Final answer:
The nurse should discard the open, unlabeled vial of insulin and request a new one to ensure medication safety. The use of a medication without a clear expiration date is unsafe and against standard healthcare protocols.
Step-by-step explanation:
The nurse should discard the vial and request a new one from the pharmacy. Medications, especially insulin, must have clearly labeled expiration dates to ensure safety and efficacy. Using a medication without this information is not safe practice as it could be expired, leading to suboptimal treatment outcomes or posing a risk to the patient. Ensuring that medication safety protocols are followed is crucial in healthcare settings.
When a nurse reviews items aloud with the team, they are conducting a type of safety check to ensure that all procedures are followed correctly, similar to the checks done before administering medication. All materials used must be accounted for and appropriately labeled, including a focus on whether there are any issues with equipment to be addressed.
