A nurse is caring for a client who has a chest tube and drainage system in place. The nurse observes that the client’s chest tube was accidentally removed. Which of the following actions should the nurse take first?
Place the tubing in sterile water to restore the water seal.
Apply sterile gauze to the insertion site.
Place tape around the insertion site.
Assess the client’s respiratory status.
The Correct Answer is D
When a chest tube is accidentally removed, the nurse’s first priority is to assess the client’s respiratory status. This determines whether the patient is experiencing respiratory distress, decreased oxygenation, or signs of a pneumothorax. Immediate assessment ensures that life-threatening complications are identified and addressed without delay.
Rationale for Correct Answer
4. Assess the client’s respiratory status: The nurse must first quickly evaluate the client’s airway, breathing, and circulation (ABCs). Assessing respiratory effort, oxygen saturation, breath sounds, and chest expansion helps determine the severity of the situation. Findings guide the urgency and type of intervention required, such as sealing the site or notifying the provider for reinsertion.
Rationale for Incorrect Answers
1. Place the tubing in sterile water to restore the water seal: This action is appropriate only if the chest tube becomes disconnected from the drainage system, not if it is removed from the client’s chest. Re-immersing the tubing in water after removal would not help because the open insertion site, not the tubing, is the concern.
2. Apply sterile gauze to the insertion site: After assessing the client, the nurse should cover the site with a sterile occlusive or petroleum gauze to prevent air entry into the pleural space, which can cause a pneumothorax. However, this comes after assessing the client’s respiratory condition.
3. Place tape around the insertion site: Taping all four sides of the dressing can trap air inside the pleural space, leading to a tension pneumothorax. The dressing should be taped on only three sides if air leakage is suspected, allowing trapped air to escape while preventing more air from entering.
Take-Home Points
- First action: Assess the client’s respiratory status to determine the impact of tube removal.
- If the tube is completely removed, apply a sterile occlusive or petroleum gauze dressing to the site.
- Do not tape all four sides—leave one side open if air is suspected to escape.
- Placing the tubing in water is only appropriate for system disconnections, not accidental removals.

Correct Answer is D
Explanation
When assisting with chest tube removal, the nurse should instruct the client to perform the Valsalva maneuver. This involves taking a deep breath, holding it, and bearing down as if exhaling forcefully with a closed airway. The maneuver increases intrathoracic pressure, preventing air from entering the pleural space during tube removal and reducing the risk of pneumothorax.
Rationale for Correct Answer
4. Perform the Valsalva maneuver: The Valsalva maneuver temporarily increases intrathoracic pressure, which helps seal the pleural space as the tube is withdrawn. This technique prevents air from being sucked into the chest cavity and supports lung re-expansion. The nurse should also ensure that a sterile occlusive dressing is immediately applied to the site after removal to maintain a closed system.
Rationale for Incorrect Answers
1. Lie on his left side: Positioning on a particular side is not necessary during chest tube removal. The client is typically positioned in a semi-Fowler’s or supine position to allow comfort and easy access to the insertion site.
2. Use the incentive spirometer: Incentive spirometry is useful for promoting lung expansion after the procedure, not during removal. It should be resumed once the site is sealed and stable to prevent atelectasis.
3. Cough at regular intervals: Coughing during removal could force air into the pleural space through the open site, increasing the risk of pneumothorax. Controlled breath-holding or the Valsalva maneuver is safer and more effective.
Take-Home Points
- Instruct the client to perform the Valsalva maneuver during chest tube removal to prevent air entry into the pleural space.
- Immediately apply a sterile occlusive dressing after tube removal to maintain a closed seal.
- The semi-Fowler’s position is ideal for comfort and accessibility during removal.
- Incentive spirometry should be used after the procedure to promote lung expansion.
Correct Answer is B
Explanation
Following placement of a chest tube connected to a wet-suction drainage system, certain observations indicate normal function (such as gentle suction-chamber bubbling and a secure occlusive dressing), while others require immediate correction to prevent impaired drainage and respiratory compromise. A dependent loop hanging off the edge of the bed allows fluid to collect and obstruct flow, so it requires immediate intervention to restore proper, gravity-assisted drainage.
Rationale for Correct Answer
2. Dependent loop hanging off the edge of the bed: Dependent loops permit fluid to pool, creating a site of obstruction and increasing the risk of impaired drainage, backflow, and possible tension physiology. The tubing should run straight, without kinks or dependent loops, and remain below chest level to ensure continuous gravity drainage.
Rationale for Incorrect Answers
1. Bubbling in the suction chamber: Gentle, continuous bubbling in the suction control chamber is an expected finding in a wet-suction system and indicates the suction source is functioning. Only excessive or violent bubbling would prompt further assessment for excessive suction or evaporation.
3. Banded connections between tubing sections: Secured (taped or banded) connections are appropriate and help maintain an airtight system, preventing air leaks.
4. Occlusive dressing over chest tube insertion site: An occlusive dressing at the insertion site is correct practice to prevent air entry and infection; it does not require intervention.
Take-Home Points
- Dependent loops in drainage tubing must be eliminated immediately to prevent obstruction and backflow.
- Keep the drainage tubing straight, below chest level, and free of kinks or dependent areas.
- Gentle bubbling in the suction chamber and a secure occlusive dressing are expected, appropriate findings.
- Secure connections (taped/banded) help prevent air leaks and maintain system integrity.
