M29: Nitrous oxide for an anxious child, and the pain plan for home: health check, consent, hood and titration, monitoring, oxygen at the end, medicine without codeine

One visit for an anxious child who needs a tooth out: read whether nitrous oxide fits (fear, a strong gag, nose breathing, the health history), record the parent's consent and give the diet instructions, fit the nasal hood, set the flow for the child's age, start with 100% oxygen and titrate the nitrous oxide in 10% steps, keep it at or under 50% while watching responsiveness, color and breathing, give 100% oxygen for at least 5 minutes at the end and discharge only when the child is back to baseline, then write the pain plan for home: an NSAID such as ibuprofen first, dosed by weight, acetaminophen alongside it if needed, no codeine or tramadol, read against the AAPD nitrous oxide best practices and the ADA children's acute dental pain guideline.
