NCLEX Questions for Respiratory System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
Which one is not correct? A patient suffering from anaemia with an Hb concentration of 5g/100ml
Correct Answer: D
Rationale: The correct answer is D because in a patient with anemia and low hemoglobin concentration, their PaO2 will be decreased due to reduced oxygen-carrying capacity of blood. This is a result of decreased oxygen saturation in the blood. A: Decreased TPR is incorrect because anemia can lead to compensatory mechanisms such as increased sympathetic tone and vasoconstriction, resulting in increased total peripheral resistance. B: Increased cardiac output is incorrect as the heart may need to work harder to maintain oxygen delivery to tissues due to decreased oxygen-carrying capacity. C: Increased 2,3 DPG in RBC is incorrect because anemia can lead to decreased 2,3 DPG levels, which shift the oxygen-hemoglobin dissociation curve to the left, impairing oxygen release to tissues.
Question 5 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.
