A certified nurse practitioner (CNP) is a registered nurse with the training and knowledge to diagnose and treat illnesses, prescribe medications and administer physical examinations. Nurse practitioners provide comprehensive holistic care of patients by emphasizing prevention, education and wellness. Job functions include ordering diagnostic tests, prescribing physical therapy, providing health education and performing tasks such as biopsies, suturing and casting. If you're interested in this career, there are several CNP nursing degree specializations, including family practice, neonatal care, acute care and psychiatric mental health care.
