A client arriving to the emergency department reports trouble breathing and tightness in the chest that started while exercising at the gym. The nurse observes the client is afebrile, heart rate 96 beats/minute, respirations 32 breaths/minute, and pulse oximeter reading of 85%. Audible wheezing is heard on expiration with a decrease in tactile fremitus and bilateral breath sounds. The client displays intercostal retracting and prolonged expirations. Based on the findings, the nurse should recognize the client is exhibiting symptoms of which condition?

A. Pneumothorax. Pneumothorax (collapsed lung) typically presents with sudden-onset dyspnea, diminished or absent breath sounds on one side, and hyperresonance on percussion rather than bilateral wheezing and prolonged expirations. While pneumothorax can cause decreased tactile fremitus, it is not characterized by wheezing. B. Asthma. The client’s symptoms—including wheezing, prolonged expirations, chest tightness, dyspnea, tachypnea (32 breaths/min), and low oxygen saturation (85%)—are characteristic of an asthma exacerbation. Asthma causes airway inflammation, bronchoconstriction, and mucus production, leading to difficulty breathing, prolonged expiration, and intercostal retractions. C. Bronchitis. Acute bronchitis can cause wheezing and cough, but it is usually accompanied by productive sputum and fever in infectious cases. The absence of fever and the presence of chest tightness, expiratory wheezing, and accessory muscle use make asthma the more likely diagnosis. D. Pneumonia. Pneumonia typically presents with fever, productive cough, localized crackles, increased fremitus, and dullness on percussion. The decreased fremitus, wheezing, and absence of fever suggest an obstructive airway disorder like asthma, rather than an infectious process.
