Questions for the Respiratory System Questions
Question 1 of 5
Lungs have a large number of narrow tubes called
Correct Answer: B
Rationale: The correct answer is B: Bronchioles. Bronchioles are small, narrow tubes in the lungs that branch off from the bronchi. They play a crucial role in conducting air to the alveoli for gas exchange. Alveoli (choice A) are tiny air sacs at the end of bronchioles where gas exchange occurs, not narrow tubes. Bronchi (choice C) are larger air passages that branch off from the trachea, leading to the bronchioles. Alveolar ducts (choice D) are tiny ducts that connect bronchioles to alveolar sacs, but they are not the large number of narrow tubes found in the lungs. Therefore, the correct answer is bronchioles as they specifically fit the description of narrow tubes in the lungs.
Question 2 of 5
A client is in the family practice clinic reporting a severe cold that started 4 days ago. On examination the nurse notes that the client also has a severe headache and muscle aches. What action by the nurse is best?
Correct Answer: D
Rationale: The correct answer is D: Teach the client to sneeze in the upper sleeve. This action is best because the client is showing symptoms of a cold, which is typically caused by a virus spread through respiratory droplets. Instructing the client to sneeze in the upper sleeve can help prevent the spread of the virus to others. Choice A is incorrect because oseltamivir is used to treat influenza, not the common cold. Choice B is unnecessary as hospital admission is not typically warranted for a cold. Choice C is also incorrect as the client is already sick and a flu vaccine would not be effective at this point in time.
Question 3 of 5
In general, when looking at acid-base balance, how does the body compensate with metabolic acidosis?
Correct Answer: A
Rationale: The correct answer is A. In metabolic acidosis, the lungs compensate by increasing respiratory rate and depth ('blowing off' CO2) to reduce acidity and raise pH. B is incorrect because retaining CO2 would worsen acidosis. C is partially true long-term but slower acting than pulmonary compensation. D is incorrect because excreting bicarbonate lowers pH further.
Question 4 of 5
The nursing assistant tells you that the client on oxygen at a flow rate of 6 L/min by nasal cannula is complaining of nasal passage discomfort. What intervention should you suggest to improve the client's comfort for this problem?
Correct Answer: A
Rationale: The correct answer is A. Humidifying oxygen reduces nasal dryness and irritation caused by high-flow oxygen through a nasal cannula. Using a face mask (B) might help but is less practical for long-term use. Providing an extra pillow (C) or sitting up in a chair (D) does not address the nasal discomfort directly.
