NCLEX Questions for Respiratory System Questions
Question 1 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.
Question 2 of 5
Adam's Apple corresponds to
Correct Answer: C
Rationale: The Adam's Apple corresponds to the larynx. The larynx houses the vocal cords and plays a key role in producing sound. The prominent cartilage in the front of the larynx is what forms the Adam's Apple. The epiglottis (A) covers the trachea during swallowing to prevent food from entering the airway. The trachea (B) is the windpipe that carries air to and from the lungs. The thyroid (D) is a gland located in the neck that produces hormones regulating metabolism. Therefore, the correct answer is C as it directly relates to the anatomical structure of the Adam's Apple.
Question 3 of 5
Which of the following prevents collapsing of trachea
Correct Answer: D
Rationale: The correct answer is D: Cartilaginous rings. Cartilaginous rings in the trachea provide structural support and prevent collapsing of the trachea during breathing. They maintain the shape of the trachea, ensuring that air can flow freely into the lungs. Muscles (choice A) are not directly responsible for preventing tracheal collapse. While the diaphragm (choice B) plays a crucial role in breathing, it does not specifically prevent tracheal collapse. Ribs (choice C) protect the thoracic organs but do not have a direct role in preventing tracheal collapse.
Question 4 of 5
A nurse is caring for a client who received benzocaine spray prior to a recent bronchoscopy. The client presents with continuous cyanosis even with oxygen therapy. What action would the nurse take next?
Correct Answer: B
Rationale: The correct answer is B: Notify the Rapid Response Team. The client's continuous cyanosis despite oxygen therapy indicates a serious respiratory distress requiring immediate intervention. The Rapid Response Team is equipped to assess and manage such critical situations promptly. Administering albuterol (A) is not appropriate without further assessment. Assessing peripheral pulses (C) may not address the underlying cause of cyanosis. Obtaining blood and sputum cultures (D) is important for infection control but not the priority in this acute situation.
Question 5 of 5
A nurse cares for a client after radiation therapy for neck cancer. The client reports extreme dry mouth. What action by the nurse is most appropriate?
Correct Answer: C
Rationale: The correct answer is C. The nurse should explain that xerostomia (dry mouth) may be a permanent side effect of radiation therapy for neck cancer. This is the most appropriate action as it educates the client about the potential long-term effects of the treatment. Option A is incorrect as lidocaine mouthwash may not address the underlying issue of dry mouth. Option B is incorrect as administering IV fluid boluses every 2 hours is not indicated for dry mouth. Option D is incorrect as assessing the client's neck for redness and swelling does not directly address the client's reported dry mouth.
