Simulation is not just technology but a teaching method used to allow students to practice in a safe environment. The focus of simulation is to improve patient safety, communication, and the ability of the student to think and act as a nurse or advanced practice nurse. As use of simulation in nursing education increases, more regulations, guidelines, and standards are being developed to assist nursing programs to obtain best outcomes. This article provides readers with an overview of simulation use in undergraduate and graduate nursing education.

It was recognized more than 60 years ago that administration of carbohydrate to fasting animals causes a fall in urinary nitrogen output, whereas the giving of fat does not have a similar effect (see review of literature by Munro, 1951). In confirmation of this difference between the actions of carbohydrate and fat, the giving of glucose to fasting subjects causes a sharp and transient fall in blood amino-acid concentration, which does not occur after the administration of fat (Munro & Thomson, 1953). Thus carbohydrate has some specific action on the protein metabolism of fasting animals, but, despite attempts at elucidation, the mechanism remains obscure (Munro, 195 I).
