It is provided by trained carers rather than nurses for those needing help but not medical care. Good communication techniques include listening, making eye contact, using simple language, giving feedback without interrupting or appearing impatient. Kitchen safety means avoiding high heat with grease, using potholders for hot items, cleaning spills immediately, and being careful with knives. Signs of infection can include fever, restlessness, chills, abnormal discharge, swelling, lack of appetite, redness, pain, and changes in behavior.
