Tertiary level interventions have the purpose of assisting the patient in readapting to life with an illness. By adjusting the diet to meet dietary guidelines and also addressing adolescent emotional needs, the nurse will help the teen to eat an appropriate diet without health complications and see herself as a typical and normal teenager. Teaching about the food pyramid will not address the real issue, which is that the teen is still eating what she knows will make her ill. Administering antidiarrheal medications may help but is not a tertiary level intervention. Admonishing the teen and parents is not a tertiary level intervention, and because this approach is nontherapeutic, it may cause communication problems.
