A 10-year-old child with pneumonia is receiving oxygen at 5 L/minute via a nasal cannula.
When planning care for this child, what principle of oxygen administration should the nurse keep in mind?
Avoid administering oxygen at high levels for extended periods.
Increase the oxygen rate during sleep to compensate for a slower respiratory rate.
Taking a sedative at bedtime slows the respiratory rate, which decreases oxygen needs.
Oxygen is less toxic when it is humidified with a hydration source.
The Correct Answer is A
Choice A rationale
Oxygen therapy is a crucial part of the management for patients with severe pneumonia. However, prolonged administration of high concentrations of oxygen can potentially lead to oxygen toxicity, resulting in damage to the cells of the lungs. This is due to the production of
reactive oxygen species which can damage cell structures. Therefore, it is important to avoid administering oxygen at high levels for extended periods.
Choice B rationale
While it might seem logical to increase the oxygen rate during sleep due to a slower respiratory rate, this is not typically recommended. The body’s oxygen requirements do not significantly change during sleep and increasing the oxygen rate could potentially lead to hyperoxia.
Choice C rationale
Sedatives can indeed slow the respiratory rate, but this does not decrease oxygen needs. In fact, it could potentially lead to respiratory depression and hypoxia, especially in a patient with a respiratory illness like pneumonia.
Choice D rationale
Humidification of oxygen can improve patient comfort, especially with high flow rates, by preventing dryness in the nasal passages. However, it does not make oxygen less toxic.

Correct Answer is C
Explanation
Choice A rationale
Replacing the IV site with a smaller gauge is not the most appropriate intervention in this situation. The client’s confusion and picking at the dressing and tape are likely due to the dementia and increased confusion at night, known as “sundowning”. While a smaller gauge might be less noticeable to the client, it does not address the primary issue of the client’s confusion and restlessness at night.
Choice B rationale
Applying soft bilateral wrist restraints might be considered in some situations to prevent a confused client from removing necessary medical devices. However, restraints should be a last resort after all other interventions have been tried because they can increase agitation and confusion, and they pose a risk for injury.
Choice C rationale
Redressing the abdominal incision is the correct choice. The dressing is no longer occlusive, which means it’s not providing a proper barrier to bacteria. This could lead to an infection in the surgical site. The nurse should clean the area and apply a new sterile dressing.
Additionally, the nurse should continue to monitor the client’s behavior and implement interventions to reduce confusion and restlessness, such as reorienting the client and providing a quiet and calm environment.
Choice D rationale
Leaving the lights on in the room at night can actually increase confusion and agitation in clients with dementia. It can disrupt the client’s sleep-wake cycle and make “sundowning” worse. Therefore, this is not the most appropriate intervention.
Correct Answer is A
Explanation
Choice A rationale
Monitoring the patient’s cardiac activity via telemetry is the most important intervention for a patient with acute renal failure (ARF), uncontrolled type 1 diabetes mellitus, and hyperkalemia who is receiving an IV dose of regular insulin. Hyperkalemia can cause cardiac arrhythmias and other cardiac complications. Therefore, continuous cardiac monitoring is crucial to detect any changes in heart rhythm or rate that could indicate worsening hyperkalemia.
Choice B rationale
While assessing glucose via fingerstick every 4 to 6 hours is important for a patient with uncontrolled type 1 diabetes mellitus, it is not the most important intervention in this scenario. The patient’s hyperkalemia and ARF pose more immediate risks.
Choice C rationale
Evaluating hourly urine output for return of normal renal function is an important part of monitoring a patient with ARF34. However, in the context of hyperkalemia and the administration of insulin, cardiac monitoring is more critical.
Choice D rationale
Maintaining venous access with an infusion of normal saline is a standard nursing intervention for most hospitalized patients, but it is not the most important intervention in this scenario.
