Sounds like they were just questioning overdose and wanted to see if it made a difference, sometimes a patient "appears" to respond to a first dose of narcan so they try another dose. Is it possible they gave the narcan prior to receiving the Utox results? On another note, I've seen a 5150 patient arrive in the department shortly after guzzling a bunch of pills, the initial Utox was gathered right away and came back clean but they ended up on a narcan drip.
