Multiple Choice Questions on Respiratory System Questions
Question 1 of 5
After inspiration commences the:
Correct Answer: A
Rationale: After inspiration commences, the diaphragm contracts and the thoracic cavity expands. This leads to a decrease in intrapleural pressure, allowing the lungs to expand. Simultaneously, intrapulmonary pressure decreases, creating a pressure gradient for air to flow into the lungs. Choice A is correct because both intrapleural pressure and intrapulmonary pressure fall during inspiration. Choice B is incorrect because intrapulmonary pressure actually decreases during inspiration, not rises. Choice C is incorrect because intrapleural pressure falling does not directly correlate with a decrease in venous return. Choice D is incorrect because during inspiration, the volume of the alveoli increases as the lungs expand, causing intrapulmonary pressure to decrease.
Question 2 of 5
For a female patient with chronic obstructive pulmonary disease, which nursing intervention would help maintain a patent airway?
Correct Answer: C
Rationale: The correct answer is C: Teaching the patient how to perform controlled coughing. This intervention helps to clear mucus and secretions from the airways, maintaining a patent airway. Controlled coughing also prevents airway obstruction and promotes effective breathing. Restricting fluid intake (A) can lead to dehydration and thickening of secretions, worsening airway clearance. Enforcing bed rest (B) can cause decreased lung expansion and retention of secretions. Administering sedatives (D) can depress respiratory drive and worsen respiratory function.
Question 3 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 4 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 5 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.
