Treating SpO2 as ventilation status; carbon dioxide retention requires ventilation assessment and ABG/VBG context when ordered.
Airway, alveoli, blood, brain: air must move, gases must diffuse, blood must carry oxygen, and the brainstem adjusts ventilation.
University-level NCLEX-RN respiratory lesson: Anatomy and Physiology of the Respiratory System — pathophysiology, ABGs, imaging, pharmacology, and clinical judgment.
For Anatomy, connect the assessment cue to the immediate risk before selecting an action for RN. Start with stability, ABCs, neurologic change, medication risk, infection risk, and scope of practice. Then decide whether the safest next step is assess, intervene, escalate, teach, or evaluate response.
A missed priority in Anatomy can delay recognition of deterioration or allow preventable harm to continue. Safety focus: Airway, alveoli, blood, brain: air must move, gases must diffuse, blood must carry oxygen, and the brainstem adjusts ventilation.

In a Anatomy item, explain the first cue you noticed, the complication it predicts, the nursing action within scope, and the finding that proves the response worked.
Treating SpO2 as ventilation status; carbon dioxide retention requires ventilation assessment and ABG/VBG context when ordered. This keeps Anatomy reasoning tied to client safety instead of recall-only studying.
