A home health nurse provides medical care and support to patients in their homes, acting as a bridge between the patient and their healthcare team. During visits, they perform various tasks, including assessing the patient's health condition, administering medications, providing wound care, and educating patients and their families on managing illnesses or injuries. They monitor vital signs, manage pain, and assist with activities of daily living, aiming to improve the patient's quality of life and facilitate independent living whenever possible.
