Final answer:
In response to the question on oxygen therapy administration, evidence-based practice dictates regulating oxygen via nasal cannula at no more than 6 L/min, continuously monitoring patient's oxygen saturation, and not allowing patients to self-adjust flow rates.
Step-by-step explanation:
When discussing evidence-based practice principles for the administration of oxygen therapy, a nurse should include several key actions. Firstly, oxygen should be regulated via nasal cannula at a flow rate of no more than 6 L/min, as higher flow rates can cause mucosal drying and discomfort without significantly increasing oxygenation. Additionally, it's important to always monitor the oxygen saturation of patients on oxygen therapy using devices like a pulse oximeter to ensure sufficient ventilation and appropriate oxygen delivery. This ensures that the respiratory system can accommodate the oxygen demands of the body efficiently while preventing carbon dioxide buildup.
Allowing patients to adjust their oxygen flow based on personal comfort is not advisable, as oxygen therapy needs to be titrated based on clinical indicators, not just the patient's perceived comfort. This is crucial, especially considering that a sensation of needing to breathe is often more influenced by carbon dioxide levels than oxygen levels. Using a flow rate higher than 6 L/min should be done with caution and typically reserved for patients with respiratory distress under proper medical supervision to enhance oxygenation, considering the principles of the work of breathing and gas exchange in the alveoli.
