A. Encourage client to drink water: While hydration is important for thinning secretions in COPD, encouraging fluid intake in a client experiencing acute respiratory distress may not be appropriate initially. The client’s dry mouth could be a result of mouth breathing due to hypoxia, but airway and breathing must be prioritized before addressing hydration. B. Assist client to an upright position: Positioning the client upright (high Fowler’s) maximizes lung expansion and improves diaphragmatic movement, which facilitates better oxygenation. It is the most immediate and appropriate intervention to alleviate shortness of breath and anxiety caused by hypoxia. This intervention also helps reduce the work of breathing in COPD patients. C. Apply a high-flow venturi mask: Although a Venturi mask delivers precise oxygen concentrations, high-flow oxygen can suppress the hypoxic drive in COPD clients. Oxygen should be titrated carefully in these clients, usually starting with low-flow oxygen and adjusted per blood gas results and should be guided by assessment, including pulse oximetry and arterial blood gas results. D. Administer a prescribed sedative: Sedatives can suppress respiratory drive, particularly in older adults and those with chronic respiratory conditions like COPD. Although anxiety is present, addressing the underlying cause, hypoxia, should take priority. Sedatives should be used cautiously and only after stabilizing respiratory function.
