Questions for the Respiratory System Questions
Question 1 of 5
In pleurisy,
Correct Answer: B
Rationale: The correct answer is B because pleurisy is inflammation of the pleural membrane, causing pain during breathing due to friction between the inflamed layers. Choice A is incorrect as alveoli are not directly affected in pleurisy. Choice C is incorrect as pleurisy does not cause cramps in the diaphragm. Choice D is incorrect as the vagus nerve irritation is not a characteristic feature of pleurisy.
Question 2 of 5
Respiration involves one of the following sets of processes
Correct Answer: A
Rationale: The correct answer is A because it accurately describes the processes involved in respiration. Inspiration is the intake of oxygen, exchange of gases occurs in the lungs where oxygen is taken in and carbon dioxide is released, and expiration is the process of exhaling carbon dioxide. Option B is incorrect because aspiration refers to the act of inhaling foreign objects or substances, not a part of normal respiration. Option C is incorrect because it does not accurately describe the sequence of processes in respiration. Option D is incorrect as the processes listed in option A are indeed involved in respiration.
Question 3 of 5
Partial pressure of oxygen in the inspired and expired air is respectively
Correct Answer: A
Rationale: The correct answer is A (158 and 116 mm Hg) because in inspired air, the partial pressure of oxygen is around 158 mm Hg, which corresponds to the atmospheric oxygen level. During expiration, some oxygen is exchanged for carbon dioxide, leading to a decrease in oxygen partial pressure to around 116 mm Hg. Choice B is incorrect because the partial pressure of oxygen in expired air is not as high as 40 mm Hg, which is too low for the oxygen content in the air we breathe. Choice C is incorrect because the partial pressure of oxygen in inspired air is not exactly 100 mm Hg, and the partial pressure in expired air is not as close to 95 mm Hg. Choice D is incorrect because the partial pressure of oxygen in inspired air is not as low as 40 mm Hg, and the partial pressure in expired air is not as high as 95 mm Hg.
Question 4 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 5 of 5
A client with a new tracheostomy is being seen in the oncology clinic. What finding by the nurse best indicates that goals for the client's decrease in self-esteem are being met?
Correct Answer: B
Rationale: The correct answer is B because joining a book club shows an improvement in social engagement and participation, indicating an increase in self-esteem. This choice demonstrates the client's interest in activities outside of their healthcare needs, promoting a sense of normalcy and connection. In contrast, options A, C, and D focus solely on stoma care and physical aspects, not directly related to self-esteem. Understanding stoma care (A) is important but does not address self-esteem directly. Family assistance (C) is supportive but does not necessarily indicate an improvement in the client's self-esteem. Skin integrity (D) is essential for physical health but does not reflect self-esteem.
