AAbnormal appearance and work of breathing only — respiratory failure
BAbnormal circulation to skin only — decompensated shock without respiratory involvement
CAbnormal work of breathing and circulation to skin — likely cardiopulmonary failure
DAll three PAT components normal — stable patient
✓ Correct answer: C. Abnormal work of breathing and circulation to skin — likely cardiopulmonary failureThe simultaneous presence of severe increased work of breathing (frothy sputum, crackles, refractory hypoxia) and signs of poor perfusion (low BP, pale or mottled skin) indicates abnormality in both work of breathing and circulation to skin, reflecting combined cardiopulmonary failure — a finding that mandates the most aggressive intervention.
