Questions About the Respiratory System With Answers Questions
Question 1 of 5
The organ of the respiratory system where air is warmed moistened and cleaned is the:
Correct Answer: D
Rationale: The correct answer is D, "All of the above." The nose warms, moistens, and filters air, the pharynx continues this process, and the larynx further filters and humidifies air. Choosing option D is correct because all three structures work together to prepare air for the lungs. Option A, the nose, is correct but does not cover the entire process. Options B and C, the pharynx and larynx, are also involved in the warming, moistening, and cleaning of air, but individually they do not perform all these functions.
Question 2 of 5
Nurse Oliver observes constant bubbling in the water-seal chamber of a closed chest drainage system. What should the nurse conclude?
Correct Answer: C
Rationale: The nurse should conclude that the closed chest drainage system has an air leak. Constant bubbling in the water-seal chamber indicates air is escaping from the system, which can lead to a loss of negative pressure needed for proper chest drainage. This could result in inadequate lung re-expansion and increased risk of pneumothorax. A: Incorrect, constant bubbling is not normal. B: Incorrect, pneumothorax would not cause constant bubbling. D: Incorrect, chest tube obstruction would not cause bubbling in the water-seal chamber.
Question 3 of 5
The characteristic of COPD that puts the patient at risk for the nursing diagnosis of "Imbalanced nutrition: less than body requirements" is:
Correct Answer: D
Rationale: The correct answer is D, Excessive respiratory effort. In COPD, the increased work of breathing due to impaired lung function leads to higher energy expenditure, resulting in decreased appetite and weight loss. This increased respiratory effort can lead to fatigue, making it difficult for the patient to eat adequately, resulting in imbalanced nutrition. Choices A, B, and C do not directly contribute to imbalanced nutrition in COPD patients. A, Increased metabolism, is not a typical feature of COPD. B, Anxiety, may affect appetite but is not the primary reason for imbalanced nutrition in COPD. C, Chronic constipation, may cause discomfort but does not directly impact nutritional intake in the same way as excessive respiratory effort.
Question 4 of 5
The recommended diet for the patient who is dyspneic is a soft diet with:
Correct Answer: D
Rationale: The correct answer is D: Frequent, small meals. This is recommended for a dyspneic patient to prevent feeling overly full and to reduce the effort required for digestion, thus minimizing the risk of exacerbating breathing difficulties. Three large meals (A) would likely cause discomfort and increase difficulty in breathing. A low-protein emphasis (B) is not specifically indicated for dyspneic patients unless there are underlying conditions that require protein restriction. A low-calorie emphasis (C) may lead to inadequate nutrient intake, which is crucial for supporting the body's overall health and healing process.
Question 5 of 5
In humans ventilation is powered by
Correct Answer: D
Rationale: The correct answer is D because ventilation in humans is powered by the diaphragm and muscles attached to the ribs working together. The diaphragm contracts during inhalation, increasing the volume of the thoracic cavity, while the external intercostal muscles lift the rib cage, expanding the chest cavity. This creates a pressure difference, causing air to move into the lungs. The other choices are incorrect because the lungs themselves do not have the ability to power ventilation independently, and muscles attached to the ribs are essential for chest expansion during breathing.
