Which vital sign is typically measured first in a patient assessment?

In a patient assessment, the vital sign that is typically measured first is the respiratory rate. Monitoring the respiratory rate is crucial because it provides immediate insights into the patient's respiratory function and overall oxygenation status. Observing how often the patient breathes can alert the healthcare provider to potential respiratory distress, which is a critical and time-sensitive situation.

In practice, assessing the respiratory rate is unobtrusive, allowing for a more natural observation of the patient's breathing pattern as it can be measured without drawing attention to it, ensuring that the results are more reflective of the patient's normal state. After establishing the respiratory rate, the clinician can proceed to other vital signs that may also indicate the patient’s condition, but addressing any breathing issues immediately is often prioritized in clinical settings. This rationale underscores the significance of the respiratory rate in patient assessments.
