A nurse is admitting a 47-year-old post-op patient with IV Ringer lactate 100 ml/hr, O2 4 L via nasal cannula, and a narcotic given 1 hour ago with nausea. What is the priority assessment as the patient is transferred to the unit?

• A. Check that the O2 is connected and check the flow rate
• B. Check blood pressure
• C. Call the physician
• D. Question the patient about nausea

Answer: (A)

The immediate priority is ensuring oxygen delivery to the patient. Oxygenation is critical, especially after surgery and when narcotics have been given, because opioids can depress respiration and increase the risk of hypoxia. By confirming that the oxygen setup is properly connected and the flow rate is correct, you ensure the patient is receiving the prescribed supplemental oxygen right away and reduce the chance of a rapid decline in oxygen saturation during transfer.

If the oxygen line were disconnected or the flow rate incorrect, the patient could desaturate quickly, which would take precedence over other concerns like blood pressure, calling the physician, or asking about nausea. Once the oxygen delivery is verified, you can attend to other assessments and needs, such as vital signs, pain and nausea, and consultations as needed.
