When should the lead pharmacy technician reorder billing forms if 80% of a full case (20 packages) has been used?

In this scenario, the lead pharmacy technician needs to calculate the remaining quantity of billing forms after using 80% of a full case, which consists of 20 packages. When 80% of the forms have been utilized, this equates to 16 packages. To determine how many packages are left, you subtract the 16 packages used from the total of 20 packages, leaving you with 4 packages remaining.

Given that it's important to reorder when stock reaches a certain threshold, the lead pharmacy technician would look to reorder enough to bring the inventory back to the full 20 packages. Since there are currently 4 packages left, the technician would need to reorder an additional 16 packages to reach full stock.

Therefore, the choice that correctly reflects how many more packages they should reorder to replenish their stock after reaching the 80% usage mark is indeed 4 packages. This emphasizes the importance of monitoring inventory levels and ensuring that sufficient stock is on hand to avoid shortages.
