What statement indicates a lack of understanding about managing dyspnea at end of life?

A statement indicating a lack of understanding about managing dyspnea at the end of life is the one that suggests continuing oxygen therapy even if it is not effective. In palliative care, the goal is to enhance the quality of life and comfort for patients. If a treatment, such as oxygen therapy, is not providing relief from dyspnea, it is not only ineffective but can also cause additional distress or agitation for the patient.

In such contexts, healthcare professionals focus on interventions that actually bring relief and comfort rather than persisting with treatments that do not yield positive results. The other options demonstrate a good understanding of managing dyspnea:

Positioning the patient upright utilizes gravity to aid in lung expansion and can significantly enhance their ability to breathe. Providing cool air can also help alleviate the sensation of breathlessness, as the cooler temperature may have a calming effect on the patient. Additionally, opioids are well-recognized in the management of dyspnea and respiratory distress, as they can depress the respiratory drive to some extent and reduce the perception of breathlessness, thereby improving comfort.
