Nokea
The nurse is caring for a patient who has a steering wheel injury as a result of an automobile accident. Which of the following findings should be of most concern to the nurse during the initial assessment?
- A. Paradoxical chest movement
- B. The complaint of chest wall pain
- C. A heart rate of 110 beats/minute
- D. A large bruised area on the chest
Correct Answer: A
Rationale: Paradoxical chest movement indicates that the patient may have flail chest, which can severely compromise gas exchange and can rapidly lead to hypoxemia. Chest wall pain, a slightly elevated pulse rate, and chest bruising all require further assessment or intervention, but the priority concern is poor gas exchange.

The nurse is caring for a patient with stage I non-small cell lung cancer who is scheduled for a lobectomy. The patient tells the nurse, 'I would rather have radiation than surgery.' Which of the following responses by the nurse is best?
- A. Are you afraid that the surgery will be very painful?
- B. Did you have bad experiences with previous surgeries?
- C. Surgery is the treatment of choice for stage I lung cancer.
- D. Tell me what you know about the various treatments available.
Correct Answer: D
Rationale: More assessment of the patient's concerns about surgery is indicated. An open-ended response will elicit the most information from the patient. The answer beginning, 'Surgery is the treatment of choice' is accurate, but it discourages the patient from sharing concerns about surgery. The remaining two answers indicate that the nurse has jumped to conclusions about the patient's reasons for not wanting surgery.
The nurse is caring for a patient with primary pulmonary hypertension (PPH) who is receiving nifedipine. Which of the following findings indicate that the treatment is effective?
- A. BP is less than 140/90 mm Hg
- B. Patient reports decreased exertional dyspnea.
- C. Heart rate is between 60 and 100 beats/minute.
- D. Patient's chest x-ray indicates clear lung fields.
Correct Answer: B
Rationale: Since a major symptom of PPH is exertional dyspnea, an improvement in this symptom would indicate that the medication was effective. Nifedipine will affect BP and heart rate, but these parameters would not be used to monitor effectiveness of therapy for a patient with PPH. The chest x-ray will show clear lung fields even if the therapy is not effective.
The nurse is caring for a patient who has a right-sided chest tube following a thoracotomy and has continuous bubbling in the suction-control chamber of the collection device. Which of the following actions should the nurse implement?
- A. Document the presence of a large air leak.
- B. Obtain and attach a new collection device.
- C. Notify the surgeon of a possible pneumothorax.
- D. Take no further action with the collection device.
Correct Answer: D
Rationale: Continuous bubbling is expected in the suction-control chamber and indicates that the suction-control chamber is connected to suction. An air leak would be detected in the water-seal chamber. There is no evidence of pneumothorax. A new collection device is needed when the collection chamber is filled.
The nurse is caring for a patient who has just had a thoracentesis. Which of the following information is most important to communicate to the health care provider?
- A. BP is 150/90 mm Hg.
- B. Oxygen saturation is 89%.
- C. Pain level is 5/10 with a deep breath.
- D. Respiratory rate is 24 when lying flat.
Correct Answer: B
Rationale: Oxygen saturation would be expected to improve after a thoracentesis. A saturation of 89% indicates that a complication such as pneumothorax may be occurring. The other assessment data also indicate a need for ongoing assessment or intervention, but the low oxygen saturation is the priority.
Which of the following nursing actions is most effective in preventing aspiration pneumonia in patients who are at risk?
- A. Turn and reposition immobile patients at least every 2 hours.
- B. Place patients with altered consciousness in side-lying positions.
- C. Monitor for respiratory symptoms in patients who are immuno-suppressed.
- D. Provide for continuous subglottic aspiration in patients receiving enteral feedings.
Correct Answer: B
Rationale: The risk for aspiration is decreased when patients with a decreased level of consciousness are placed in a side-lying or upright position. Frequent turning prevents pooling of secretions in immobilized patients but will not decrease the risk for aspiration in patients at risk. Monitoring of parameters such as breath sounds and oxygen saturation will help detect pneumonia in immunocompromised patients, but it will not decrease the risk for aspiration. Continuous subglottic suction is recommended for intubated patients but not for all patients receiving enteral feedings.
