Nokea
The nurse is caring for a patient who is scheduled to have a thoracotomy. When planning preoperative teaching, what information should the nurse communicate to the patient?
- A. How to milk the chest tubing
- B. How to splint the incision when coughing
- C. How to take prophylactic antibiotics correctly
- D. How to manage the need for fluid restriction
Correct Answer: B
Rationale: Prior to thoracotomy, the nurse educates the patient about how to splint the incision with the hands, a pillow, or a folded towel. The patient is not taught how to milk the chest tubing because this is performed by the nurse. Prophylactic antibiotics are not normally used and fluid restriction is not indicated following thoracotomy.

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
Correct Answer: D
Rationale: 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 acute medical nurse is preparing to wean a patient from the ventilator. Which assessment parameter is most important for the nurse to assess?
- A. Fluid intake for the last 24 hours
- B. Baseline arterial blood gas (ABG) levels
- C. Prior outcomes of weaning
- D. Electrocardiogram (ECG) results
Correct Answer: B
Rationale: Before weaning a patient from mechanical ventilation, it is most important to have baseline ABG levels. During the weaning process, ABG levels will be checked to assess how the patient is tolerating the procedure. Other assessment parameters are relevant, but less critical. Measuring fluid volume intake and output is always important when a patient is being mechanically ventilated. Prior attempts at weaning and ECG results are documented on the patients record, and the nurse can refer to them before the weaning process begins.
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
Correct Answer: C
Rationale: 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.
The nurse has explained to the patient that after his thoracotomy, it will be important to adhere to a coughing schedule. The patient is concerned about being in too much pain to be able to cough. What would be an alternative nursing intervention for this client?
- A. Teach him postural drainage
- B. Teach him how to perform huffing
- C. Teach him to use a mini-nebulizer
- D. Teach him how to use a metered dose inhaler
Correct Answer: B
Rationale: The technique of huffing may be helpful for the patient with diminished expiratory flow rates or for the patient who refuses to cough because of severe pain. Huffing is the expulsion of air through an open glottis. Inhalers, nebulizers, and postural drainage are not substitutes for performing coughing exercises.
The nurse is discussing activity management with a patient who is postoperative following thoracotomy. What instructions should the nurse give to the patient regarding activity immediately following discharge?
- A. Walk 1 mile 3 to 4 times a week
- B. Use weights daily to increase arm strength
- C. Walk on a treadmill 30 minutes daily
- D. Perform shoulder exercises five times daily
Correct Answer: D
Rationale: The nurse emphasizes the importance of progressively increased activity. The nurse also instructs the patient on the importance of performing shoulder exercises five times daily. The patient should ambulate with limits and realize that the return of strength will likely be gradual and likely will not include weight lifting or lengthy walks.
