Which statement about nitrous oxide-oxygen sedation monitoring is true?

Explanation:
Monitoring nitrous oxide-oxygen sedation requires keeping the airway clear, ensuring adequate oxygen delivery, and confirming effective ventilation. If the nasal passages are blocked, the patient won’t receive the intended gas mixture, which can undermine sedation and safety. Watching for signs of hypoxia is essential because declining oxygenation can occur even with careful dosing; continuous oxygen saturation monitoring helps detect early hypoxemia. In addition, ongoing assessment of oxygenation and ventilation—using pulse oximetry and, when possible, end-tidal CO2 or other respiratory parameters—allows detection of hypoventilation or evolving respiratory compromise before it becomes serious. Because all of these aspects are necessary to keep the patient safe, the best choice is all of the above.
