Pediatric Nurses care for patients ranging from infancy to late adolescence. They work closely with other healthcare professionals, such as family doctors, pediatric physicians and other nurses, to provide preventative and acute care. The main role of pediatric nurses is to administer directly procedures and medicines to children according to prescribed nursing care plans. Nurses also continually assess the patient by observing vital signs, and developing communication skills with children and family members and with medical teams. Typical duties include conducting routine developmental screenings, "well child" examinations, administration of immunizations, and the diagnosis and treatment of common childhood illnesses, such as chickenpox, ear infections and tonsillitis. Pediatric nurses also work closely with patients' families, educating them about the role of health during child development and bringing awareness to issues that are vital during childhood, such as child disease prevention, proper nutrition, and growth and development.
