All plants are producers, or autotrophs, which means they create their energy (or food) through a process called photosynthesis. In this lesson, we characterize producers by 3 main traits: producers make their own food; producers cannot physically move; and producers provide food and shelter for animals.
The Emergency Severity Index (ESI) is a five-level tool for use in emergency department (ED) triage. Experienced ED nurses use the ESI to rate patient acuity, from level 1 (most urgent) to level 5 (least resource intensive). The ESI is unique among triage tools, by including both acuity and resource needs in the system of categorizing ED patients.
ESI is done in a hospital or outpatient clinic. The procedure is done in the following way: 1  You change into a gown.  You then lie face down on an x-ray table with a pillow under your stomach. If this position causes pain, you either sit up or lie on your side in a curled position.
