Which patient is breathing adequately?

• A. A conscious male with respirations 19 breaths/min and pink skin
• B. A nonresponsive patient with agonal breaths
• C. A patient with respirations 9/min and pale skin
• D. A patient with apnea

Answer: (A)

Adequate breathing means the patient is ventilating well enough to meet metabolic needs. Key signs are a normal adult rate (roughly 12–20 breaths per minute), regular rhythm, and skin color that indicates good oxygenation and perfusion. The description of a conscious adult with a breathing rate of 19 breaths per minute and pink skin fits this best: the rate is within normal limits, the patient is alert, and pink skin suggests adequate oxygen delivery. The other scenarios show problems: agonal breaths are irregular and typically ineffective; a breathing rate of 9 per minute with pale skin points to hypoventilation and poor perfusion; and no breathing at all means ventilation is absent.
