Question: A client undergoes a thoracentesis for pleural effusion. Thirty minutes after the procedure, the nurse assesses the client. Which finding requires immediate intervention?

Answer options:

• Mild pain at the insertion site, rated 3/10. ✅ Respiratory rate of 28 breaths per minute, with shallow respirations.
• Small amount of serosanguinous drainage on the dressing.
• Oxygen saturation of 94% on room air.

Correct answer: Respiratory rate of 28 breaths per minute, with shallow respirations.

Explanation: A respiratory rate of 28 breaths per minute with shallow respirations after a thoracentesis can indicate a pneumothorax or further compromise in lung expansion, requiring immediate assessment and intervention. Mild pain and minimal drainage are expected findings, and an oxygen saturation of 94% on room air is generally acceptable.
