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 B
Explanation
Choice A rationale
While constipation due to immobility can be a concern for a client diagnosed with Parkinson’s disease, it is not the highest priority. The nurse should ensure that the client has a diet high in fiber and drinks plenty of fluids to prevent constipation. Regular physical activity can also help to stimulate bowel movements. However, this is not the most critical issue that needs to be addressed.
Choice B rationale
The risk for aspiration due to muscle weakness is the highest priority for a client diagnosed with Parkinson’s disease. This is because Parkinson’s disease can cause difficulties with swallowing, which can lead to aspiration. Aspiration can lead to serious complications such as pneumonia. The nurse should monitor the client for signs of difficulty swallowing and aspiration. The client may need to be referred to a speech therapist for a swallowing evaluation and may need modifications to their diet to make swallowing easier.
Choice C rationale
While impaired physical mobility due to muscle rigidity can be a concern for a client diagnosed with Parkinson’s disease, it is not the highest priority. The nurse should encourage the client to engage in regular physical activity to help manage muscle rigidity. Physical therapy may also be beneficial. However, this is not the most critical issue that needs to be addressed.
Choice D rationale
While a self-care deficit due to motor disturbance can be a concern for a client diagnosed with Parkinson’s disease, it is not the highest priority. The nurse should assess the client’s ability to perform activities of daily living and provide assistance as needed. Occupational therapy may also be beneficial. However, this is not the most critical issue that needs to be addressed.
Correct Answer is A
Explanation
Choice A rationale
Testing the fluid on the dressing for glucose is the immediate course of action when a nurse notices clear fluid on the surgical dressing of a patient who has just returned from lumbar spinal surgery. Clear fluid could be cerebrospinal fluid (CSF), which contains glucose. If the fluid is positive for glucose, it could indicate a CSF leak, which requires immediate medical attention.
Choice B rationale
Changing the dressing using a compression bandage is not the immediate course of action. The source of the fluid needs to be identified first.
Choice C rationale
Marking the drainage area with a pen and continuing to monitor is not the immediate course of action. The source of the fluid needs to be identified first.
Choice D rationale
Documenting the findings in the electronic medical record is important, but it is not the immediate course of action. The source of the fluid needs to be identified first.
