A nurse practitioner is a registered nurse who has gone through additional training to provide more advanced medical and diagnostic care to patients with all different kinds of illnesses. These medical professionals generally hold at least a master’s degree, so they have a comprehensive basis of medical knowledge to help patients suffering from chronic and acute conditions. They may work in hospitals, intensive care units, hospice centers, and even doctor’s offices, depending on their specialty.

Psychiatrists are doctors who specialize in treating mental, addictive, and emotional disorders. They order diagnostic tests, prescribe medications, and use psychotherapy to help patients and their family members deal with these disorders and diseases. They often work with other doctors and specialists to help come up with the best treatment option for their patients.
