A nurse is assisting with the care of a client following a thoracentesis. Which of the following findings should the nurse identify as an indication of a possible complication?

This scenario involves a post-thoracentesis client who is at risk for invasive procedural complications like pneumothorax or hemothorax. The nurse must apply knowledge of respiratory pathophysiology and clinical signs of pleural space disruption to detect early respiratory compromise. Choice A rationale Bradycardia is not a typical complication of pleural fluid removal. Procedural pain, anxiety, or respiratory compromise usually triggers sympathetic nervous system activation, which results in tachycardia rather than a slow heart rate below 60 beats per minute. Choice B rationale Tachypnea indicates respiratory distress, signaling a potential pneumothorax, hemothorax, or re-expansion pulmonary edema. An elevated respiratory rate above 20 breaths per minute reflects compensatory hyperventilation due to impaired gas exchange or lung collapse. Choice C rationale Pedal edema reflects systemic fluid volume overload or right-sided heart failure. It is a chronic structural finding that does not indicate acute localized complications resulting from a needle aspiration of the pleural space. Choice D rationale Jugular vein distention indicates elevated right atrial pressure, commonly seen in fluid overload or cardiac tamponade. It is not an expected acute assessment finding associated with localized pulmonary complications of a thoracentesis.
