What should practitioners do before administering nitrous oxide?

Before administering nitrous oxide, obtaining informed consent is essential. Informed consent involves explaining the risks, benefits, and alternatives of the procedure to the patient, ensuring they understand what to expect and allowing them to make an educated decision regarding their treatment. This process not only safeguards the patient's autonomy but also helps in building trust between the practitioner and the patient, as well as minimizing legal risks for the practitioner.

When a patient is informed about nitrous oxide sedation, they are more likely to have realistic expectations and may feel more at ease. Furthermore, obtaining informed consent ensures that the patient is aware of their medical history and any relevant contraindications that could affect their treatment, facilitating safer and more effective care. This process stands in contrast to the other options, which either underplay the necessary precautions or eliminate vital patient evaluations.
