What is the purpose of obtaining a baseline set of vitals on scene?

• A. To establish the patient’s physiologic state and detect changes or trends over time.
• B. To diagnose every possible condition.
• C. To determine the patient’s exact age.
• D. To delay transport.

Answer: (A)

Getting a baseline set of vitals on scene establishes how the patient is functioning at that moment and provides a reference point to detect changes as you treat and move toward transport. This initial snapshot, along with trends you monitor during care, helps you recognize early deterioration or improvement and guides decisions about interventions and how urgently to transport. Baseline vitals cover measurements like heart rate, blood pressure, respiratory rate and effort, oxygen saturation, and mental status, giving you a practical picture of the patient’s physiologic state and how it’s evolving. They are not meant to diagnose every possible condition; vitals are a monitoring tool to track status, not a comprehensive diagnostic method. They don’t reveal age, and obtaining them should support timely care and transport rather than cause delays.
