Questions of Respiratory System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
If his R = 0.8 how much will his arterial pO2 fall?
Correct Answer: D
Rationale: The correct answer is D (50mmHg). To calculate the fall in arterial pO2, we use the formula: Fall in pO2 = (Initial pO2) - (Initial pO2 x R). If R = 0.8, the fall in pO2 = (100mmHg) - (100mmHg x 0.8) = 100mmHg - 80mmHg = 20mmHg. Therefore, the arterial pO2 will fall by 20mmHg. Among the choices, D (50mmHg) is the closest to the calculated value of 20mmHg, making it the correct answer. Other choices (A, B, C) do not align with the calculated fall in pO2.
Question 5 of 5
The organ of the respiratory system that is kept open by rings of cartilage is the:
Correct Answer: D
Rationale: The correct answer is D: trachea. The trachea is kept open by rings of cartilage to prevent collapse during inhalation. The nose (A) is primarily involved in filtering, warming, and moistening air. The pharynx (B) is a common pathway for both air and food. The larynx (C) houses the vocal cords and aids in sound production but does not have cartilage rings to keep it open.
