Oxygen at 5 L/minute per nasal cannula is being administered to a 10-year-old child with pneumonia. When planning care for this child, which principle of oxygen administration should the nurse consider?
Oxygen is less toxic when it is humidified with a hydration source.
Avoid administration of oxygen at high levels for extended periods.
Increase oxygen rate during sleep to compensate for slower respiratory rate.
Taking a sedative at bedtime slows respiratory rate, which decreases oxygen needs.
The Correct Answer is B
A. Oxygen is less toxic when it is humidified with a hydration source. While humidification can prevent drying of the respiratory mucosa, it does not directly relate to the principle of avoiding high levels of oxygen for extended periods.
B. Avoid administration of oxygen at high levels for extended periods. This is the correct principle. Prolonged exposure to high levels of oxygen can lead to oxygen toxicity, which can cause lung damage. Oxygen therapy should be titrated to maintain adequate oxygenation without exposing the patient to excessive oxygen levels.
C. Increase oxygen rate during sleep to compensate for slower respiratory rate. This statement is incorrect. Oxygen therapy should be adjusted based on the patient's oxygen saturation levels and respiratory status, not solely on sleep patterns.
D. Taking a sedative at bedtime slows respiratory rate, which decreases oxygen needs. While sedatives can depress respiratory rate, leading to decreased oxygen needs, this is not a general principle of oxygen administration. Oxygen therapy should be based on the patient's oxygenation needs rather than medications they are taking.

Correct Answer is A
Explanation
A. Placing padding around the cannula tubing is the appropriate intervention to address the erythema under the chin. This padding can help alleviate pressure and reduce skin irritation caused by the tubing. It's a proactive measure to prevent further discomfort or skin breakdown.
B. Decreasing the flow rate to 1 L/minute might not address the issue of pressure-related erythema, and it could compromise the client's oxygenation if not clinically indicated.
C. Applying lubricant to the tubing may not effectively reduce pressure or irritation caused by the tubing under the chin.
D. Discontinuing the use of the nasal cannula should be reserved for situations where it is medically necessary or if an alternative oxygen delivery method is available.
