Ch 21 Respiratory Care Modalities (Chest Tubes), Nursing 403 Chapter 21 Nclex questions (Chest tubes)
After lobectomy for lung cancer, a client receives a chest tube connected to a disposable chest drainage system. The nurse observes that the drainage system is functioning correctly when she notes tidal movements or fluctuations in which compartment of the system as the client breathes? a) Collection chamber b) Water-seal chamber c) Air-leak chamber d) Suction control chamber
Water-seal chamber Fluctuations in the water-seal compartment are called tidal movements and indicate normal function of the system as the pressure in the tubing changes with the client's respirations. The air-leak meter — not chamber — detects air leaking from the pleural space. The collection chamber connects the chest tube from the client to the system. Drainage from the tube drains into and collects in a series of calibrated columns in this chamber. The suction control chamber provides the suction, which can be controlled to provide negative pressure to the chest. (less)
After undergoing a left thoracotomy, a client has a chest tube in place. When caring for this client, the nurse must: a) report fluctuations in the water-seal chamber. b) milk the chest tube every 2 hours. c) clamp the chest tube once every shift. d) encourage coughing and deep breathing.
encourage coughing and deep breathing. When caring for a client who's recovering from a thoracotomy, the nurse should encourage coughing and deep breathing to prevent pneumonia. Fluctuations in the water-seal chamber are normal. Clamping the chest tube could cause a tension pneumothorax. Chest tube milking is controversial and should be done only to remove blood clots that obstruct the flow of drainage.
The nurse is preparing to assist the health care provider with the removal of a patient's chest tube. Which of the following instructions will the nurse correctly give the patient? a) "Exhale forcefully while the chest tube is being removed." b) "While the chest tube is being removed, raise your arms above your head." c) "During the removal of the chest tube, do not move because it will make the removal more painful." d) "When the tube is being removed, take a deep breath, exhale, and bear down."
"When the tube is being removed, take a deep breath, exhale, and bear down." When assisting in the chest tube's removal, instruct the patient to perform a gentle Valsalva maneuver or to breathe quietly. The chest tube is then clamped and quickly removed. Simultaneously, a small bandage is applied and made airtight with petrolatum gauze covered by a 4 × 4-inch gauze pad and thoroughly covered and sealed with nonporous tape. The other options are incorrect instructions for the patient.
A patient is exhibiting signs of a pneumothorax following tracheostomy. The surgeon inserts a chest tube into the anterior chest wall. What should the nurse tell the family is the primary purpose of this chest tube? A) To remove air from the pleural space B) To drain copious sputum secretions C) To monitor bleeding around the lungs D) To assist with mechanical ventilation
Ans: A Feedback: Chest tubes and closed drainage systems are used to re-expand the lung involved and to remove excess air, fluid, and blood. The primary purpose of a chest tube is not to drain sputum secretions, monitor bleeding, or assist with mechanical ventilation.
The OR nurse is setting up a water-seal chest drainage system for a patient who has just had a thoracotomy. The nurse knows that the amount of suction in the system is determined by the water level. At what suction level should the nurse set the system? A) 20 cm H2O B) 15 cm H2O C) 10 cm H2O D) 5 cm H2O
Ans: A Feedback: The amount of suction is determined by the water level. It is usually set at 20 cm H2O; adding more fluid results in more suction.
A nurse educator is reviewing the indications for chest drainage systems with a group of medical nurses. What indications should the nurses identify? Select all that apply. A) Post thoracotomy B) Spontaneous pneumothorax C) Need for postural drainage D) Chest trauma resulting in pneumothorax E) Pleurisy
Ans: A, B, D Feedback: Chest drainage systems are used in treatment of spontaneous pneumothorax and trauma resulting in pneumothorax. Postural drainage and pleurisy are not criteria for use of a chest drainage system.
While assessing the patient, the nurse observes constant bubbling in the water-seal chamber of the patients closed chest-drainage system. What should the nurse conclude? A) The system is functioning normally. B) The patient has a pneumothorax. C) The system has an air leak. D) The chest tube is obstructed.
Ans: C Feedback: Constant bubbling in the chamber often indicates an air leak and requires immediate assessment and intervention. The patient with a pneumothorax will have intermittent bubbling in the water-seal chamber. If the tube is obstructed, the nurse should notice that the fluid has stopped fluctuating in the water-seal chamber.
A nurse is educating a patient in anticipation of a procedure that will require a water-sealed chest drainage system. What should the nurse tell the patient and the family that this drainage system is used for? A) Maintaining positive chest-wall pressure B) Monitoring pleural fluid osmolarity C) Providing positive intrathoracic pressure D) Removing excess air and fluid
Ans: D Feedback: Chest tubes and closed drainage systems are used to re-expand the lung involved and to remove excess air, fluid, and blood. They are not used to maintain positive chest-wall pressure, monitor pleural fluid, or provide positive intrathoracic pressure.
The nurse is assessing a patient who has a chest tube in place for the treatment of a pneumothorax. The nurse observes that the water level in the water seal rises and falls in rhythm with the patients respirations. How should the nurse best respond to this assessment finding? A) Gently reinsert the chest tube 1 to 2 cm and observe if the water level stabilizes. B) Inform the physician promptly that there is in imminent leak in the drainage system. C) Encourage the patient to do deep breathing and coughing exercises. D) Document that the chest drainage system is operating as it is intended.
Ans: D Feedback: Fluctuation of the water level in the water seal shows effective connection between the pleural cavity and the drainage chamber and indicates that the drainage system remains patent. No further action is needed.
The nurse is caring for a patient following a thoracotomy. Which of the following findings requires immediate intervention by the nurse? a) Heart rate: 112 bpm b) Chest tube drainage of 190 mL/hr c) Moderate amounts of colorless sputum d) Pain of 5 on a 1 to 10 pain scale
Chest tube drainage of 190 mL/hr The nurse should monitor and document the amount and character of drainage every 2 hours. The nurse will notify the primary provider if drainage is 150 mL/hr or greater. The other findings are normal following a thoracotomy; no intervention is required.
The nurse is transporting a patient with chest tubes to a treatment room. The chest tube becomes disconnected and falls between the bed rail. What is the priority action by the nurse? a) Immediately reconnect the chest tube to the drainage apparatus. b) Cut the contaminated tip of the tube and insert a sterile connector and reattach. c) Clamp the chest tube close to the connection site. d) Call the physician.
Cut the contaminated tip of the tube and insert a sterile connector and reattach. If the patient is lying on a stretcher and must be transported to another area, place the drainage system below the chest level. If the tubing disconnects, cut off the contaminated tips of the chest tube and tubing, insert a sterile connector in the cut ends, and reattach to the drainage system. Do not clamp the chest tube during transport. (less)
A client is receiving supplemental oxygen. When determining the effectiveness of oxygen therapy, which arterial blood gas value is most important? a) Partial pressure of arterial oxygen (PaO2) b) Bicarbonate (HCO3-) c) Partial pressure of arterial carbon dioxide (PaCO2) d) pH
Partial pressure of arterial oxygen (PaO2) The most significant and direct indicator of the effectiveness of oxygen therapy is the PaO2 value. Based on the PaO2 value, the nurse may adjust the type of oxygen delivery (cannula, Venturi mask, or mechanical ventilator), flow rate, and oxygen percentage. The other options reflect the client's ventilation status, not oxygenation. The pH, HCO3-, and PaCO2 (less)

The nurse is caring for a patient who is scheduled for a lobectomy. Following the procedure, the nurse will plan care based on which of the following? a) The patient will return from surgery with no drainage tubes. b) The patient will require mechanical ventilation following surgery. c) The patient will return to the nursing unit with two chest tubes. d) The patient will require sedation until the chest tube (s) are removed.
The patient will return to the nursing unit with two chest tubes. The nurse should plan for the patient to return to the nursing unit with two chest tubes intact. During a lobectomy, the lobe is removed, and the remaining lobes of the lung are re-expanded. Usually, two chest catheters are inserted for drainage. The upper tube is for air removal; the lower one is for fluid drainage. Sometimes, only one catheter is needed. The chest tube is connected to a chest drainage apparatus for several days.
A nurse observes constant bubbling in the water-seal chamber of a closed chest drainage system. What should the nurse conclude? a) The client has a pneumothorax. b) The system has an air leak. c) The chest tube is obstructed. d) The system is functioning normally.
The system has an air leak. Constant bubbling in the water-seal chamber indicates an air leak and requires immediate intervention. The client with a pneumothorax will have intermittent bubbling in the water-seal chamber. Clients without a pneumothorax should have no evidence of bubbling in the chamber. If the tube is obstructed, the fluid would stop fluctuating in the water-seal chamber. (less)
After lobectomy for lung cancer, a client receives a chest tube connected to a disposable chest drainage system. The nurse observes that the drainage system is functioning correctly when she notes tidal movements or fluctuations in which compartment of the system as the client breathes? a) Collection chamber b) Air-leak chamber c) Suction control chamber d) Water-seal chamber
Water-seal chamber Fluctuations in the water-seal compartment are called tidal movements and indicate normal function of the system as the pressure in the tubing changes with the client's respirations. The air-leak meter — not chamber — detects air leaking from the pleural space. The collection chamber connects the chest tube from the client to the system. Drainage from the tube drains into and collects in a series of calibrated columns in this chamber. The suction control chamber provides the suction, which can be controlled to provide negative pressure to the chest. (less)
A client is recovering from thoracic surgery needed to perform a right lower lobectomy. Which of the following is the most likely postoperative nursing intervention? a) Make sure that a thoracotomy tube is linked to open chest drainage. b) Restrict intravenous fluids for at least 24 hours. c) Assist with positioning the client on the right side. d) Encourage coughing to mobilize secretions.
Encourage coughing to mobilize secretions. The client is encouraged to cough frequently to mobilize secretions. The client will be placed in the semi-Fowler's position. Thoracotomy tubes are always attached to closed, sealed drainage to re-expand lung tissue and prevent pneumothorax. Restricting IV fluids in a client who is NPO while recovering from surgery would lead to dehydration. (less)
