Which of the following describes the general appearance typically seen in smoke inhalation or CO poisoning?

Anxious describes the general appearance because, with smoke inhalation or carbon monoxide poisoning, the brain and tissues experience hypoxia. This often makes the patient restless, tense, and visibly uneasy as they respond to the lack of oxygen. Carbon monoxide binds to hemoglobin and reduces oxygen delivery, triggering a sympathetic response that manifests as anxiety or agitation. Cherry-red skin is a classic teaching point, but it’s not a reliable finding in living patients and isn’t consistently seen. Surface burns reflect external injuries rather than how the patient looks overall, so they don’t describe appearance. Tachypnea is a sign you would notice as a rapid breathing rate, a vital sign rather than how the patient appears.
