Multiple Choice Questions on Respiratory System Questions
Question 1 of 5
Of the four parts of respiration the part when oxygen and carbon dioxide are exchanged in the body's tissue cells is:
Correct Answer: D
Rationale: The correct answer is D: internal respiration. This is the part of respiration where oxygen and carbon dioxide are exchanged in the body's tissue cells. During internal respiration, oxygen is delivered to the cells and carbon dioxide is removed. Pulmonary ventilation (choice A) refers to the process of breathing where air is moved in and out of the lungs. External respiration (choice B) is the exchange of gases between the lungs and blood. Transport of respiratory gases (choice C) involves the circulation of oxygen and carbon dioxide in the bloodstream. Internal respiration specifically focuses on the exchange of gases within the tissue cells, making it the correct choice in this scenario.
Question 2 of 5
A female client must take streptomycin for tuberculosis. Before therapy begins, the nurse should instruct the client to notify the physician if a health concern occurs?
Correct Answer: C
Rationale: The correct answer is C: Decreased hearing acuity. Streptomycin is known to cause ototoxicity, which can lead to decreased hearing acuity. Therefore, the nurse should instruct the client to notify the physician if any changes in hearing occur to prevent permanent hearing loss. Impaired color discrimination (A) and increased appetite (D) are not commonly associated with streptomycin use. Increased urinary frequency (B) is not a typical side effect of streptomycin and would not require immediate physician notification.
Question 3 of 5
A nurse is caring for a client with acute respiratory distress syndrome. Which of the following would the nurse expect to note in the client?
Correct Answer: C
Rationale: The correct answer is C: Low arterial PaO2. In acute respiratory distress syndrome (ARDS), there is impaired gas exchange leading to hypoxemia. Low arterial PaO2 indicates poor oxygenation in the blood, a hallmark of ARDS. Decreased respiratory rate (A) is unlikely as the body compensates by increasing respiratory effort. Pallor (B) is a general sign of reduced blood flow and not specific to ARDS. An elevated arterial PaO2 (D) would not be expected in ARDS, as it signifies adequate oxygenation.
Question 4 of 5
A client is admitted with chronic obstructive pulmonary disease (COPD). Which of the following signs and symptoms aren't characteristic of COPD?
Correct Answer: A
Rationale: The correct answer is A: Fever. Fever is not a characteristic sign or symptom of COPD. The rationale is that COPD is a chronic respiratory condition that primarily affects the lungs and airways, leading to symptoms such as shortness of breath (dyspnea on exertion), barrel chest due to air trapping, and clubbed fingers and toes due to chronic hypoxia. Fever is not a typical presentation of COPD, as it is usually associated with infections or inflammatory conditions rather than COPD itself. In summary, choices B, C, and D are characteristic of COPD, while choice A is not typically associated with this condition.
Question 5 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.
