A client's respiratory assessment reveals crackles, decreased tactile fremitus, and a dull sound in left lower chest during percussion. Which condition should the nurse document in the electronic medical record?

A. Pleural effusion: The combination of crackles, decreased tactile fremitus, and dullness to percussion is most consistent with pleural effusion. Fluid in the pleural space dampens vibration transmission, decreases fremitus, and creates a dull percussion sound while causing adventitious breath sounds. B. Emphysema: Emphysema typically presents with hyperresonance on percussion due to air trapping, along with diminished breath sounds. Fremitus is decreased as well, but crackles and dullness are not characteristic findings. C. Bronchitis: Bronchitis may cause crackles or wheezes due to airway inflammation, but tactile fremitus is usually normal or increased, and percussion tones remain resonant. The dullness noted here makes bronchitis unlikely. D. Pneumothorax: Pneumothorax produces hyperresonant percussion sounds with absent or markedly decreased breath sounds. Fremitus is also decreased, but dullness and crackles are not expected, distinguishing it from pleural effusion.
