intake. Which of the following foods should the nurse recommend?

Choice A reason: Eggs contain protein and some vitamins but are not a significant source of calcium. They do not contribute meaningfully to calcium intake. Choice B reason: Chicken is a good source of protein but contains negligible calcium. It is not recommended for increasing calcium intake. Choice C reason: Spinach contains calcium and is a plant-based source of this mineral. Although it also contains oxalates that reduce calcium absorption, it is still considered a calcium-rich food and appropriate for dietary teaching. Choice D reason: Raisins provide iron and fiber but are not a significant source of calcium. They do not contribute to bone health in the same way calcium-rich foods do.
