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 D
Explanation
Choice A rationale
Urinating only once or twice a day is not a typical symptom of type I diabetes mellitus. In fact, frequent urination is a common symptom of diabetes.
Choice B rationale
Rapid weight gain is not typically associated with type I diabetes mellitus. On the contrary, unexplained weight loss is a common symptom.
Choice C rationale
Refusing to eat favorite meals is not a typical symptom of type I diabetes mellitus. Changes in appetite can occur in various conditions, but they are not specific to diabetes.
Choice D rationale
Drinking more fluids than usual, also known as polydipsia, is a common symptom of type I diabetes mellitus. This is often accompanied by polyuria (frequent urination) due to high blood sugar levels.
Correct Answer is B
Explanation
Choice A rationale
Monitoring leukocytes, neutrophils, and thyroxine is not the most crucial for a patient with end-stage renal disease (ESRD). While these lab values can provide information about the patient’s immune function and thyroid function, they do not directly relate to the patient’s renal function.
Choice B rationale
Monitoring serum potassium, calcium, and phosphorus levels is crucial for a patient with ESRD. These electrolytes are typically excreted by the kidneys, and their levels can become imbalanced in patients with ESRD. Imbalances can lead to serious complications, such as cardiac arrhythmias and bone disease.
Choice C rationale
Monitoring erythrocytes, hemoglobin, and hematocrit is important for a patient with ESRD, as these patients often develop anemia due to decreased erythropoietin production by the kidneys. However, these are not the only lab values that should be monitored in these patients.
Choice D rationale
Monitoring blood pressure, heart rate, and temperature is important for all patients, but these are not specific to patients with ESRD. Patients with ESRD are at risk for electrolyte imbalances, which can affect cardiac function, making monitoring of serum potassium, calcium, and phosphorus levels more crucial.
