A client is being seen for chest congestion, coughing up thick secretions, and shortness of breath for several days and is diagnosed with pneumonia. The client has a one-pack-per-day smoking habit. What would be the priority nursing diagnosis for this client?

A. Ineffective airway clearance AEB client coughing up thick, yellow secretions: While this statement identifies the symptom, it does not include the underlying cause. Nursing diagnoses should specify both the problem and the etiology to guide appropriate interventions, making this formulation incomplete. B. Ineffective airway clearance R/T tracheobronchial secretions AEB client coughing up thick, yellow secretions: This diagnosis clearly identifies the priority problem (ineffective airway clearance), the etiology (tracheobronchial secretions), and the evidence (thick, yellow secretions). Addressing airway clearance is critical in pneumonia to prevent hypoxia, respiratory distress, and further infection complications. C. Ineffective breathing pattern AEB client states, "I am short of breath.": While shortness of breath is concerning, it is a symptom rather than the underlying physiologic issue. Focusing on airway clearance directly addresses the pathophysiology of pneumonia and secretion buildup, which is more urgent than the subjective report of dyspnea alone. D. Ineffective health maintenance R/T smoking: Although smoking is a contributing factor to pulmonary compromise, it is a long-term risk factor and not the immediate priority. Interventions targeting acute airway clearance take precedence over health maintenance in this acute pneumonia episode.
