The pharmacy technician is conducting the weekly controlled drug balance check. He runs out of time to complete the task so just fills in the last three sections knowing that these are slow moving controlled drugs and are never wrong. The next day the dispenser notices a discrepancy and asks if the pharmacy technician completed the CD balance check.
He said yes he did.
The investigation that followed revealed that the balance could not have been correct when the pharmacy technician checked it and was therefore found to have told a lie.
