A client with a large pleural effusion undergoes a thoracentesis. Following the procedure, which assessment finding warrants immediate intervention by the nurse?

  • A. The client has asymmetrical chest wall expansion
  • B. The client complains of pain at the insertion site
  • C. The client's chest x-ray indicates decreased pleural effusion
  • D. The client's arterial blood gases show pH 7.35, PaO2 85, PaCO2 35, HCO3 26
Correct Answer: A

Rationale: Asymmetrical chest wall expansion is a critical finding post-thoracentesis as it may suggest a pneumothorax, requiring immediate intervention to prevent further complications. The other options, such as pain at the insertion site (Choice B), decreased pleural effusion on chest x-ray (Choice C), and normal arterial blood gases within acceptable ranges (Choice D) do not indicate an immediate need for intervention like asymmetrical chest wall expansion does.
