Final answer:
Nitrous oxide is used to provide anesthesia to relieve pain during the treatment of extensive burn injuries in children.
Step-by-step explanation:
The correct answer is c. Provide anesthesia. Nitrous oxide is commonly used as an anesthetic agent to relieve pain during medical procedures, including the treatment of extensive burn injuries in children. Its primary purpose is not to promote healing directly, to prevent infection, or to improve urinary output; rather it serves to ensure that the patient does not experience pain during treatment. By providing anesthesia, nitrous oxide makes it possible for healthcare providers to perform necessary interventions without causing additional distress to the patient.
The purpose of administering nitrous oxide to a child with extensive burn injuries is to provide anesthesia. Nitrous oxide is commonly used as an anesthetic to induce a state of unconsciousness and reduce pain during surgical procedures or medical treatments.
