Which statement about dyspnea in patients at end of life is true?

The statement that dyspnea may be relieved by a cool fan blowing on the patient is accurate. In palliative care, managing symptoms such as dyspnea is crucial for enhancing the quality of life for patients at the end of life. The use of a cool fan can help alleviate the sensation of breathlessness by providing comforting airflow, which can create a perception of easier breathing. This simple intervention is often effective and can be implemented quickly, making it a valuable tool for nursing staff when addressing patient discomfort related to dyspnea.

The other options do not accurately reflect effective practices for managing dyspnea in this patient population. It is a misconception that dyspnea cannot be effectively managed; there are several treatment options available, including medications and non-pharmacological methods. Similarly, while dyspnea can be a symptom at the end of life, it is not always indicative of impending death, as it can occur due to various conditions. Lastly, positioning patients who are experiencing dyspnea is typically more beneficial when they are in an upright or semi-Fowler's position rather than supine, as this can promote better lung expansion and ease breathing.
