NCLEX Questions for Respiratory System Questions
Question 1 of 5
A section of the lung that receives its own tertiary bronchus is called the ________.
Correct Answer: A
Rationale: The correct answer is A: bronchopulmonary segment. This segment of the lung is supplied by its own tertiary bronchus, allowing for independent ventilation. Bronchopulmonary segments are functional units of the lung with their own blood supply and bronchial branches. B: Pulmonary lobule is incorrect as it refers to a small unit of lung tissue surrounded by connective tissue septa. C: Interpulmonary segment is not a recognized term in anatomy. D: Respiratory segment is not a specific anatomical term related to the lung's bronchial divisions.
Question 2 of 5
pharynx subdivided to how many parts ?
Correct Answer: A
Rationale: The pharynx is divided into three parts: nasopharynx, oropharynx, and laryngopharynx. The nasopharynx connects the nasal cavity to the oropharynx, which connects to the oral cavity, and then the laryngopharynx connects to the esophagus and larynx. Therefore, the correct answer is A (3 parts). Choices B, C, and D are incorrect because the pharynx is not subdivided into 2, 4, or 5 parts based on its anatomical structure.
Question 3 of 5
The nurse is caring for a patient with a closed-chest drainage system with chest tubes. Which observation confirms that the system is intact and working?
Correct Answer: A
Rationale: The correct answer is A because fluctuations in the water level in the water-seal chamber indicate that the system is intact and working properly. When the water level fluctuates, it signifies that the system is maintaining the pressure gradient needed for proper drainage and lung re-expansion. Explanation of why other choices are incorrect: B: The level of fluid in the collection chamber rising does not confirm the system's integrity or functionality. C: Constant bubbles in the water-seal chamber indicate an air leak, which is not desirable in a closed-chest drainage system. D: Attaching suction is a step in setting up the system but does not confirm ongoing function or integrity.
Question 4 of 5
An older client has been diagnosed with possible white coat hypertension. Which of the following client interventions would need to be implemented to address this issue?
Correct Answer: A
Rationale: The correct answer is A: Teach the client how to self-monitor and record BPs at home. This is the best intervention to address white coat hypertension as it allows the client to monitor their blood pressure in a relaxed environment, reducing the impact of anxiety from clinic visits. Self-monitoring can provide more accurate readings over time. Choice B focuses on stress levels, which may not directly address the issue. Choice C is unrelated to white coat hypertension. Choice D involves regular clinic visits, which may not address the underlying anxiety-related increase in blood pressure.
Question 5 of 5
Which statement by a client is consistent with a diagnosis of heart failure?
Correct Answer: D
Rationale: The correct answer is D: "I have trouble breathing when I climb a flight of stairs." This statement indicates exertional dyspnea, a common symptom of heart failure due to impaired cardiac function leading to inadequate oxygen delivery. Shortness of breath with exertion is a hallmark sign of heart failure, as the heart's inability to pump effectively results in fluid accumulation in the lungs, causing difficulty in breathing during physical activities. Choices A, B, and C do not directly correlate with heart failure symptoms. Seeing spots before eyes (A) may suggest visual issues, tiredness at the end of the day (B) is a common complaint and can be due to various reasons, while feeling bloated after a meal (C) could be related to gastrointestinal issues.
