Final answer:
The public health nurse should educate the parents on dietary sources of iron, the importance of iron supplementation, and enhancing iron absorption.
Step-by-step explanation:
The public health nurse should include the following education in the client's plan of care:
Dietary sources of iron: The nurse should advise the parents to include foods rich in iron in their child's diet. Good sources of iron include red meat, shellfish, seeds, nuts, legumes, and iron-fortified breakfast cereals.
Importance of iron supplementation: The nurse should explain the need for iron supplementation in the form of ferrous sulphate tablets for anemic children and discuss the appropriate dosage for different age groups.
Enhancing iron absorption: The nurse should emphasize the importance of consuming vitamin C along with iron-containing foods, as this can help increase the body's absorption of iron.
