What does the administration of Nitrous Oxide commonly achieve in a medical setting?

The administration of Nitrous Oxide is primarily recognized for its ability to provide pain relief and sedation. This colorless, non-flammable gas is often utilized in various clinical settings, particularly in dentistry and during minor surgical procedures. Its analgesic properties help alleviate discomfort while simultaneously inducing a state of relaxation and light sedation in patients, making it an effective choice for those who may experience anxiety or pain during treatment.

In contrast, other options like restoration of breathing are associated with different gases or treatments, where anesthetics or respiratory support methods are more applicable. The reduction of fever typically involves antipyretic medications rather than gas therapy, as fever management focuses on addressing the underlying infection or condition causing the elevated temperature. Similarly, combating infection usually requires antibiotics or antiviral medications rather than gas administration, as gases do not possess antimicrobial properties. Thus, the role of Nitrous Oxide in providing both analgesia and a degree of sedation clearly supports its designation as the correct answer.
