Multiple Choice Questions on Respiratory System Questions
Question 1 of 5
The maximum amount of air that can be taken into the lungs in a single deep breath is the
Correct Answer: A
Rationale: The correct answer is A: vital capacity. Vital capacity is the maximum amount of air a person can exhale after taking the deepest breath possible. It is calculated by adding tidal volume, inspiratory reserve volume, and expiratory reserve volume together. This measurement reflects the maximum lung capacity and is important in assessing lung function. Tidal volume (B) is the amount of air inhaled and exhaled during normal breathing cycles. Pleural volume (C) refers to the space between the lungs and the chest wall. Alveolar volume (D) is the amount of air in the alveoli available for gas exchange. These choices are incorrect as they do not represent the maximum air intake capacity of the lungs.
Question 2 of 5
Number of alveoli in the two human lungs is
Correct Answer: A
Rationale: The correct answer is A (600-800 millions) because the alveoli are tiny air sacs in the lungs responsible for gas exchange. An adult human lung has approximately 300-400 million alveoli, with two lungs totaling 600-800 million. Choice B (200-300 millions) and C (1-2 millions) are incorrect because they underestimate the total number of alveoli in both lungs. Choice D (100,000-150,000 millions) is incorrect as it overestimates the number of alveoli by a significant margin.
Question 3 of 5
The process of respiration is concerned with
Correct Answer: D
Rationale: The correct answer is D: liberation of energy. Respiration involves the conversion of glucose into ATP, releasing energy that cells can use for various functions. Oxygen is taken in during respiration (A), not liberated (B). Carbon dioxide is released (C) as a byproduct of respiration, not liberated. Option D is correct as it accurately captures the primary purpose of respiration.
Question 4 of 5
A nurse teaches a client who is prescribed nicotine replacement therapy. Which statement would the nurse include in this client's teaching?
Correct Answer: C
Rationale: The correct answer is C: Smoking while taking this medication will increase your risk of a stroke. This statement is important because nicotine replacement therapy aims to help the client quit smoking, and smoking while on this therapy can lead to nicotine overdose, increasing the risk of adverse effects like stroke. Choice A is incorrect as it does not directly relate to the client's nicotine replacement therapy. Choice B is incorrect as it pertains to orthostatic hypotension, not nicotine replacement therapy. Choice D is incorrect as it addresses the consequences of abruptly stopping the medication, not the risks associated with smoking while on it.
Question 5 of 5
A nurse cares for a client who has hypertension that has not responded well to several medications. The client states compliance is not an issue. What action would the nurse take next?
Correct Answer: A
Rationale: The correct answer is A: Assess the client for obstructive sleep apnea. Hypertension that is not responding to medications may be due to underlying sleep apnea, a common comorbidity. By assessing for obstructive sleep apnea, the nurse can identify a potential contributing factor to the client's uncontrolled hypertension. This step is crucial in managing the client's condition effectively. Summary of other choices: B: Arranging a home sleep apnea test may be premature without first assessing the client for obstructive sleep apnea. C: Encouraging the client to begin exercising is important for overall health but may not directly address the uncontrolled hypertension. D: Scheduling a polysomnography may be necessary if obstructive sleep apnea is suspected after the initial assessment.
