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?

Pneumonia.

Pneumothorax.

Asthma.

Bronchitis.

Answer and Explanation

The Correct Answer is C

A. Pneumonia typically presents with fever, productive cough, and lung consolidation, not just wheezing and low oxygen saturation.
B. Pneumothorax usually causes sudden sharp chest pain and decreased breath sounds on the affected side, rather than wheezing and prolonged expiration.
C. Asthma is characterized by wheezing, prolonged expiration, and low oxygen saturation due to bronchoconstriction and inflammation. The client's symptoms are consistent with an asthma exacerbation.
D. Bronchitis presents with a productive cough and sometimes wheezing but does not typically cause such severe hypoxemia or a pronounced increase in respiratory rate as seen here.
