In a scenario involving a male client with metastatic lung cancer who is experiencing signs of respiratory distress, administering analgesic medications as needed is the most appropriate nursing intervention. This approach recognizes that patients with advanced cancer often experience significant pain, which can exacerbate feelings of distress and may contribute to respiratory difficulties.

The use of analgesics serves multiple purposes in this context: it helps to manage pain effectively, thereby alleviating some of the stress on the client's respiratory system. In turn, effective pain management can make it easier for the client to breathe, as pain and anxiety are closely linked and can lead to increased respiratory effort and discomfort.

Additionally, while other interventions may be appropriate in different circumstances, they carry potential drawbacks or are not as immediately beneficial in providing relief for the client's distress. For instance, intubation is an invasive procedure that may not be suitable or in alignment with the client's goals of care, particularly for someone in advanced stages of terminal illness. High-flow oxygen might temporarily increase oxygen saturation but may not address underlying pain or discomfort. Encouraging deep breathing exercises, although beneficial in many situations, may not be practical or effective for a client who is in significant distress or unable to cooperate due to pain.

Thus, prioritizing analgesics addresses both the
