What are two reasons why a nurse might need to pull a medication from an ADS cabinet on override?
a) Pharmacy is closed and unavailable for verification; the medication is needed urgently.
b) The patient refuses to take the medication; the prescriber is unreachable for clarification.
c) The medication is out of stock in the pharmacy; the patient's condition requires immediate treatment.
d) The patient's insurance does not cover the prescribed medication; pharmacy assistance is unavailable.
