Final answer:
The Edmonton Symptom Assessment System does not include 'stress' as one of the nine common symptoms it measures; it includes symptoms like pain, tiredness, and well-being.
Step-by-step explanation:
The Edmonton Symptom Assessment System (ESAS) is a tool used to assess nine common symptoms experienced by patients with cancer and other serious illnesses. These symptoms are measured on a scale from 0-10, with 0 indicating that the symptom is not present and 10 indicating the worst possible severity. The nine symptoms typically included in the ESAS are pain, tiredness, nausea, depression, anxiety, drowsiness, appetite, wellbeing, and shortness of breath. Therefore, the symptom not included in the Edmonton Symptom Assessment Scale among the options provided is stress.
