Chapter 28: Supporting Ventilation Flashcards
Chest Tubes
The nurse is reviewing the function of chest tubes with a group of students. Which statement indicates a correct understanding of their purpose?
A. “Chest tubes are inserted to create positive pressure in the pleural space.”
B. “Chest tubes are used to re-establish negative pressure in the pleural space.”
C. “The goal of chest tubes is to increase the amount of air in the pleural space.”
D. “Chest tubes prevent fluid accumulation in the alveoli.”
B. “Chest tubes are used to re-establish negative pressure in the pleural space.”
Rationale: The pleural space normally has a negative pressure that allows the lungs to stay inflated. A chest tube re-establishes this negative pressure by draining air or fluid, promoting lung expansion.
Which clinical scenario requires the insertion of a large (36F to 40F) chest tube?
A. Spontaneous pneumothorax
B. Hemothorax
C. Pleural effusion
D. Tension pneumothorax
B. Hemothorax
Rationale: Large chest tubes (36F to 40F) are used to drain blood from the pleural space, as seen in a hemothorax. Smaller tubes (12F to 24F) are sufficient for air drainage, and medium tubes (24F to 36F) are often used for fluid drainage in conditions like pleural effusion.
A nurse notices continuous bubbling in the water-seal chamber of a patient’s chest tube drainage system. What is the most appropriate initial action by the nurse?
A. Check for air leaks in the system.
B. Increase the suction pressure.
C. Clamp the chest tube.
D. Notify the provider immediately.
A. Check for air leaks in the system.
Rationale: Continuous bubbling in the water-seal chamber may indicate an air leak. The nurse should first check the system for leaks. Clamping the tube or increasing suction pressure is not appropriate as initial actions. The provider should be notified only if the issue cannot be resolved.
A patient undergoing chest tube insertion is given a local anesthetic. Which area is most likely to be anesthetized for the procedure?
A. The lower abdomen
B. The diaphragm
C. The intercostal muscles at the insertion site
D. The chest wall at the insertion site
D. The chest wall at the insertion site
Rationale: The local anesthetic is injected into the chest wall at the insertion site to numb the area where the incision is made, ensuring the patient remains comfortable during the procedure.
The nurse is preparing a patient for chest tube insertion. What is the primary purpose of elevating the patient’s head to 45 degrees during the procedure?
A. To reduce the risk of aspiration
B. To improve lung expansion
C. To lower the diaphragm and reduce the risk of injury
D. To increase the patient’s comfort during the procedure
C. To lower the diaphragm and reduce the risk of injury
Rationale: Elevating the head of the bed up to 45 degrees lowers the diaphragm, which reduces the risk of injury to the diaphragm during chest tube insertion.
What is the most appropriate action if a chest tube is inserted at the bedside, but the healthcare provider is unable to confirm tube placement immediately?
A. Continue with the procedure and wait for the patient to stabilize
B. Perform a chest x-ray to confirm the chest tube placement
C. Reassure the patient and monitor vital signs
D. Withdraw the chest tube and insert a new one immediately
B. Perform a chest x-ray to confirm the chest tube placement
Rationale: Tube placement is confirmed by a chest x-ray after insertion to ensure it is in the correct location and functioning properly.
After a chest tube is inserted, the healthcare provider sutures the tube in place and covers the wound with an occlusive dressing. What is the rationale for using petroleum gauze around the chest tube insertion site?
A. To create an airtight seal
B. To prevent infection
C. To minimize pain during the procedure
D. To allow drainage of any residual air or fluid
A. To create an airtight seal
Rationale: Petroleum gauze is used to seal the wound around the chest tube to create an airtight seal, preventing air from entering the pleural space and ensuring proper chest tube function.
During chest tube insertion, why does the healthcare provider insert the tube up and over the top of the rib rather than below the rib?
A. To avoid damaging the intercostal nerves and blood vessels
B. To ensure easier drainage of blood from the pleural space
C. To reduce the risk of puncturing the lung
D. To prevent damage to the diaphragm
A. To avoid damaging the intercostal nerves and blood vessels
Rationale: The chest tube is advanced up and over the top of the rib to avoid the intercostal nerves and blood vessels that lie behind the rib inferiorly.
A nurse is assisting with the insertion of a chest tube for a patient with a pneumothorax. Which position should the nurse place the patient in for the procedure?
A. Supine with the affected arm at the side
B. Prone with the head elevated
C. Sitting upright with the head tilted forward
D. Lying on the unaffected side with the arm raised above the head
D. Lying on the unaffected side with the arm raised above the head
Rationale: The patient is positioned with the arm raised above the head on the affected side to expose the midaxillary area, which is the standard site for chest tube insertion.
A nurse is caring for a patient with a chest tube after surgery. The patient has 250 mL of drainage in the first hour. What should the nurse do?
A. Continue to monitor the drainage as normal.
B. Notify the healthcare provider (HCP) immediately.
C. Increase the suction pressure on the drainage system.
D. Administer a diuretic to reduce the drainage amount.
B. Notify the healthcare provider (HCP) immediately.
Rationale: Rationale: The nurse should notify the HCP if drainage exceeds 200 mL in the first hour, as this may indicate excessive fluid or blood removal that can lead to complications, including re-expansion pulmonary edema or severe hypotension.
What is the priority nursing action if a chest tube becomes disconnected from the drainage system?
A. Immerse the exposed end of the chest tube in sterile water.
B. Clamp the chest tube immediately to prevent air from entering.
C. Replace the chest drainage system right away.
D. Apply a sterile dressing to the chest tube insertion site.
A. Immerse the exposed end of the chest tube in sterile water.
Rationale: If the chest tube becomes disconnected, the immediate priority is to re-establish the water-seal system. The exposed end of the tube should be immersed in sterile water until a new drainage system is set up to prevent a tension pneumothorax.
A nurse palpates a “crackling” sensation around the chest tube insertion site. What does this indicate?
A. Subcutaneous emphysema.
B. Infection at the insertion site.
C. Air leak in the drainage system.
D. Accumulation of blood in the pleural space.
A. Subcutaneous emphysema.
Rationale: The “crackling” sensation is indicative of subcutaneous emphysema, which occurs when air leaks into the tissue around the chest tube insertion site. A small amount of subcutaneous air is typically harmless, but significant emphysema around the neck or face can cause airway compromise.
What is the most appropriate nursing intervention to reduce the risk of atelectasis and shoulder stiffness in a patient with a chest tube?
A. Encourage the patient to lie flat and rest.
B. Encourage coughing, deep breathing, and range-of-motion exercises.
C. Restrict the patient from moving their affected arm.
D. Use a heating pad over the shoulder area.
B. Encourage coughing, deep breathing, and range-of-motion exercises.
Rationale: To prevent atelectasis and shoulder stiffness, the nurse should encourage the patient to engage in coughing, deep breathing, and use an incentive spirometer. Range-of-motion exercises also help to reduce shoulder stiffness.
A nurse is assessing a patient with a chest tube and notices new intermittent bubbling in the water-seal chamber. What is the nurse’s priority action?
A. Increase the suction pressure to −40 cm H2O.
B. Clamp the chest tube immediately to stop the bubbling.
C. Assess the drainage system for an air leak.
D. Notify the healthcare provider about the bubbling.
C. Assess the drainage system for an air leak.
Rationale: New intermittent bubbling in the water-seal chamber can indicate an air leak. The nurse should assess the drainage system to determine whether the leak is coming from the patient or the system itself.
What is the primary concern if a large amount of fluid (1 to 1.5 L) is removed rapidly from the pleural space after chest tube insertion?
A. Hypovolemic shock due to rapid blood loss.
B. Severe pain and discomfort in the chest.
C. Air embolism causing respiratory arrest.
D. Re-expansion pulmonary edema or severe hypotension.
D. Re-expansion pulmonary edema or severe hypotension.
Rationale: Rapid removal of large amounts of fluid can lead to re-expansion pulmonary edema or severe symptomatic hypotension. This can occur due to the rapid re-expansion of the lung and changes in intrathoracic pressure.
A nurse is caring for a patient with a chest tube. When is it appropriate to clamp the chest tube momentarily?
A. To assess for subcutaneous emphysema.
B. When disconnecting the drainage system for transport.
C. To check for air leaks or change the drainage apparatus.
D. To prevent an air leak during coughing.
C. To check for air leaks or change the drainage apparatus.
Rationale: The chest tube can be momentarily clamped to assess for air leaks or to change the drainage apparatus. However, clamping should be done according to agency policy, and the tube should never be clamped for extended periods due to the risk of tension pneumothorax.
A nurse is caring for a patient with a chest tube attached to a drainage system. The nurse observes intermittent bubbling in the water-seal chamber. What is the most likely explanation for this finding?
A. The chest tube is obstructed.
B. The air leak in the pleural space is resolving.
C. The patient is developing a tension pneumothorax.
D. The suction control chamber is malfunctioning.
B. The air leak in the pleural space is resolving.
Rationale: Intermittent bubbling in the water-seal chamber can occur during exhalation, coughing, or sneezing as intrathoracic pressure changes. This is common as the air leak in the pleural space resolves, and the lung becomes more fully expanded.
What does the term “tidaling” in the water-seal chamber of a chest drainage system indicate?
A. A blockage in the chest tube
B. Increased air leak from the pleural space
C. Malfunctioning of the suction control chamber
D. Normal movement of water with the patient’s breathing
D. Normal movement of water with the patient’s breathing
Rationale: Tidaling refers to the normal up and down movement of water in the water-seal chamber that reflects changes in intrapleural pressure during inspiration and expiration.
A nurse notices that tidaling has stopped suddenly in the water-seal chamber of a patient’s chest drainage system. What is the most appropriate action for the nurse to take?
A. Increase the suction pressure.
B. Continue to monitor the patient’s condition.
C. Assess the chest tube for occlusion.
D. Notify the provider immediately.
C. Assess the chest tube for occlusion.
Rationale: A sudden stop in tidaling may indicate that the chest tube is occluded. The nurse should assess the tube to determine if there is a blockage or issue with the drainage.
In a water suction chest drainage system, how is the amount of suction applied to the pleural space determined?
A. By the dial on the chest drainage unit
B. By the height of the water-seal chamber
C. By the size of the chest tube used
D. By the amount of water in the suction control chamber
D. By the amount of water in the suction control chamber
Rationale: In a wet suction system, the amount of suction applied is determined by the amount of water in the suction control chamber. The water column controls the level of suction.
A nurse is caring for a patient with a dry suction chest drainage system. Which of the following should the nurse assess to ensure the system is functioning properly?
A. The amount of water in the suction control chamber
B. The dial setting on the chest drainage unit
C. The water fluctuation in the water-seal chamber
D. The patient’s respiratory rate
B. The dial setting on the chest drainage unit
Rationale: In a dry suction system, the suction level is set by adjusting the dial on the chest drainage unit, not by the amount of water.
A patient with a chest tube has a flutter valve in place. Which of the following is a benefit of using a flutter valve for pneumothorax management?
A. It allows for patient mobility.
B. It prevents all fluid drainage from the pleural space.
C. It provides continuous suction.
D. It prevents air from entering the pleural space during inspiration.
A. It allows for patient mobility.
Rationale: The flutter valve allows for mobility because it is small, enabling the patient to move around with minimal disruption. It prevents air from re-entering the pleural space during inspiration and allows air to vent during expiration.
