NCLEX Questions for Respiratory System Questions
Question 1 of 5
The organs of the respiratory system include all the following EXCEPT:
Correct Answer: D
Rationale: The correct answer is D: body tissues. The respiratory system is responsible for breathing and exchanging gases, involving organs like the nose, trachea, and lungs. Body tissues, on the other hand, are not specific organs exclusively dedicated to respiration. They may play a role in gas exchange, but they are not organs of the respiratory system. Therefore, the correct answer is D. Choices A, B, and C are incorrect because the nose, trachea, and lungs are all integral parts of the respiratory system involved in the process of breathing and gas exchange.
Question 2 of 5
A male client is asking the nurse a question regarding the Mantoux test for tuberculosis. The nurse should base her response on the fact that the:
Correct Answer: B
Rationale: The correct answer is B. The Mantoux test for tuberculosis is a skin test that detects the presence of the tuberculosis bacteria in the body. It does not differentiate between active and dormant infection because it only measures the immune response to the infection. The presence of a wheal or area of redness at the injection site is a normal response to the test and does not indicate active tuberculosis. Measuring the area of redness in 3 days or requiring a second test in 3 months are not accurate statements about the Mantoux test. Therefore, the best response is B as it aligns with the purpose and limitations of the Mantoux test.
Question 3 of 5
A client diagnosed with pleurisy is being started on medication therapy with a nonsteroidal anti-inflammatory drug. A nurse teaches the client that this medication?
Correct Answer: D
Rationale: The correct answer is D because nonsteroidal anti-inflammatory drugs (NSAIDs) help relieve pain by reducing inflammation, which can improve breathing and coughing for a client with pleurisy. NSAIDs do not act as mild narcotic analgesics (B) or glucocorticoids (C). While NSAIDs may alleviate surface pain (A), their primary mechanism is reducing inflammation to relieve pain and improve respiratory function.
Question 4 of 5
A persistent, productive cough with bloody sputum (hemoptysis) is a common symptom of:
Correct Answer: D
Rationale: The correct answer is D: Tuberculosis. Hemoptysis is a hallmark symptom of tuberculosis due to the erosion of blood vessels in the lungs by the Mycobacterium tuberculosis bacteria. The persistent cough in tuberculosis is often productive and accompanied by bloody sputum. Emphysema (A) is characterized by shortness of breath and wheezing, not hemoptysis. Cystic fibrosis (B) presents with thick mucus production, not bloody sputum. Sinusitis (C) typically causes nasal congestion and facial pain, not hemoptysis.
Question 5 of 5
The amount of air that moves into and out of the human lungs in each normal breath is termed
Correct Answer: C
Rationale: The correct answer is C: tidal volume. Tidal volume is the amount of air moved into and out of the lungs during normal breathing. It represents the normal, resting breathing pattern. Inspirational capacity (A) is the maximum amount of air the lungs can hold after a maximum inhalation. Reserve volume (B) is the additional air that can be forcefully exhaled after a normal exhalation. Alveolar volume (D) refers to the amount of air in the alveoli available for gas exchange. Tidal volume best represents the amount of air exchanged during normal breathing.
