Questions of Respiratory System Questions
Question 1 of 5
Which chamber of the heart is most commonly affected in heart failure?
Correct Answer: C
Rationale: The correct answer is C: Left ventricle. The left ventricle is the chamber responsible for pumping oxygenated blood to the rest of the body, making it the most commonly affected in heart failure. When the left ventricle weakens or becomes stiff, it can lead to inefficient pumping, causing fluid buildup and symptoms of heart failure. The other choices, A: Left atrium, B: Right atrium, and D: Right ventricle, are less commonly affected in heart failure as they have different functions in the heart's circulation.
Question 2 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 3 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 4 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.
Question 5 of 5
A client with pneumonia has a fever of 101.4° F (38.6° C) a nonproductive cough and an O2 saturation of 88%. The client is weak and needs assistance to get out of bed. Which client problem should the nurse assign as the priority?
Correct Answer: D
Rationale: The correct answer is D, Impaired gas exchange. This is the priority because the client's O2 saturation of 88% indicates poor oxygenation, which can lead to serious complications like hypoxemia. The fever and nonproductive cough are symptoms of pneumonia contributing to impaired gas exchange. Addressing this issue is crucial to prevent respiratory distress. A: Fatigue - While important, fatigue is a secondary concern compared to impaired gas exchange, which directly affects oxygenation and can be life-threatening. B: Hyperthermia - The client's fever is likely related to the pneumonia but managing impaired gas exchange takes precedence as it directly impacts oxygen delivery to tissues. C: Impaired mobility - While assisting the client out of bed is necessary, the priority is to address the underlying problem of impaired gas exchange to prevent respiratory compromise.
