A nurse is caring for a client who has a three-chamber chest tube system. Which of the following actions should the nurse take?
Ensure 2 cm (0.8 in) of water is in the water seal chamber.
Check the patency of the tubing every 2 hr.
Keep the drainage system above the level of the client's chest.
Empty the collection chamber every 8 hr.
The Correct Answer is A
A. Ensure 2 cm (0.8 in) of water is in the water seal chamber. This is correct because maintaining the correct water level in the water seal chamber is essential for proper functioning of the chest tube system, as it prevents air from entering the pleural space.
B. Check the patency of the tubing every 2 hr. This is incorrect because continuous monitoring is required, and patency should be ensured at all times, not just at set intervals. However, frequent assessments are important.
C. Keep the drainage system above the level of the client's chest. This is incorrect because the drainage system should be kept below chest level to allow gravity drainage and prevent backflow into the pleural space.
D. Empty the collection chamber every 8 hr. This is incorrect because the collection chamber should only be emptied when full, following facility protocol, to maintain an accurate record of drainage output.

Correct Answer is B
Explanation
A. Schedule the client for an MRI after the procedure. This is incorrect because an MRI is not required following a thoracentesis. Instead, a chest X-ray may be ordered to assess for complications such as a pneumothorax.
B. Place the client leaning forward over the overbed table. This is correct because this position allows for optimal lung expansion and easier access to the pleural space for fluid removal.
C. Encourage the client to take deep breaths during the procedure. This is incorrect because the client should remain still and avoid deep breathing or coughing to prevent lung injury.
D. Ensure the client has been NPO for 6 hr. This is incorrect because NPO status is not required for a thoracentesis, as it is not a gastrointestinal or sedation-based procedure.
Correct Answer is []
Explanation
Potential Condition: Opioid intoxication
Actions to Take:
- Obtain a prescription for naloxone
- Prepare to initiate mechanical ventilation
Parameters to Monitor:
- Pupillary reaction,
- Respiratory rate
Rationale:
- Potential Condition: The client presents with shallow breathing, slurred speech, confusion, pupillary constriction, and bradycardia, which are classic signs of opioid intoxication. The history of back pain also suggests possible opioid use.
- Actions to Take:
- Naloxone is an opioid antagonist that can rapidly reverse respiratory depression caused by opioid overdose.
- Mechanical ventilation may be necessary if respiratory depression is severe and does not improve with naloxone administration.
- Parameters to Monitor:
- Pupillary reaction is important because opioids cause pupillary constriction (miosis). Improvement in pupillary size and reaction indicates the opioid effects are wearing off.
- Respiratory rate should be closely monitored since opioid overdose primarily affects respiratory drive, leading to hypoxia and potential respiratory failure.
