Intra-operative nursing actions should include which of the following?

Continuous intravenous access and monitoring are vital components of intra-operative nursing actions. Maintaining IV access allows for the prompt administration of medications, including sedatives, anesthetics, and other necessary substances during the procedure. Additionally, continuous monitoring through IV can help assess the patient's response to these medications and any potential changes in their condition.

Monitoring also includes observing vital signs and ensuring that the patient remains stable throughout the surgery. This ongoing assessment is crucial for early detection of complications or adverse reactions to sedation or anesthesia. The consistency provided by continuous monitoring helps the surgical team make informed decisions and respond quickly to any issues that may arise.

In contrast, placing a patient in a prone position may not be appropriate depending on the specific surgical procedure being performed. Administration of fluids only at the end of the procedure is also not advisable as it could lead to complications; rather, fluid management is typically carried out throughout the surgery. Additionally, discontinuing oxygen therapy would jeopardize the patient's safety by increasing the risk of hypoxia during a time when oxygenation is critical.
