Final answer:
To address dry and cracked lips and nares in a toddler receiving oxygen via face mask, the nurse should implement measures to moisturize the lips and nares, use a humidifier to increase humidity, and encourage the child to drink fluids to maintain hydration.
Step-by-step explanation:
The dry and cracked lips and nares in a toddler receiving oxygen via face mask may be due to the drying effect of the oxygen. To address this issue, the nurse should implement measures to moisturize the lips and nares. One intervention is to apply a water-based moisturizer, such as petroleum jelly or lip balm, to the lips and inside the nares. This will help to hydrate and protect the skin from further dryness and cracking.
Another intervention is to use a humidifier in the room to increase the humidity and prevent excessive drying of the nasal passages and lips. The humidifier should be set to an appropriate level as per the healthcare provider's recommendation.
Additionally, the nurse should encourage the child to drink fluids to maintain hydration and prevent dryness. This can be done by offering water or other appropriate fluids to the child frequently throughout the day.
