A mother brings her child for nitrous oxide sedation; the child has eaten recently. After discussing the situation, what is the MOST appropriate approach?

Give an antiemetic first, then proceed
Proceed — nitrous oxide is safe at any time
Cancel and reschedule with proper fasting instructions
Explain the risks (nausea/vomiting) to the mother and proceed only with her consent

Show answer and explanation

Correct answer: D. Explain the risks (nausea/vomiting) to the mother and proceed only with her consent

Nitrous oxide after eating increases nausea/vomiting risk. Appropriate approach: inform the mother of specific risks, obtain informed consent, then proceed if she agrees. Source confirms: 'Náusea y vómitos, need consent.'

A. Giving antiemetics without parent consent discussion is inappropriate.
B. Proceeding without discussing risks is inappropriate — parent must be informed.
C. Cancellation is the cautious option but NOT the only correct approach if consent is obtained.
D. CORRECT. Explain risks (N/V) to mother, obtain consent, then proceed. Informed consent is the key requirement.
