Chapter 20 : Assessment of Respiratory Function Questions
Question 1 of 5
The nurse is caring for a patient who has just undergone a mediastinotomy. What should be the focus of the nurses postprocedure care?
Correct Answer: B
Rationale: Chest tube drainage is required after mediastinotomy. PFT, chest physiotherapy, and oral suctioning would all be contraindicated because of the patients unstable health status.
Question 2 of 5
The nurse is caring for a patient who has a pleural effusion and who underwent a thoracoscopic procedure earlier in the morning. The nurse should prioritize assessment for which of the following?
Correct Answer: B
Rationale: Follow-up care in the health care facility and at home involves monitoring the patient for shortness of breath (which might indicate a pneumothorax). All of the listed options are relevant assessment findings, but shortness of breath is the most serious complication.
Question 3 of 5
A gerontologic nurse is analyzing the data from a patients focused respiratory assessment. The nurse is aware that the amount of respiratory dead space increases with age. What is the effect of this physiological change?
Correct Answer: B
Rationale: The amount of respiratory dead space increases with age. Combined with other changes, this results in a decreased diffusion capacity for oxygen with increasing age, producing lower oxygen levels in the arterial circulation. Decreased shunting and increased ventilation do not occur with age.
Question 4 of 5
The nurse is assessing the respiratory status of a patient who is experiencing an exacerbation of her emphysema symptoms. When preparing to auscultate, what breath sounds should the nurse anticipate?
Correct Answer: C
Rationale: The breath sounds of the patient with emphysema are faint or often completely inaudible. When they are heard, the expiratory phase is prolonged.
Question 5 of 5
The patient has just had an MRI ordered because a routine chest x-ray showed suspicious areas in the right lung. The physician suspects bronchogenic carcinoma. An MRI would most likely be ordered to assess for what in this patient?
Correct Answer: D
Rationale: MRI is used to characterize pulmonary nodules; to help stage bronchogenic carcinoma (assessment of chest wall invasion); and to evaluate inflammatory activity in interstitial lung disease, acute pulmonary embolism, and chronic thrombolytic pulmonary hypertension. Imaging would not focus on the alveoli since the problem is in the bronchi. A static image such as MRI cannot inform PFT.
