Final answer:
As an educator, a nurse provides teaching to the patient's family on medical procedures, ensures educational materials are accessible, and assesses and guides patients' nutritional needs.
Step-by-step explanation:
The role of a nurse as an educator is clearly demonstrated through various actions. Firstly, teaching the patient's family how to perform sterile dressing changes provides them with critical knowledge and skills for managing the patient's care. Additionally, providing written teaching materials in the patient's preferred language ensures that the information is accessible, thereby enhancing their understanding and engagement with their health management.
Lastly, assessing for adequate protein intake demonstrates the nurse's role in educating the patient about nutritional needs, particularly when dietary restrictions or preferences, such as vegetarianism, are present.
