NVQ Level 3 Dental Nursing Practice Exam

The key idea is that the sedation session must be recorded in full to ensure safety, accountability, and continuity of care. When nitrous oxide/oxygen is used, you should document how the session was given, how the patient responded, and what happened during recovery. This means noting the administration details—the gas mixture used, the flow rates, the start time and any adjustments made, and the total duration. You also record the patient’s vitals throughout the procedure (for example, heart rate, blood pressure, respiratory rate, oxygen saturation) and how the patient moved through the recovery phase, including how long it took to return to baseline and any observations about recovery quality. Any adverse events, actions taken, and the discharge criteria met (and post-operative instructions) should be included as well. This level of documentation protects the patient, supports clinical decisions, and fulfills legal and professional standards.

Options that mention only the patient’s name, or that no documentation is needed, or that focus solely on machine calibration data, do not capture the essential information about how the sedation was delivered and how the patient fared, which is why they are insufficient.
