Final answer:
The best practice for ensuring the accuracy of insulin doses in a nursing setting is to check the insulin dose with another licensed nurse. This 'double-check' procedure adds a critical layer of safety to prevent medication errors.
Step-by-step explanation:
To ensure the accuracy of insulin doses according to nursing best practices, action should be taken to check the insulin dose with another licensed nurse. This is a safety protocol known as the 'double-check' procedure, which minimizes the risk of medication errors.
The nurse's judgment is important, but verification and collaboration with peers provide an essential layer of safety in patient care.
Consulting with the patient's family may be important for other aspects of care, but they should not be relied upon for medical dosing information.
Additionally, administration of an insulin dose without any verification is not considered a best practice and increases the risk of potentially harmful dosing errors.
