Multiple Choice Questions About Respiratory System Questions
Question 1 of 5
A client with suspected tuberculosis will most likely relate which clinical manifestations?
Correct Answer: A
Rationale: The correct answer is A. A client with suspected tuberculosis is likely to experience fatigue, weight loss, low-grade fevers, and night sweats due to the chronic infection affecting the body. Fatigue and weight loss are common symptoms of active tuberculosis due to the systemic impact of the infection. Low-grade fevers and night sweats are characteristic of tuberculosis due to the body's immune response. These symptoms are key indicators of tuberculosis infection. Choices B, C, and D are incorrect because they describe symptoms that are not typically associated with tuberculosis. Dyspnea, chest pain, and cough (Choice B) are more commonly seen in respiratory conditions such as pneumonia or bronchitis. Rapid shallow breathing, prolonged labored expiration, and stridor (Choice C) are indicative of airway obstruction rather than tuberculosis. Dyspnea, hypoxemia, and decreased pulmonary compliance (Choice D) are more characteristic of conditions such as chronic obstructive pulmonary disease (COPD) rather than tuberculosis.
Question 2 of 5
For the surface of an animal to function in the integumentary exchange of gases it must
Correct Answer: D
Rationale: The correct answer is D because for the integumentary exchange of gases to occur efficiently, the surface of the animal must meet all three criteria: be thin and soft to allow gases to pass through easily, have a high number of blood vessels to facilitate gas exchange, and have a mucus or moist covering to prevent desiccation and aid in gas diffusion. If the surface is not thin and soft, gases cannot diffuse effectively. Without a high number of blood vessels, there wouldn't be sufficient transport of gases to and from the surface. And without a mucus or moist covering, the surface may dry out, hindering gas exchange. Therefore, all of the above factors are essential for the integumentary exchange of gases to function optimally.
Question 3 of 5
Carbon monoxide
Correct Answer: D
Rationale: The correct answer is D because carbon monoxide can indeed arise from cigarette smoke due to incomplete combustion of tobacco. This is supported by scientific evidence. Carbon monoxide has a high affinity for hemoglobin, so choice A is incorrect. It can be transported by the circulatory system, making choice B incorrect. Breathing excessive amounts of automobile exhaust containing carbon monoxide can lead to death, making choice C incorrect.
Question 4 of 5
Pneumatic and inhibitory centers are associated with
Correct Answer: B
Rationale: The correct answer is B: Breathing. Pneumatic and inhibitory centers are associated with controlling the process of breathing. The pneumatic center regulates the rate and depth of breathing, while the inhibitory center helps in controlling the duration and intensity of breathing. Therefore, these centers are directly involved in the overall process of breathing. Choices A, C, and D are incorrect as they are specific components or stages of the breathing process, whereas the correct answer encompasses the entire act of breathing, making it the most comprehensive and appropriate choice.
Question 5 of 5
Respiratory mechanism is controlled by
Correct Answer: A
Rationale: The correct answer is A: Central nervous system. The respiratory mechanism is controlled by the brainstem, specifically the medulla oblongata and pons. These areas of the central nervous system regulate breathing by monitoring levels of carbon dioxide and oxygen in the blood. The medulla sets the basic rhythm of breathing, while the pons helps fine-tune the breathing rate. Choices B, C, and D are incorrect because while the sympathetic and parasympathetic nervous systems are involved in regulating various bodily functions, they do not directly control the respiratory mechanism. The autonomic nervous system, which includes both the sympathetic and parasympathetic divisions, plays a role in involuntary functions like heart rate and digestion, but it is not the primary controller of breathing.
