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.
Erythrocyte Sedimentation Rate (ESR) is also called Sed Rate or Sedimentation Rate. It is a simple test used to determine how much inflammation is in the body, but it cannot diagnose the specific condition causing the inflammation.SR tests are most often used to help diagnose rheumatoid arthritis, polymyalgia rheumatica and giant cell arteritis (GCA). Rheumatoid arthritis causes inflammation of the lining of the joints, resulting in pain, joint damage and sometimes deformity.
