When should you start the process of forming a general impression about a patient?

The correct timing for forming a general impression of a patient is while you and your partner are approaching them. This is an essential part of the assessment process, as it allows responders to begin gathering information about the patient’s condition even before direct interaction occurs. Observational cues, such as the patient’s posture, the presence of distress, or environmental factors, play a crucial role in the initial assessment phase.

Starting to form a general impression during the approach helps emergency responders prioritize care based on the severity of the patient's condition. It also prepares the caregiver to make informed decisions and alert additional medical personnel as necessary.

The other options do not leverage the early observational opportunities that can be critical in emergency settings. Starting to assess as soon as the patient arrives negates the advantage of gathering vital cues while approaching. Completing the primary assessment first can lead to missed observations that may guide the immediate response. Finally, limiting the assessment process to conscious patients overlooks the potential to gain critical information about those who may be unconscious or in distress before reaching full engagement. Thus, the optimal moment for forming a general impression is indeed while making approach.
