To become a nurse, one needs compassion, kindness, and the ability to work as part of a team. Nurses treat and educate patients and their families, give medications, help doctors provide information to patients, and advise patients on managing illnesses or injuries. They work in various environments like hospitals, primary care facilities, and communities, often working day or night shifts. The education required ranges from a high school degree to a bachelor's degree from an approved nursing program along with obtaining a license.
