Physical Therapy Evaluation Tool (PEAT) 4 Practice Exam

Red flags for urgent medical evaluation point to potential serious illness, such as infection or cancer. Constant night pain with fever is alarming because fever suggests a systemic process and persistent night pain can indicate things like spinal infection or malignancy, which require prompt medical assessment. Unexplained weight loss further signals possible serious disease needing evaluation. When these signs appear together or with nighttime pain and fever, urgent care is indicated rather than waiting it out. In contrast, intermittent knee swelling can arise from common joint or overuse issues, and pain that improves with rest or occurs after activity typically reflects non-emergent musculoskeletal strains or overuse injuries, not an immediate threat.
