Final Answer:
The nurse should anticipate observing Option 4: Gradual onset of nonproductive cough in a client diagnosed with atypical pneumonia.
Step-by-step explanation:
Atypical pneumonia, also known as walking pneumonia, is commonly caused by bacteria such as Mycoplasma pneumoniae. Unlike typical pneumonia, atypical pneumonia often presents with a gradual onset of symptoms, and a nonproductive cough is a characteristic feature. This means that the client may experience a slow development of respiratory symptoms, including a cough that does not produce significant amounts of sputum.
In atypical pneumonia, the absence of high fever and chills, as described in Option 2, is notable. While fever can occur, it tends to be lower-grade compared to other types of pneumonia. Additionally, a productive cough with purulent sputum, as mentioned in Option 1, is more commonly associated with bacterial infections such as typical pneumonia rather than atypical pneumonia. Chest pain exacerbated by coughing, as stated in Option 3, is not a typical symptom of atypical pneumonia and may be more indicative of other respiratory conditions.
In summary, the nurse should be alert to the gradual onset of a nonproductive cough when assessing a client with atypical pneumonia. This understanding helps guide appropriate nursing interventions and contributes to accurate patient care in managing respiratory symptoms associated with atypical pneumonia.
