The Certified Registered Nurse Infusion (CRNI) is a specialty nursing credential intended for registered nurses whose practice centers on infusion therapy - the delivery of fluids, medications, blood components, and parenteral nutrition through peripheral and central vascular access devices. Nurses typically seek it after accumulating bedside infusion experience, and it is often used to demonstrate specialty competence to employers, patients, and credentialing committees. The CRNI case studies are 5 cases and about 3,811 words.
