Infusion therapy involves the administration of drugs, fluids and blood to patients through injections, usually intravenously (which is known as intravenous therapy), although the term extends to intramuscular injections and epidural routes as well. The major professional organization for infusion nursing is the Infusion Nurses Society (INS). Registered nurses can earn the Certified Registered Nurse Infusion (CRNI) credential through the Infusion Nurses Certification Corporation (INCC); this certification program is accredited by both the National Commission for Certifying Agencies (NCCA) and the American Board of Specialty Nursing Certification (ABSNC). The U.S. Bureau of Labor Statistics predicts excellent, overall job growth for registered nurses. The median registered nurse salary is $62,450.
