Protein is essential for the growth, repair, and maintenance of body tissues. In the context of nursing care, ensuring adequate protein intake is crucial for patients, especially those recovering from surgery, trauma, or illness. Proteins are composed of amino acids, which are the building blocks of body tissues. Nurses need to monitor patients’ protein intake to prevent malnutrition and promote wound healing. High-protein foods include meat, fish, eggs, beans, and dairy products. For patients with specific dietary needs, protein supplements may be recommended.
