Multiple Choice Questions on Respiratory System Questions
Question 1 of 5
What is an advantage of a tracheostomy over an endotracheal (ET) tube for long-term management of an upper airway obstruction?
Correct Answer: C
Rationale: A tracheostomy tube allows for more comfort and mobility compared to an endotracheal tube, making it preferable for long-term management of an upper airway obstruction. The ability to speak, eat, and move more freely with a tracheostomy tube can significantly improve the quality of life for the patient.
Question 2 of 5
Chlorocruorin is a copper-containing blood pigment found in some annelids like Sabella. Its colour in both oxygenated and deoxygenated states is
Correct Answer: C
Rationale: Step 1: Chlorocruorin contains copper, giving it a green color. Step 2: In oxygenated state, chlorocruorin appears green due to the presence of copper. Step 3: In deoxygenated state, chlorocruorin retains its green color. Step 4: Therefore, the correct answer is C: Green. Summary: A (Blue) and B (Red) are incorrect as chlorocruorin is green due to copper. D (Blue red) is incorrect as it does not reflect the true color of chlorocruorin.
Question 3 of 5
2,3 DPG causes shifting of Oxygen dissociation curve in Adult Hb to Right because
Correct Answer: B
Rationale: The correct answer is B because 2,3 DPG binds to the Beta chain of Hemoglobin, reducing its oxygen affinity, causing a right shift in the Oxygen dissociation curve. This change allows for easier oxygen unloading in tissues. Choice A is incorrect as 2,3 DPG decreases, not increases, oxygen affinity. Choice C is irrelevant as its concentration is not a factor in the shifting of the curve. Choice D is incorrect as 2,3 DPG does bind to Hemoglobin, specifically to the Beta chain.

Question 5 of 5
A patient has been diagnosed with heart failure that has not yet responded to treatment. What breath sound should the nurse expect to assess on auscultation?
Correct Answer: D
Rationale: The correct answer is D: Crackles. In heart failure, crackles are often heard on auscultation due to fluid accumulation in the lungs. This is a result of the heart's inability to effectively pump blood, leading to congestion in the pulmonary circulation. Crackles are discontinuous, moist sounds that occur during inspiration and sometimes expiration. Expiratory wheezes (A) are typically associated with obstructive airway diseases such as asthma. Inspiratory wheezes (B) are not commonly heard in heart failure. Rhonchi (C) are low-pitched continuous sounds often heard in patients with bronchitis or pneumonia, not specifically in heart failure.
