Final answer:
When a nurse notes 'resume previous medications' on a client's record, they should verify the medications on the client's medication administration record.
Step-by-step explanation:
When a nurse notes 'resume previous medications' on a client's record, the action the nurse performs is to verify the medications on the client's medication administration record. This involves checking the client's medication chart to ensure that the previous medications are listed correctly and can be resumed as per the healthcare provider's orders. It is important for the nurse to confirm that the medications are accurately recorded before continuing the client's medication regimen.
