Which item is part of objective data for oxygenation/perfusion?

• A. Respiratory rate
• B. Chest pain
• C. Sputum color
• D. Fatigue

Answer: (A)

In assessing oxygenation and perfusion, focus on data you can measure directly. Respiratory rate is a clear objective data point because you can count breaths per minute, observe the pattern, regularity, and effort, and see how these relate to the patient’s ventilation status. Changes in rate often reflect how well oxygen is being delivered and whether the body is compensating for hypoxemia or respiratory distress.

Chest pain and fatigue are subjective experiences the patient reports, which, while important, are not objective measurements. Sputum color can be observed, but it’s more of a descriptive sign related to airway or infectious processes rather than a direct measure of oxygenation or perfusion. So, the item that best represents objective data for oxygenation/perfusion is the respiratory rate.
