A nurse is providing nutritional teaching to the mother of a preschooler and is recommending food options to provide 1 oz of grains. Which of the following foods should the nurse recommend?

The correct answer is C: 1 cup ready-to-eat cereal flakes. One cup of ready-to-eat cereal typically provides around 1 oz of grains, making it the most suitable option for the preschooler. Choice A (1 cup cooked rice) usually provides more than 1 oz of grains, exceeding the recommendation. Choice B (1/2 slice of white bread) is less than 1 oz of grains. Choice D (1/2 white flour tortilla) is also less than 1 oz of grains. Therefore, choice C is the best option to meet the recommended 1 oz of grains for the preschooler.
