If I took one vicodin 5mg on wed night and one on Thursday will I pass a urine drug test on Monday night

Probably. Vicodin (acetaminophen and hydrocodone) probably wouldn't be detected in a standard UDT at any time interval. However if they test for semi-synthetics (a special low threshold test) then they would be looking for hydromorphone.

Unless you are a regular or heavy user, you will fall at the lower end of detection time, being about 2-4 days.

Mayo Clinic, see hydromorphone
