Questions of Respiratory System Questions
Question 1 of 5
Which of the following age-based changes is false?
Correct Answer: C
Rationale: The correct answer is C because vital capacity actually decreases with age due to changes in lung elasticity and muscle strength. A is correct as aging causes the lungs to lose elastic tissue. B is correct as lung compliance changes with age. D is correct as respiratory muscles weaken over time. Therefore, only option C is false in the context of age-related changes in lung function.
Question 2 of 5
diaphragm relaxes and decrease thoracic space in which phase of respiration.
Correct Answer: B
Rationale: During expiration, the diaphragm relaxes, causing it to move upwards, which decreases the thoracic space. This leads to the expulsion of air from the lungs. In contrast, during inspiration, the diaphragm contracts and moves downwards, increasing the thoracic space to allow air to enter the lungs. Option C, Pause, does not involve any specific respiratory phase. Option D, both a and b, is incorrect because during inspiration, the diaphragm contracts and increases thoracic space. Therefore, the correct answer is B, expiration, as this phase specifically involves the relaxation of the diaphragm and the decrease in thoracic space.
Question 3 of 5
Comiculate are the paired cartilage of pharynx in which shape
Correct Answer: B
Rationale: The correct answer is B: horn shape. The corniculate cartilages are small, horn-shaped structures located on the apex of the arytenoid cartilages in the larynx. These cartilages play a role in supporting the vocal folds. The other choices (A, C, D) are incorrect because the corniculate cartilages are not club-shaped, bate-shaped, or butterfly-shaped. It is crucial to understand the anatomical structure and function of the corniculate cartilages to identify the correct shape accurately.
Question 4 of 5
The home health nurse is making an initial call on a newly diagnosed tuberculosis (TB) patient. The patient lives with his wife and child. Which infection control instructions shouldn't the nurse include in the teaching plan?
Correct Answer: C
Rationale: The correct answer is C because TB is transmitted through droplet transmission, not airborne. The nurse should include hand hygiene (D) to prevent spread through contact, proper medication adherence (B) to treat TB effectively, and proper disposal of contaminated materials (A) to prevent spread through fomites. Implementing airborne precautions is not necessary for TB, as it does not remain suspended in the air for long periods.
Question 5 of 5
In teaching a patient with hypertension about controlling the illness the nurse recognizes that?
Correct Answer: D
Rationale: Rationale: D is correct because lifestyle modifications, such as exercise and diet changes, are essential for managing hypertension. This approach can help lower blood pressure without the need for drug therapy. A is incorrect because not all patients with elevated BP require medication. B is incorrect as weight loss is beneficial but not the only factor in controlling BP. C is incorrect because limiting salt intake remains important even if taking a diuretic.
