In a scenario where a patient’s saturation is low despite oxygen, which of the following is the most appropriate initial nursing action according to standard practice in acute care settings?

• A. Increase the oxygen delivery rate immediately.
• B. Call the physician to reconsider the treatment plan.
• C. Check the fit and placement of the oxygen delivery system.
• D. Arrange for arterial blood gas measurement.

Answer: (C)

When a patient on oxygen has a low saturation, the first thing to check is that the oxygen delivery system is properly fitted and placed. A quick inspection can reveal issues like a loose or mispositioned mask or nasal cannula, tubing that’s disconnected or kinked, or a wrong flow setting for the device. If oxygen isn’t actually reaching the patient because the setup is faulty, correcting the fit or connection can rapidly improve the saturation without changing treatment or ordering invasive tests. Only after ensuring the equipment is delivering oxygen would you proceed with further steps, such as adjusting flow, contacting the physician, or arranging arterial blood gas measurement, if the saturation remains low.
