Final answer:
The nurse's responsibility is to ensure the correct procedural checks and confirmations are made before and after a surgical procedure, not to draw up insulin.
Step-by-step explanation:
In the context of obtaining consent for a surgical procedure, the responsibility of the nurse revolves around ensuring that the correct medication and dosages are administered to the patient, rather than directly involving the injection process itself. Therefore, among the options provided:
Option 3: Withdraw the correct dose of regular insulin from the bottle
This action aligns with the nurse's responsibility regarding medication administration. Nurses are responsible for accurately withdrawing the prescribed dosage of medications for patients. In this scenario, withdrawing the correct dose of regular insulin from the bottle is within the nurse's scope of practice, as long as the order and dosage have been appropriately prescribed by the healthcare provider.
Options 1 and 2 involve injecting air into insulin bottles, which is not typically a part of the consent process and is more related to the preparation of insulin. Option 4 entails withdrawing the correct dose of NPH insulin, which is also a responsibility of the nurse but in this specific context of obtaining consent for a surgical procedure, the focus is primarily on ensuring the accurate withdrawal of the specified medication (in this case, regular insulin) in the correct dosage.
