Final answer:
Apricots are a good source of dietary iron and a suitable choice among the provided options. Vitamin C aids in the absorption of iron, making it beneficial to include vitamin C-rich foods like oranges with iron-rich foods. Iron-fortified foods, such as certain bread and breakfast cereals, also contribute to iron intake.
Step-by-step explanation:
The nurse instructs the client diagnosed with iron deficiency anemia that good dietary sources of iron include red meat, legumes, and spinach, among others. When looking at the options presented, apricots contain a notable amount of iron and can thus be considered a good source, which makes them the best choice out of the four listed food items. It's important to note that vitamin C enhances the absorption of iron, so consuming foods rich in vitamin C like oranges can be helpful alongside iron-rich foods. Additionally, iron fortification of certain foods, like refined white bread, can help in increasing iron intake.
