What are two reasons a nurse may need to pull medication from an ADS cabinet using override?

A nurse may need to pull medication from an Automated Dispensing System (ADS) cabinet using override primarily when the order has not been entered or verified in the electronic health record system, such as Epic. This scenario typically arises in urgent situations where a medication is needed immediately, but there hasn't been sufficient time to go through the standard verification process.

Using an override allows the nurse to access the necessary medication quickly to ensure the patient's immediate needs are met, particularly in emergency situations where a delay in administering medication could have adverse outcomes. It’s a critical feature for patient care, balancing the need for timely medication with safety protocols.

In this context, the other options suggest situations that do not warrant an override. For example, if an order has been verified and is ready, it implies that the normal protocol can be followed without the need for an override. Similarly, if medication is in short supply or the patient has already taken the medication, these scenarios do not justify bypassing the system's safeguards by using an override.
