Clinical meaning Acute deterioration (new confusion, hypoxia, chest pain, hemorrhage, sepsis cues) requires immediate nursing actions you are authorized to take plus timely notification of the RN/NP/physician. Expect multi-client stems and therapeutic communication. Traps mirror US items: routine tasks before unstable vitals, or acting outside scope (prescribing, unsupervised major titration).
