In protocol N3, new onset ALOC is defined as GCS less than what value?

• A. 13
• B. 15
• C. 14
• D. 12

Answer: (C)

The main idea here is understanding the cutoff used to flag altered mental status on the Glasgow Coma Scale in protocol N3. The Glasgow Coma Scale runs from 3 to 15, with 15 being fully awake and oriented. In protocol N3, new onset ALOC is defined as a score below 14, meaning 13 or lower. This boundary ensures that even a small decrease from normal (for example, dropping from 15 to 13) is recognized as a change in mental status that needs attention, while a score of 14 is not yet considered new onset ALOC. So the threshold value used is 14, because the condition is met only when the GCS is strictly less than 14.
