Correct answer: C — Use CAM-ICU or ICDSC, then obtain expert diagnostic confirmation
Explanation lettering: C = shown as A · D = shown as C · E = shown as D · A = shown as E
D is correct. NICE specifies CAM-ICU or ICDSC in critical care and the recovery room; a clinician with relevant expertise confirms the diagnosis. A is not a delirium diagnostic pathway. B seeks a possible precipitant and cannot diagnose delirium. C incorrectly applies the ward 4AT to recovery. E loses the opportunity for timely recognition.
