What is a nurse's first step when detecting abnormal vital signs?

The first step for a nurse when detecting abnormal vital signs is to reassess the vital signs. This step is crucial because it ensures that the initial reading was accurate and not a result of temporary factors, such as patient movement, anxiety, or equipment malfunction. Vital signs can fluctuate, and it is essential to confirm abnormalities before taking further action.

Reassessing allows the nurse to obtain a clear picture of the patient's current physiological state and helps in making informed decisions on the next steps in care, whether that may involve notifying a physician, adjusting treatment protocols, or implementing interventions based on more reliable data. This systematic approach ensures patient safety and facilitates effective treatment planning.
