While caring for a toddler receiving oxygen via face mask, the nurse observes that the child's lips and nares are dry and cracked. Which intervention should the nurse implement?

A. Ask the mother what she usually uses on the child's lips and nose: While this respects family input, the nurse must prioritize using safe, evidence-based interventions appropriate for oxygen therapy and mucosal dryness. B. Apply a petroleum jelly to the child's nose and lips: Petroleum-based products are flammable and should not be used near oxygen delivery devices due to the risk of fire or combustion. C. Use a topical lidocaine analgesic for cracked lips: Lidocaine is not appropriate for dry or cracked lips in toddlers and can pose a risk of toxicity or allergic reaction, especially with frequent use. D. Use a water soluble lubricant on affected oral and nasal mucosa: Water-soluble lubricants are safe to use with oxygen therapy because they are non-flammable and effectively relieve dryness and irritation of mucous membranes.
