Multiple Choice Questions and Answers on Respiratory System Questions
Question 1 of 5
Palpation is the assessment technique used to find which abnormal assessment findings?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Residual volume of the lung is
Correct Answer: A
Rationale: The correct answer is A: 1200 ml. Residual volume is the amount of air left in the lungs after maximum expiration. It is around 1200 ml because it cannot be exhaled due to lung elasticity. Choice B (1500 ml) is incorrect as it is higher than the normal range. Choice C (4500 ml) is incorrect as it is too high for residual volume. Choice D (500 ml) is incorrect as it is too low for residual volume.
Question 3 of 5
Foetal hemoglobin has great affinity than adult hemoglobin because
Correct Answer: A
Rationale: The correct answer is A because 2,3 DPG binds less avidly to the Gamma polypeptide chain in foetal hemoglobin, resulting in a higher affinity for oxygen. This is due to structural differences between foetal and adult hemoglobin. Choice B is incorrect as high concentration alone does not determine affinity. Choice C is incorrect as the source of oxygen does not affect hemoglobin's affinity. Choice D is incorrect as the speed of oxygen binding does not necessarily correlate with affinity.
Question 4 of 5
Cloacal respiration is found in
Correct Answer: B
Rationale: Cloacal respiration is found in turtles and tortoises. These reptiles can absorb oxygen through their cloaca, a multi-functional opening used for excretion and reproduction. Turtles and tortoises lack specialized respiratory organs like lungs, and thus utilize cloacal respiration as an additional means of obtaining oxygen. Snakes (Option A) primarily rely on lung respiration. Crocodiles (Option C) have well-developed lungs for breathing. Frogs (Option D) respire through their skin and lungs but do not utilize cloacal respiration like turtles and tortoises. Therefore, the correct answer is B, as it is the only species listed that exhibits cloacal respiration.
Question 5 of 5
The medical nurse who works on a pulmonology unit is aware that several respiratory conditions can affect lung tissue compliance. The presence of what condition would lead to an increase in lung compliance?
Correct Answer: A
Rationale: The correct answer is A: Emphysema. Emphysema leads to an increase in lung compliance due to the destruction of alveolar walls, resulting in decreased elastic recoil. This decreased recoil makes it easier for the lungs to expand and increases overall lung compliance. Incorrect choices: B: Pulmonary fibrosis - Pulmonary fibrosis causes lung tissue scarring and stiffening, resulting in decreased lung compliance. C: Pleural effusion - Pleural effusion is an accumulation of fluid in the pleural space, which can restrict lung expansion and decrease lung compliance. D: Acute respiratory distress syndrome (ARDS) - ARDS causes inflammation and fluid buildup in the lungs, leading to decreased lung compliance due to increased stiffness and reduced ability to expand.
