Multiple Choice Questions for Respiratory System Questions
Question 1 of 5
A client has been diagnosed with lung cancer and requires lobectomy. How much of the lung is removed?
Correct Answer: B
Rationale: The correct answer is B: A lobe of the lung. During a lobectomy, a lobe of the lung is surgically removed, typically to treat lung cancer while preserving the remaining lung tissue. Removing one entire lung (choices A and D) is not necessary for a lobectomy and would be a more extensive procedure. Choice C, removing a small localized area near the surface of the lung, does not accurately reflect the extent of tissue removal required for a lobectomy. Therefore, the correct choice is B as it specifically addresses the removal of a lobe during the surgical procedure.
Question 2 of 5
The exchange of gases between blood and cells is called
Correct Answer: B
Rationale: The correct answer is B: internal respiration. This process refers to the exchange of gases between blood and body cells. Pulmonary ventilation (A) is the process of breathing, moving air in and out of the lungs. External respiration (C) is the exchange of gases between the lungs and blood. Cellular respiration (D) is the process where cells use oxygen to produce energy. Internal respiration best describes the exchange of gases at the cellular level.
Question 3 of 5
If the thoracic wall but not lungs is punctured
Correct Answer: B
Rationale: The correct answer is B because if the thoracic wall is punctured but not the lungs, air will enter the pleural cavity causing a pneumothorax. This leads to lung collapse and can result in death due to impaired gas exchange. Choices A and C are incorrect as the lungs do not get inflated and breathing rate does not decrease. Choice D is incorrect as the breathing rate actually increases in response to the decreased lung function.
Question 4 of 5
The greatest quantity of air that can be expired after a maximum inspiratory effort is its
Correct Answer: C
Rationale: The correct answer is C: Vital capacity. Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. Residual volume (A) is the air left in the lungs after maximum exhalation. Tidal volume (B) is the amount of air inhaled and exhaled during normal breathing. Lung volume (D) is a general term and not a specific measure of air quantity. Thus, vital capacity is the best choice as it accounts for the maximum air that can be expired after a deep inhalation.
Question 5 of 5
A nurse plans care for a client who is experiencing dyspnea and must stop multiple times when climbing a flight of stairs. Which intervention would the nurse include in this client's plan of care?
Correct Answer: A
Rationale: The correct answer is A: Assistance with activities of daily living. This intervention helps conserve the client's energy by reducing the physical exertion required for activities like climbing stairs. It promotes independence while ensuring safety and preventing further exacerbation of dyspnea. Physical therapy activities every day (B) may be too strenuous for a client experiencing dyspnea. Oxygen therapy at 2 L per nasal cannula (C) may be necessary for severe cases but does not address the client's functional limitations. Complete bedrest with frequent repositioning (D) may lead to deconditioning and worsen the client's dyspnea.
