A Physician Assistant (PA) is a healthcare professional who works closely with doctors to provide patient care. PAs can perform many tasks, such as taking medical histories, conducting physical exams, and diagnosing illnesses. They are trained to treat patients and can prescribe medications, making them an essential part of the healthcare team. To become a PA, individuals typically complete a master's degree from an accredited program and pass a national certification exam. PAs work in various settings, including hospitals, clinics, and private practices, helping to improve access to healthcare and ensuring patients receive timely and effective treatment.
