Final answer:
The nurse should recommend the client to eat leafy green vegetables to help with her heavy menstrual flow and need for extra iron.
Step-by-step explanation:
The nurse should recommend the client to eat leafy green vegetables to help with her heavy menstrual flow and need for extra iron. Leafy green vegetables are a good source of iron and also provide other vitamins like vitamin A and folic acid.
Another good source of iron that the nurse could recommend is red meat. Red meat is high in iron and can help replenish iron stores in the body.
While citrus fruits like oranges and lemons are high in vitamin C and can help with iron absorption, they are not the best food choice for increasing iron levels. Therefore, the nurse should recommend the client to focus on consuming leafy green vegetables and red meat for her iron needs.
