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.
Definition and Classification. Surgical site infection (SSI) is a difficult term to define accurately because it has a wide spectrum of possible clinical features. The Centers for Disease Control and Prevention (CDC) has defined SSI to standardize data collection for the National Nosocomial Infections Surveillance (NNIS) program. [8, 16] SSIs are classified into incisional SSIs, which can be superficial or deep, and organ/space SSIs, which affect the rest of the body other than the body wall layers (see the image below).
