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?

Choice A rationale Asking the mother about usual care practices might provide useful information, but it is not the best immediate intervention for addressing the child's dry and cracked lips and nares. Immediate action should be taken to provide relief. Choice B rationale Using a topical lidocaine analgesic is not appropriate for treating dryness and cracking of the lips and nares. Lidocaine is an anesthetic, not a moisturizing agent, and could cause additional irritation or adverse reactions if used improperly. Choice C rationale Applying petroleum jelly to the child's nose and lips is not recommended as it poses a risk of aspiration, especially in young children. Inhaling petroleum jelly can lead to respiratory issues and is therefore not a safe option. Choice D rationale Using a water-soluble lubricant is the best option for moisturizing and protecting the child's dry and cracked lips and nares. Water-soluble lubricants are safe for use on mucous membranes and provide effective relief without the risk of aspiration.
