Final answer:
To help expel mucus in a client recovering from viral pneumonia, it is crucial to avoid cough suppressants and to use methods that thin and loosen mucus, such as staying hydrated and possibly engaging in chest physiotherapy under professional guidance.
Step-by-step explanation:
To aid in expelling mucus from the body of a client recovering from viral pneumonia, it is advisable to engage in methods that help thin and loosen the mucus, thereby facilitating its expulsion through coughing. Since the client still has a productive cough with mucus, the use of cough suppressants would be counterproductive, as it would suppress the cough reflex that is essential for clearing the mucus from the airways. Instead, measures that enhance the mucociliary escalator system should be adopted, which includes staying hydrated by drinking plenty of fluids, using humidifiers, and perhaps engaging in controlled breathing techniques that help mobilize secretions. While specific strokes or chest physiotherapy techniques such as percussion and postural drainage can be helpful, these should be conducted by trained professionals to ensure effectiveness and safety.
